Notice of refactoring of C11 and Unix-like platform adherence

by Gilles Peskine

Hello, In the next release of TF-PSA-Crypto 1.1.0 and Mbed TLS 4.1.0, we have made significant changes to code that detects features that are not part of C99 proper. The changes are mainly: * Uniformization of POSIX/Unix feature detection macros. * Assume a C99-compliant printf (dropping hacks for ancient MSVC and forcing compliant printf on MinGW). * Expansion of “static assert” in C99 when an official C11 static_assert isn't available. We believe the new code to be standards-compliant, however it may break the build on some platforms that are not strictly POSIX compliant or cause some new compiler warnings. If you use TF-PSA-Crypto or Mbed TLS on a “less mainstream” Unix-like platform, or with a compiler that isn't GCC or Clang, and the break builds for you, please open a pull request with the necessary fixes (probably in core/tf_psa_crypto_platform_requirements.h, core/tf_psa_crypto_common.h, or library/mbedtls_platform_requirements.h). We have also made some minor changes in the Mbed TLS 3.6 long-time support branch. They are significantly less expansive, but may affect platforms that are mostly Linux-like but are not Linux or are using an unusual libc. Best regards, -- Gilles Peskine TF-PSA-Crypto and Mbed TLS developer

ECDH and key interfaces on development branch

by Leonie Reichert

Dear MbedTLS contributors, I'm reaching out with a question regarding the ECDH and similar interfaces on the MbedTLS development branch. I hope this mailing list is the appropriate venue for this discussion. I am preparing a pull request for an implementation of the Hybrid Public Key Encryption (HPKE) standard for MbedTLS/TF-PSA-Crypo. It seems like the development branch at TF-PSA-Crypo does not seem to support ecdh.h anymore. While this is not seem to be explicitly stated anywhere, there are instructions on how to use the PSA interface instead to create ECDH keys. Now my question: So the my code meets the desired quality criteria, does all other key interfaces also have to be changed? I am using the ECP interface a lot, so mbedtls_ecp_group_init, mbedtls_ecp_point_init, mbedtls_ecp_keypair_init and so on. The functions are still available but the instructions in psa_tranistion.md in Section "translating a legacy ephemeral key agreement TLS server workflow" make me believe that using non-psa key interfaces might be undesirable in MbedTLS in general. I would greatly appreciate any clarification on this matter.

Do not hesitate if you need any other information. I'm new to cryptography and currently learning TLS with mbedTLS. Thanks in advance, Adrien.

Performance Inquiry- High read/write latency observed in Mbedtls 3.6.2 (DTLS)

by Ankita Hatmode

Hi Team, We are working on an embedded security project using MbedTLS 3.6.2 for DTLS communication. As part of our performance evaluation, we analyzed the timing metrics for DTLS handshake and application data read/write operations. During testing, we observed that the time taken for data read and write operations is significantly higher than expected. [image: image.png] We would appreciate your guidance on the following: 1. What factors in MbedTLS could contribute to higher read/write latency? 2. Are there any known performance limitations or configuration settings that impact DTLS data transfer timing? 3. Are there recommended optimizations for embedded platforms to improve throughput? Please let us know if any more info is required. Looking forward to your response.
