Hi Andy
Please see my replies inline. Adding Jothikumar Mani for PSA Certified APIs Architecture Test Suite.
Thanks, Manish Badarkhe

Hi TF-A teams,
This is Andy from PUFsecurity, and we have a project with ARM. We try to integrate the PSA Crypto API with PUFcc (Our Crypto Engine) on TF-A. However, there are multiple versions included, and we need your assistance for specification clarification.
Please ensure the versions match your recommendations.
For TF-A, we plan to integrate with: TF-A lts-v2.10.5 PSA Crypto API - v1.1.0 PSA Certified APIs Architecture Test Suite - v1.6 [MB]: This looks fine. As TF-A lts-v2.10.5 using mbedTLS v3.6.0 which is compliance with PSA Crypto API - v1.1.0 but mbedTLS team can provide more detailed answer on this and also on test suite PSA Certified APIs Architecture Test Suite - v1.6.
TF-A It would be beneficial to use the same hardware (FPGA) and tools as the ARM development team. If we can confirm which models are used for TF-A , scripts or details with the ARM hardware That would be grateful.
[MB]: We are using FVP AEM model i.e. FVP_Base_RevC-2xAEMvA (Model version: 11.26, Build: 11). Test Run with PSA Crypto you can find here: https://ci.trustedfirmware.org/job/tf-a-builder/4029201/ (today's daily run)
PSA Crypto API - The test bench is using the PSA Crypto API v1.1.0, and it is published in 2022. And Now is v1.2.1 in March 2024. I not sure it is a good choose or not. [cid:0e747007-8c2a-49a7-9447-8d5e7f9a3e9c]
[MB]: It looks like arch-test is not upgraded to use v1.2.1 PSA Crypto API. Added Jothikumar Mani, he may have idea about this.
Test Bench - For the "PSA Certified APIs Architecture Test Suite - v1.6," we would like to identify which test codes (test_c001 to test_c067) are relevant for TF-A.
[MB]: Again, TF-A is not using this test suite, so we don't have any insights unless we review all these tests. TF-A mainly uses the following PSA_* APIs for signature verification, hash calculation, and hash comparison.
psa_crypto_init mbedtls_md_psa_alg_from_type psa_set_key_algorithm psa_set_key_type psa_set_key_usage_flags psa_import_key psa_destroy_key psa_verify_message psa_hash_compute psa_hash_compare
Thank you very much!!!
Have a Nice Day, Andy
