    • + *
  • Montgomery: y^2 = x^3 + A x^2 + x mod P (Curve25519, + * Curve448)
+ * In both cases, the generator (\p G) for a prime-order subgroup is fixed. + * + * For Short Weierstrass, this subgroup is the whole curve, and its + * cardinality is denoted by \p N. Our code requires that \p N is an + * odd prime as mbedtls_ecp_mul() requires an odd number, and + * mbedtls_ecdsa_sign() requires that it is prime for blinding purposes. + * + * For Montgomery curves, we do not store \p A, but (A + 2) / 4, + * which is the quantity used in the formulas. Additionally, \p nbits is + * not the size of \p N but the required size for private keys. + * + * If \p modp is NULL, reduction modulo \p P is done using a generic algorithm. + * Otherwise, \p modp must point to a function that takes an \p mbedtls_mpi in the + * range of 0..2^(2*pbits)-1, and transforms it in-place to an integer + * which is congruent mod \p P to the given MPI, and is close enough to \p pbits + * in size, so that it may be efficiently brought in the 0..P-1 range by a few + * additions or subtractions. Therefore, it is only an approximative modular + * reduction.

This edition of Mbed TLS does not include the test code or scripts used in the development of the library. You can find these in the standalone release. + +### Getting started + +Several example programs are available that demonstrate Mbed TLS with Mbed OS. These can help you become familiar with the library: + +* [**TLS Client:**](https://github.com/ARMmbed/mbed-os-example-tls/tree/master/tls-client) TLS Client demonstrates the use of Mbed TLS to establish a TLS connection to a remote server. + +* [**Benchmark:**](https://github.com/ARMmbed/mbed-os-example-tls/tree/master/benchmark) Benchmark measures the time taken to perform basic cryptographic functions used in the library. + +* [**Hashing:**](https://github.com/ARMmbed/mbed-os-example-tls/tree/master/hashing) Hashing demonstrates the various APIs for computing hashes of data (also known as message digests) with SHA-256. + +* [**Authenticated encryption:**](https://github.com/ARMmbed/mbed-os-example-tls/tree/master/authcrypt) Authcrypt demonstrates usage of the cipher API for encrypting and authenticating data with AES-CCM. + +These examples are fully integrated into Mbed OS. Each of them comes with complete usage instructions as a `README.md` file. + +### Configuring Mbed TLS features + +With Mbed TLS, you can disable any unneeded features during compilation for a particular project. The default configuration enables widely used features of the TLS protocol, which meets the needs of most projects. It also disables all older and less common features to minimize the code footprint. + +The list of available compilation flags is available in the fully documented [`config.h` file](https://github.com/ARMmbed/mbedtls/blob/development/include/mbedtls/config.h). + +If you need to adjust these flags, you can provide your own supplementary configuration adjustment file with suitable `#define` and `#undef` statements. These are included between the default definitions and the sanity checks. Your configuration file should be in your application's include directory and can be named freely, but you then need to tell Mbed TLS the file's name. To do that, you can use the [Mbed OS configuration system](https://os.mbed.com/docs/latest/reference/configuration.html). + +For example, if you wanted to enable the options `MBEDTLS_PEM_WRITE_C` and `MBEDTLS_CMAC_C` and provide your own additional configuration file for Mbed TLS named `my_config.h`, you could define these in a top level `mbed_app.json` configuration file in the root directory of your project. + +The Mbed TLS configuration file would be specified in the `.json` file as: + +``` +{ + "macros" : [ + + "MBEDTLS_USER_CONFIG_FILE" : "my_config.h", + + "MBEDTLS_PEM_WRITE_C", + "MBEDTLS_CMAC_C" + ] + [remainder of file] +} +``` + +You can then use the additional configuration file `my_config.h` as a normal configuration header file to include or exclude configurations. For example, it could include the following lines to include ECJPAKE, and to disable the CBC block mode: + +``` + #define MBEDTLS_ECJPAKE_C + #define MBEDTLS_KEY_EXCHANGE_ECJPAKE_ENABLED + + #undef MBEDTLS_CIPHER_MODE_CBC +``` + +You can use this to change any configuration normally in the `config.h` file. + +### Getting Mbed TLS from GitHub + +We maintain and develop Mbed TLS in the open, independently of Mbed OS, and you can find its source on GitHub here: [ARMmbed/mbedtls](https://github.com/ARMmbed/mbedtls). To import a different version of Mbed TLS into an instance of Mbed OS, there is a `Makefile` script to update the local Git repository, extract a specific version and modify the configuration files to Mbed OS defaults. + +To