Integrate TF-M and PSA Crypto API with PUFcc

by Andy Chen

Hi TF-M 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-M. However, there are multiple versions included, and we need your assistance for specification clarification. Please ensure the versions match your recommendations. For TF-M, we plan to integrate with: TF-M v2.1.0 PSA Crypto API - v1.1.0 PSA Certified APIs Architecture Test Suite - v1.6 TF-M 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-M , scripts or details with the ARM hardware That would be grateful. 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:983ad4d1-6d7d-4acb-a22d-5a49b94594d4] 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-M. Thank you very much!!! Have a Nice Day, Andy [cid:2fcb4633-c50b-4a64-8161-c5020f3b1ad3] 熵碼科技股份有限公司 Tel: 886-3-5601010 #2119 Email: andychen(a)pufsecurity.com<mailto:andychen@pufsecurity.com> Website: https://www.pufsecurity.com/ -------- Disclaimer: This e-mail is from PUFsecurity Corporation.

Suggestion for unified logging library

by Jackson Cooper-Driver

Hi all, I would like to propose a unified logging library in TF-M. The primary aim of this is to combine the fragmented logging we have across TF-M into a single logging library, with a single top-level API. Currently, different components (BL1, SPM, secure partition, etc.) have different logging APIs and these also have different underlying implementations. Some call directly into the UART output string function and others call printf. Sometimes using one logging API in a different component leads to build failures, or nothing ending up on the UART at all. The primary aim here is for users to be able to use the same API throughout TF-M and for it to always work. This API will naturally be split into different logging levels, with build configuration controlled whether or not the string is actually output. Note that the underlying implementation can be different for different components - there can be hooks within the library which allow components to specify how they want to output the string. Initially, these can be used to maintain the existing underlying implementation. In the longer term, however, it would be useful to unify the underlying implementation also whether that be by using printf or with our own custom printf format parser. Please let me know any thoughts or concerns about the above suggestion. Thanks, Jackson

RFC: Remove specific section for psa_interface_thread_fn_call

by Nicola Mazzucato

Hi All, I pushed for review a Request For Comments (RFC) patch where I remove specific attributes for sections introduced a while ago. At that time, it was fixing an issue with Armclang builds. However it has been noticed that with GCC, those functions are not placed within the .text section, as otherwise expected. With the proposed RFC patch https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/29755, I ran a few tests and builds and the "old" issue with Armclang does not appear anymore and the functions are correctly placed within the .text section. I would like to ask the community to cherry pick the patch and build & run their tests, to further verify that we are not breaking anything else. If no issues are reported in a week or so, I will remove the RFC and then the patch will go through the final review. Many thanks in advance for your cooperation.

Question about random number g

by Zhang, Hao

Hi TF-M and mbedtls community, I am new to TF-M, I have a few questions about CryptoCell and random number generation. Thank you in advance. 1. I figure there seems to have two CryptoCell 312 implementations within TF-M. One under lib/ext/cryptocell-312-runtime and the other under platform/ext/accelerator/cc312/cc312-rom. What are the difference between these two? 2. For lib/ext/cryptocell-312-runtime, it does not define MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG whereas /ext/accelerator/cc312/cc312-rom does. Does that mean cryptocell-312-runtime is initiating RNG cryptodriver by using mbedtls_entropy_add_source whereas cc312-rom is using mbedtls_psa_external_get_random<https://github.com/zephyrproject-rtos/trusted-firmware-m/blob/8df9cc8baf462…>. If so, may I ask why these two cryptocells take two different approaches? I read from one of the documentation that mbedtls_psa_external_get_random is used when entropy is sufficient. So if entropy is sufficient, is it always preferred to have MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG defined and implements mbedtls_psa_external_get_random? What are the differences between the two approaches. 3. I also found cryptocell-312-runtime defines the entry point function cc3xx_init_random<https://github.com/zephyrproject-rtos/trusted-firmware-m/blob/8df9cc8baf462…>. But since PSA random number entry point funciton is not complete, the cc3xx_init_random is not being called anywhere, right? [https://opengraph.githubassets.com/17cdebc400b0ed807c620b586b21f3f77ff9c5d3…]<https://github.com/zephyrproject-rtos/trusted-firmware-m/blob/8df9cc8baf462…> trusted-firmware-m/platform/ext/accelerator/cc312/cc312-rom/psa_driver_api/src/cc3xx_psa_random.c at 8df9cc8baf46252fd188bba1d87333a8daa9a5e8 · zephyrproject-rtos/trusted-firmware-m<https://github.com/zephyrproject-rtos/trusted-firmware-m/blob/8df9cc8baf462…> Zephyr repository tracking https://git.trustedfirmware.org/trusted-firmware-m.git/ - zephyrproject-rtos/trusted-firmware-m github.com 4. I know random number generation PSA entry point function is in development, may I ask when that would be expected to complete? Thank you very much! Best regards, Hao

Re: Firmware Update: Storage Failure While Rejecting a Staged Image

by Cedric Klikpo

Hi Maulik, Thanks for your support. 1. I think I understand why you don’t get the error on the Musca-B1. In fact, we are not using the same flash driver: 1.1. My build uses the `emulated_flash_dvr`, which checks that the byte is erased in flash before attempting a write (this is where I get the error). 1.2. The Musca-B1 platform uses the `qspi_ip6514e_drv`, which does not perform such a check before writing to the flash. From what I understand, the MT25QL Series Flash NOR does not return an error even if you try to write a 1 in a bit that was 0. As such, you do not encounter the error. 2. It is strange that you don’t get the warning when MCUBOOT_CONFIRM_IMAGE=OFF. Best regards, Cédric

However, the test is marked as passed with the following warning, which clearly states that the testcase is skipped: ``` Executing 'TFM_NS_FWU_TEST_1001' Description: 'Functionality test.'

Re: Firmware Update: Storage Failure While Rejecting a Staged Image

by Maulik Patel

Hello Cedric Unfortunately we only have musca b1 support for FWU at the moment. However as you mentioned, I did try TFM version 1.8.0 on commit *35ac80c85 and all tests (secure and non-secure including FWU) passes without any issues. Best Regards, Maulik