use the `Makefile`, you can either set `MBED_TLS_RELEASE` environment variable to the Git tag or commit ID of the Mbed TLS release or version you want to use, or modify the `Makefile` itself. If `MBED_TLS_RELEASE` is not set, the HEAD of the main development branch will be extracted. + +Run the following commands in the `importer` directory in the Mbed TLS directory: + +``` + make update + make +``` + +The `make update` command pulls the specified version of Mbed TLS into the local `importer/TARGET_IGNORE` directory, and `make` transforms it into the `src` directory, modifying its configuration file as necessary. + +Once these steps are complete, you can build Mbed OS normally with the new version of Mbed TLS. + +### Differences between the standalone and Mbed OS editions + +Although the two editions share the same code base, there are differences, mainly in configuration and integration. Remember these differences if you consult our [knowledge base](https://tls.mbed.org/kb), as the knowledge base articles refer to the standalone edition. + +* The Mbed OS edition has a smaller set of features enabled by default in `config.h`, to reduce footprint. Although the default configuration of the standalone edition puts more emphasis on maintaining interoperability with old peers, the Mbed OS edition only enables the most modern ciphers and the latest version of (D)TLS. + +* The following components of Mbed TLS are disabled in the Mbed OS edition: `net_sockets.c` and `timing.c`. This is because Mbed OS includes its own equivalents. + +### Help and support + +For further documentation and help, you can visit the [Mbed TLS website](https://tls.mbed.org/), which contains full documentation of the library, including function-by-function descriptions, knowledge base articles and blogs. Additionally, you can join our [support forum](https://forums.mbed.com/c/mbed-tls) for questions to the community or to help others. + +### Contributing to the project + +We gratefully accept bug reports and contributions from the community. Contributions should be submitted to the [standalone Mbed TLS project](https://github.com/ARMmbed/mbedtls), not to the version of Mbed TLS embedded within Mbed OS. + +Please see the [contributing guidelines](https://github.com/ARMmbed/mbedtls/blob/development/CONTRIBUTING.md) of the project for details on how to do this. diff --git a/connectivity/mbedtls/VERSION.txt b/connectivity/mbedtls/VERSION.txt new file mode 100644 index 0000000..4961d31 --- /dev/null +++ b/connectivity/mbedtls/VERSION.txt @@ -0,0 +1 @@ +mbedtls-2.22.0 diff --git a/connectivity/mbedtls/apache-2.0.txt b/connectivity/mbedtls/apache-2.0.txt new file mode 100644 index 0000000..d645695 --- /dev/null +++ b/connectivity/mbedtls/apache-2.0.txt @@ -0,0 +1,202 @@ + + Apache License + Version 2.0, January 2004 + http://www.apache.org/licenses/ + + TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION + + 1.

No explicit IV is contained + * in an encrypted record. The IV for the first record is extracted + * at key extraction time. In contrast, for TLS 1.1 and 1.2, no + * IV is generated at key extraction time, but every encrypted + * record is explicitly prefixed by the IV with which it was encrypted. + * - AEAD transformations ([D]TLS versions >= 1.2 only) + * These come in two fundamentally different versions, the first one + * used in TLS 1.2, excluding ChaChaPoly ciphersuites, and the second + * one used for ChaChaPoly ciphersuites in TLS 1.2 as well as for TLS 1.3. + * In the first transformation, the IV to be used for a record is obtained + * as the concatenation of an explicit, static 4-byte IV and the 8-byte + * record sequence number, and explicitly prepending this sequence number + * to the encrypted record. In contrast, in the second transformation + * the IV is obtained by XOR'ing a static IV obtained at key extraction + * time with the 8-byte record sequence number, without prepending the + * latter to the encrypted record. + * + * In addition to type and version, the following parameters are relevant: + * - The symmetric cipher algorithm to be used. + * - The (static) encryption/decryption keys for the cipher. + * - For stream/CBC, the type of message digest to be used. + * - For stream/CBC, (static) encryption/decryption keys for the digest. + * - For AEAD transformations, the size (potentially 0) of an explicit, + * random initialization vector placed in encrypted records. + * - For some transformations (currently AEAD and CBC in SSL3 and TLS 1.0) + * an implicit IV. It may be static (e.g. AEAD) or dynamic (e.g. CBC) + * and (if present) is combined with the explicit IV in a transformation- + * dependent way (e.g. appending in TLS 1.2 and XOR'ing in TLS 1.3). + * - For stream/CBC, a flag determining the order of encryption and MAC. + * - The details of the transformation depend on the SSL/TLS version. + * - The length of the authentication tag. + * + * Note: Except for CBC in SSL3 and TLS 1.0, these parameters are + * constant across multiple encryption/decryption operations. + * For CBC, the implicit IV needs to be updated after each + * operation. + * + * The struct below refines this abstract view as follows: + * - The cipher underlying the transformation is managed in + * cipher contexts cipher_ctx_{enc/dec}, which must have the + * same cipher type. The mode of these cipher contexts determines + * the type of the transformation in the sense above: e.g., if + * the type is MBEDTLS_CIPHER_AES_256_CBC resp. MBEDTLS_CIPHER_AES_192_GCM + * then the transformation has type CBC resp. AEAD. + * - The cipher keys are never stored explicitly but + * are maintained within cipher_ctx_{enc/dec}. + * - For stream/CBC transformations, the message digest contexts + * used for the MAC's are stored in md_ctx_{enc/dec}. These contexts + * are unused for AEAD transformations. + * - For stream/CBC transformations and versions > SSL3, the + * MAC keys are not stored explicitly but maintained within + * md_ctx_{enc/dec}. + * - For stream/CBC transformations and version SSL3, the MAC + * keys are stored explicitly in mac_enc, mac_dec and have + * a fixed size of 20 bytes. These fields are unused for + * AEAD transformations or transformations >= TLS 1.0. + * - For transformations using an implicit IV maintained within + * the transformation context, its contents are stored within + * iv_{enc/dec}. + * - The value of ivlen indicates the length of the IV. + * This is redundant in case of stream/CBC transformations + * which always use 0 resp. the cipher's block length as the + * IV length, but is needed for AEAD ciphers and may be + * different from the underlying cipher's block length + * in this case. + * - The field fixed_ivlen is nonzero for AEAD transformations only + * and indicates the length of the static part of the IV which is + * constant throughout the communication, and which is stored in + * the first fixed_ivlen bytes of the iv_{enc/dec} arrays. + * Note: For CBC in SSL3 and TLS 1.0, the fields iv_{enc/dec} + * still store IV's for continued use across multiple transformations, + * so it is not true that fixed_ivlen == 0 means that iv_{enc/dec} are + * not being used! + * - minor_ver denotes the SSL/TLS version + * - For stream/CBC transformations, maclen denotes the length of the + * authentication tag, while taglen is unused and 0. + * - For AEAD transformations, taglen denotes the length of the + * authentication tag, while maclen is unused and 0. + * - For CBC transformations, encrypt_then_mac determines the + * order of encryption and authentication.

It is therefore only necessary to know S at odd indices, + * which is why we are only computing half of it in the first place in + * ecp_precompute_comb and accessing it with index abs(i) / 2 in ecp_select_comb. + * + * - For the sake of compactness, only the seven low-order bits of x[i] + * are used to represent its absolute value (K_i in the paper), and the msb + * of x[i] encodes the sign (s_i in the paper): it is set if and only if + * if s_i == -1; + * + * Calling conventions: + * - x is an array of size d + 1 + * - w is the size, ie number of teeth, of the comb, and must be between + * 2 and 7 (in practice, between 2 and MBEDTLS_ECP_WINDOW_SIZE) + * - m is the MPI, expected to be odd and such that bitlength(m) <= w * d + * (the result will be incorrect if these assumptions are not satisfied) + */ +static void ecp_comb_recode_core( unsigned char x[], size_t d, + unsigned char w, const mbedtls_mpi *m ) +{ + size_t i, j; + unsigned char c, cc, adjust; + + memset( x, 0, d+1 ); + + /* First get the classical comb values (except for x_d = 0) */ + for( i = 0; i < d; i++ ) + for( j = 0; j < w; j++ ) + x[i] |= mbedtls_mpi_get_bit( m, i + d * j ) << j; + + /* Now make sure x_1 .. x_d are odd */ + c = 0; + for( i = 1; i <= d; i++ ) + { + /* Add carry and update it */ + cc = x[i] & c; + x[i] = x[i] ^ c; + c = cc; + + /* Adjust if needed, avoiding branches */ + adjust = 1 - ( x[i] & 0x01 ); + c |= x[i] & ( x[i-1] * adjust ); + x[i] = x[i] ^ ( x[i-1] * adjust ); + x[i-1] |= adjust << 7; + } +} + +/* + * Precompute points for the adapted comb method + * + * Assumption: T must be able to hold 2^{w - 1} elements. + * + * Operation: If i = i_{w-1} ... i_1 is the binary representation of i, + * sets T[i] = i_{w-1} 2^{(w-1)d} P + ... + i_1 2^d P + P. + * + * Cost: d(w-1) D + (2^{w-1} - 1) A + 1 N(w-1) + 1 N(2^{w-1} - 1) + * + * Note: Even comb values (those where P would be omitted from the + * sum defining T[i] above) are not needed in our adaption + * the comb method.

This edition of Mbed TLS does not include the test code or scripts used in the development of the library. You can find these in the standalone release. - -### Getting started - -Several example programs are available that demonstrate Mbed TLS with Mbed OS. These can help you become familiar with the library: - -* [**TLS Client:**](https://github.com/ARMmbed/mbed-os-example-tls/tree/master/tls-client) TLS Client demonstrates the use of Mbed TLS to establish a TLS connection to a remote server. - -* [**Benchmark:**](https://github.com/ARMmbed/mbed-os-example-tls/tree/master/benchmark) Benchmark measures the time taken to perform basic cryptographic functions used in the library. - -* [**Hashing:**](https://github.com/ARMmbed/mbed-os-example-tls/tree/master/hashing) Hashing demonstrates the various APIs for computing hashes of data (also known as message digests) with SHA-256. - -* [**Authenticated encryption:**](https://github.com/ARMmbed/mbed-os-example-tls/tree/master/authcrypt) Authcrypt demonstrates usage of the cipher API for encrypting and authenticating data with AES-CCM. - -These examples are fully integrated into Mbed OS. Each of them comes with complete usage instructions as a `README.md` file. - -### Configuring Mbed TLS features - -With Mbed TLS, you can disable any unneeded features during compilation for a particular project. The default configuration enables widely used features of the TLS protocol, which meets the needs of most projects. It also disables all older and less common features to minimize the code footprint. - -The list of available compilation flags is available in the fully documented [`config.h` file](https://github.com/ARMmbed/mbedtls/blob/development/include/mbedtls/config.h). - -If you need to adjust these flags, you can provide your own supplementary configuration adjustment file with suitable `#define` and `#undef` statements. These are included between the default definitions and the sanity checks. Your configuration file should be in your application's include directory and can be named freely, but you then need to tell Mbed TLS the file's name. To do that, you can use the [Mbed OS configuration system](https://os.mbed.com/docs/latest/reference/configuration.html). - -For example, if you wanted to enable the options `MBEDTLS_PEM_WRITE_C` and `MBEDTLS_CMAC_C` and provide your own additional configuration file for Mbed TLS named `my_config.h`, you could define these in a top level `mbed_app.json` configuration file in the root directory of your project. - -The Mbed TLS configuration file would be specified in the `.json` file as: - -``` -{ - "macros" : [ - - "MBEDTLS_USER_CONFIG_FILE" : "my_config.h", - - "MBEDTLS_PEM_WRITE_C", - "MBEDTLS_CMAC_C" - ] - [remainder of file] -} -``` - -You can then use the additional configuration file `my_config.h` as a normal configuration header file to include or exclude configurations. For example, it could include the following lines to include ECJPAKE, and to disable the CBC block mode: - -``` - #define MBEDTLS_ECJPAKE_C - #define MBEDTLS_KEY_EXCHANGE_ECJPAKE_ENABLED - - #undef MBEDTLS_CIPHER_MODE_CBC -``` - -You can use this to change any configuration normally in the `config.h` file. - -### Getting Mbed TLS from GitHub - -We maintain and develop Mbed TLS in the open, independently of Mbed OS, and you can find its source on GitHub here: [ARMmbed/mbedtls](https://github.com/ARMmbed/mbedtls). To import a different version of Mbed TLS into an instance of Mbed OS, there is a `Makefile` script to update the local Git repository, extract a specific version and modify the configuration files to Mbed OS defaults. - -To use the `Makefile`, you can either set `MBED_TLS_RELEASE` environment variable to the Git tag or commit ID of the Mbed TLS release or version you want to use, or modify the `Makefile` itself. If `MBED_TLS_RELEASE` is not set, the HEAD of the main development branch will be extracted. - -Run the following commands in the `importer` directory in the Mbed TLS directory: - -``` - make update - make -``` - -The `make update` command pulls the specified version of Mbed TLS into the local `importer/TARGET_IGNORE` directory, and `make` transforms it into the `src` directory, modifying its configuration file as necessary. - -Once these steps are complete, you can build Mbed OS normally with the new version of Mbed TLS. - -### Differences between the standalone and Mbed OS editions - -Although the two editions share the same code base, there are differences, mainly in configuration and integration. Remember these differences if you consult our [knowledge base](https://tls.mbed.org/kb), as the knowledge base articles refer to the standalone edition. - -* The Mbed OS edition has a smaller set of features enabled by default in `config.h`, to reduce footprint. Although the default configuration of the standalone edition puts more emphasis on maintaining interoperability with old peers, the Mbed OS edition only enables the most modern ciphers and the latest version of (D)TLS. - -* The following components of Mbed TLS are disabled in the Mbed OS edition: `net_sockets.c` and `timing.c`. This is because Mbed OS includes its own equivalents. - -### Help and support - -For further documentation and help, you can visit the [Mbed TLS website](https://tls.mbed.org/), which contains full documentation of the library, including function-by-function descriptions, knowledge base articles and blogs. Additionally, you can join our [support forum](https://forums.mbed.com/c/mbed-tls) for questions to the community or to help others. - -### Contributing to the project - -We gratefully accept bug reports and contributions from the community. Contributions should be submitted to the [standalone Mbed TLS project](https://github.com/ARMmbed/mbedtls), not to the version of Mbed TLS embedded within Mbed OS. - -Please see the [contributing guidelines](https://github.com/ARMmbed/mbedtls/blob/development/CONTRIBUTING.md) of the project for details on how to do this. diff --git a/features/mbedtls/VERSION.txt b/features/mbedtls/VERSION.txt deleted file mode 100644 index 4961d31..0000000 --- a/features/mbedtls/VERSION.txt +++ /dev/null @@ -1 +0,0 @@ -mbedtls-2.22.0 diff --git a/features/mbedtls/apache-2.0.txt b/features/mbedtls/apache-2.0.txt deleted file mode 100644 index d645695..0000000 --- a/features/mbedtls/apache-2.0.txt +++ /dev/null @@ -1,202 +0,0 @@ - - Apache License - Version 2.0, January 2004 - http://www.apache.org/licenses/ - - TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION - - 1.

That way, you can encrypt at most - * 2**32 messages of up to 2**32 blocks each with the same key. - * - * The per-message nonce (or information sufficient to reconstruct - * it) needs to be communicated with the ciphertext and must be unique. - * The recommended way to ensure uniqueness is to use a message - * counter. - * - * Note that for both stategies, sizes are measured in blocks and - * that a Blowfish block is 8 bytes. - * - * \warning Upon return, \p stream_block contains sensitive data. Its - * content must not be written to insecure storage and should be - * securely discarded as soon as it's no longer needed. - * - * \param ctx The Blowfish context to use. This must be initialized - * and bound to a key. - * \param length The length of the input data in Bytes. - * \param nc_off The offset in the current stream_block (for resuming - * within current cipher stream). The offset pointer - * should be \c 0 at the start of a stream and must be - * smaller than \c 8. It is updated by this function. - * \param nonce_counter The 64-bit nonce and counter. This must point to a - * read/write buffer of length \c 8 Bytes. - * \param stream_block The saved stream-block for resuming. This must point to - * a read/write buffer of length \c 8 Bytes. - * \param input The input data. This must be a readable buffer of - * length \p length Bytes. - * \param output The output data. This must be a writable buffer of - * length \p length Bytes. - * - * \return \c 0 if successful. - * \return A negative error code on failure. - */ -int mbedtls_blowfish_crypt_ctr( mbedtls_blowfish_context *ctx, - size_t length, - size_t *nc_off, - unsigned char nonce_counter[MBEDTLS_BLOWFISH_BLOCKSIZE], - unsigned char stream_block[MBEDTLS_BLOWFISH_BLOCKSIZE], - const unsigned char *input, - unsigned char *output ); -#endif /* MBEDTLS_CIPHER_MODE_CTR */ - -#ifdef __cplusplus -} -#endif - -#endif /* blowfish.h */ diff --git a/features/mbedtls/inc/mbedtls/bn_mul.h b/features/mbedtls/inc/mbedtls/bn_mul.h deleted file mode 100644 index 163869a..0000000 --- a/features/mbedtls/inc/mbedtls/bn_mul.h +++ /dev/null @@ -1,940 +0,0 @@ -/** - * \file bn_mul.h - * - * \brief Multi-precision integer library - */ -/* - * Copyright (C) 2006-2015, ARM Limited, All Rights Reserved - * SPDX-License-Identifier: Apache-2.0 - * - * Licensed under the Apache License, Version 2.0 (the "License"); you may - * not use this file except in compliance with the License. - * You may obtain a copy of the License at - * - * http://www.apache.org/licenses/LICENSE-2.0 - * - * Unless required by applicable law or agreed to in writing, software - * distributed under the License is distributed on an "AS IS" BASIS, WITHOUT - * WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. - * See the License for the specific language governing permissions and - * limitations under the License. - * - * This file is part of mbed TLS (https://tls.mbed.org) - */ -/* - * Multiply source vector [s] with b, add result - * to destination vector [d] and set carry c. - * - * Currently supports: - * - * .

No explicit IV is contained - * in an encrypted record. The IV for the first record is extracted - * at key extraction time. In contrast, for TLS 1.1 and 1.2, no - * IV is generated at key extraction time, but every encrypted - * record is explicitly prefixed by the IV with which it was encrypted. - * - AEAD transformations ([D]TLS versions >= 1.2 only) - * These come in two fundamentally different versions, the first one - * used in TLS 1.2, excluding ChaChaPoly ciphersuites, and the second - * one used for ChaChaPoly ciphersuites in TLS 1.2 as well as for TLS 1.3. - * In the first transformation, the IV to be used for a record is obtained - * as the concatenation of an explicit, static 4-byte IV and the 8-byte - * record sequence number, and explicitly prepending this sequence number - * to the encrypted record. In contrast, in the second transformation - * the IV is obtained by XOR'ing a static IV obtained at key extraction - * time with the 8-byte record sequence number, without prepending the - * latter to the encrypted record. - * - * In addition to type and version, the following parameters are relevant: - * - The symmetric cipher algorithm to be used. - * - The (static) encryption/decryption keys for the cipher. - * - For stream/CBC, the type of message digest to be used. - * - For stream/CBC, (static) encryption/decryption keys for the digest. - * - For AEAD transformations, the size (potentially 0) of an explicit, - * random initialization vector placed in encrypted records. - * - For some transformations (currently AEAD and CBC in SSL3 and TLS 1.0) - * an implicit IV. It may be static (e.g. AEAD) or dynamic (e.g. CBC) - * and (if present) is combined with the explicit IV in a transformation- - * dependent way (e.g. appending in TLS 1.2 and XOR'ing in TLS 1.3). - * - For stream/CBC, a flag determining the order of encryption and MAC. - * - The details of the transformation depend on the SSL/TLS version. - * - The length of the authentication tag. - * - * Note: Except for CBC in SSL3 and TLS 1.0, these parameters are - * constant across multiple encryption/decryption operations. - * For CBC, the implicit IV needs to be updated after each - * operation. - * - * The struct below refines this abstract view as follows: - * - The cipher underlying the transformation is managed in - * cipher contexts cipher_ctx_{enc/dec}, which must have the - * same cipher type. The mode of these cipher contexts determines - * the type of the transformation in the sense above: e.g., if - * the type is MBEDTLS_CIPHER_AES_256_CBC resp. MBEDTLS_CIPHER_AES_192_GCM - * then the transformation has type CBC resp.

This is the basic idea of [3]. - * - * - More generally, even if x[i+1] != 0, we can first transform the sum as - * .. - 2^i S[x[i]] + 2^{i+1} ( S[x[i]] + S[x[i+1]] ) + 2^{i+2} S[x[i+2]] .., - * and then replace S[x[i]] + S[x[i+1]] = S[x[i] ^ x[i+1]] + 2 S[x[i] & x[i+1]]. - * Performing and iterating this procedure for those x[i] that are even - * (keeping track of carry), we can transform the original sum into one of the form - * S[x'[0]] +- 2 S[x'[1]] +- .. +- 2^{d-1} S[x'[d-1]] + 2^d S[x'[d]] - * with all x'[i] odd. It is therefore only necessary to know S at odd indices, - * which is why we are only computing half of it in the first place in - * ecp_precompute_comb and accessing it with index abs(i) / 2 in ecp_select_comb. - * - * - For the sake of compactness, only the seven low-order bits of x[i] - * are used to represent its absolute value (K_i in the paper), and the msb - * of x[i] encodes the sign (s_i in the paper): it is set if and only if - * if s_i == -1; - * - * Calling conventions: - * - x is an array of size d + 1 - * - w is the size, ie number of teeth, of the comb, and must be between - * 2 and 7 (in practice, between 2 and MBEDTLS_ECP_WINDOW_SIZE) - * - m is the MPI, expected to be odd and such that bitlength(m) <= w * d - * (the result will be incorrect if these assumptions are not satisfied) - */ -static void ecp_comb_recode_core( unsigned char x[], size_t d, - unsigned char w, const mbedtls_mpi *m ) -{ - size_t i, j; - unsigned char c, cc, adjust; - - memset( x, 0, d+1 ); - - /* First get the classical comb values (except for x_d = 0) */ - for( i = 0; i < d; i++ ) - for( j = 0; j < w; j++ ) - x[i] |= mbedtls_mpi_get_bit( m, i + d * j ) << j; - - /* Now make sure x_1 .. x_d are odd */ - c = 0; - for( i = 1; i <= d; i++ ) - { - /* Add carry and update it */ - cc = x[i] & c; - x[i] = x[i] ^ c; - c = cc; - - /* Adjust if needed, avoiding branches */ - adjust = 1 - ( x[i] & 0x01 ); - c |= x[i] & ( x[i-1] * adjust ); - x[i] = x[i] ^ ( x[i-1] * adjust ); - x[i-1] |= adjust << 7; - } -} - -/* - * Precompute points for the adapted comb method - * - * Assumption: T must be able to hold 2^{w - 1} elements. - * - * Operation: If i = i_{w-1} ... i_1 is the binary representation of i, - * sets T[i] = i_{w-1} 2^{(w-1)d} P + ... + i_1 2^d P + P. - * - * Cost: d(w-1) D + (2^{w-1} - 1) A + 1 N(w-1) + 1 N(2^{w-1} - 1) - * - * Note: Even comb values (those where P would be omitted from the - * sum defining T[i] above) are not needed in our adaption - * the comb method.

    • - *
  • Montgomery: y^2 = x^3 + A x^2 + x mod P (Curve25519, - * Curve448)
- * In both cases, the generator (\p G) for a prime-order subgroup is fixed. - * - * For Short Weierstrass, this subgroup is the whole curve, and its - * cardinality is denoted by \p N. Our code requires that \p N is an - * odd prime as mbedtls_ecp_mul() requires an odd number, and - * mbedtls_ecdsa_sign() requires that it is prime for blinding purposes. - * - * For Montgomery curves, we do not store \p A, but (A + 2) / 4, - * which is the quantity used in the formulas. Additionally, \p nbits is - * not the size of \p N but the required size for private keys. - * - * If \p modp is NULL, reduction modulo \p P is done using a generic algorithm. - * Otherwise, \p modp must point to a function that takes an \p mbedtls_mpi in the - * range of 0..2^(2*pbits)-1, and transforms it in-place to an integer - * which is congruent mod \p P to the given MPI, and is close enough to \p pbits - * in size, so that it may be efficiently brought in the 0..P-1 range by a few - * additions or subtractions. Therefore, it is only an approximative modular - * reduction. It must return 0 on success and non-zero on failure. - * - */ -typedef struct mbedtls_ecp_group -{ - mbedtls_ecp_group_id id; /*!< An internal group identifier. */ - mbedtls_mpi P; /*!< The prime modulus of the base field. */ - mbedtls_mpi A; /*!< For Short Weierstrass: \p A in the equation.
