Broken link in TFO/TF-M entry page

by Etienne CARRIERE

Hello, I've seen that the "CONTRIBUTE/SUBMIT CODE<https://tf-m-user-guide.trustedfirmware.org/contributing/contributing_proce…>" link in https://www.trustedfirmware.org/projects/tf-m/ is broken. It links to deprecated https://tf-m-user-guide.trustedfirmware.org/contributing/contributing_proce… whereas I think it should link to https://trustedfirmware-m.readthedocs.io/en/latest/contributing/contributin….

Order of starting Secure Partitions

by Florek, Bartlomiej

Hello, I'm trying to fit a new Secure Partition into Trusted Firmware - M environment. The current working environment consists of Zephyr RTOS 3.7 + TF-M 2.1.0 running under QEMU on MPS2 AN521 platform. General skeleton is in place - manifest with dependencies on TFM_CRYPTO, interface, IPC and handling communication. However, I have problems with using the PSA Crypto from the aforementioned new Service. I need a hash function, so I thought I'd use PSA Crypto API. The problem is that either the hash function or the initialization function (psa_crypto_init) is returning error (PSA_ERROR_INSUFFICIENT_MEMORY). I discovered that logs show PSA Crypto partition is loading after mine. This problem occurs in the entry_point function. Is it possible to change the order of partitions loading or is there different mechanism advised to synchronize partition loading? Thank you in advance for your suggestions. Best regards, Bartlomiej

Planned outages

by Matthew Dalzell

Hi all, There are some planned outages for Friday morning (30th May UK around 10AM BST) to our CI. This will affect the review process for a short period of time, expected to be less than one hour, but may cause some disruption over the weekend too. I will be sure to send out another message once things have settled and should be back to normal. Thank you for your patience and apologies in advance for any issues which may arise, Matt

Issue building docs

by Bohdan.Hunko＠infineon.com

Hi all, I am trying to build docs with following commands: cmake -S docs -B ./build_docs cmake --build build_docs/ -- tfm_docs_userguide_pdf But I get following error resolving references... failed Warning, treated as error: RSVG converter command 'rsvg-convert' cannot be run. Check the rsvg_converter_bin setting When I remove -W (warnings are errors) option from COMMAND "${SPHINX_EXECUTABLE}" -W -b html -j 1 -c ${SPHINXCFG_CONFIG_PATH} ${SPHINXCFG_SOURCE_PATH} "${SPHINXCFG_OUTPUT_PATH}/html" In docs/CMakeLists.txt then docs builds fine. Is this -W option intentional? Should this issue be fixed or -W removed?

PSA_IOT_PROFILE_1 attestation Certification Reference

by Quach, Brian

Hi, Per https://datatracker.ietf.org/doc/html/draft-tschofenig-rats-psa-token-07 (which is latest spec I can find for profile 1 token): The Certification Reference claim is used to link the class of chip and PSA RoT of the attesting device to an associated entry in the PSA Certification database. It MUST be represented as a thirteen-digit [EAN-13<https://www.gs1.org/standards/barcodes/ean-upc>].¶<https://datatracker.ietf.org/doc/html/draft-tschofenig-rats-psa-token-07#se…> Linking to the PSA Certification entry can still be achieved if this claim is not present in the token by making an association at a Verifier between the reference value and other token claim values - for example, the Implementation ID.¶<https://datatracker.ietf.org/doc/html/draft-tschofenig-rats-psa-token-07#se…> psa-certification-reference-type = text .regexp "[0-9]{13}" psa-certification-reference = ( ? psa-certification-reference-key => psa-certification-reference-type ) But in the tf-m-tools repo: iat-verifier\iatverifier\psa_iot_profile1_token_claims.py it checks for PSA 2.0 profile HW version which is EAN-13 + 5. class HardwareVersionClaim(AttestationClaim): """Class representing a PSA Attestation Token Hardware version claim""" def verify(self, token_item): self._check_type('HARDWARE_VERSION', token_item.value, str) value_len = len(token_item.value) expected_len = 19 # 'EAN13-Version' 13 + 1 + 5. e.g.:0604565272829-10010 if len(token_item.value) != expected_len: msg = 'Invalid HARDWARE_VERSION length; must be {} characters, found {} characters' self.verifier.error(msg.format(expected_len, value_len)) for idx, character in enumerate(token_item.value): if character not in string.digits: if idx != 13 or character not in '-': msg = 'Invalid character {} at position {}' self.verifier.error(msg.format(character, idx+1)) It seems like this was changed 3yrs ago: SHA-1: 8ac8d17d15353c7f7933ae8065646946ae47f993 * Fix HW Version claim expected length www.psacertified.org issuing HW versions of format '[0-9]{13}-[0-9]{5}'.

Internal Trusted Storage

by Michael Khoyilar

Hi team, Can you help me with this statement that "Currently, the TF-M Secure Storage service implements PSA Protected Storage version 1.0-beta2. There is not yet an implementation of PSA Internal Trusted Storage in TF-M." Our SoC does NOT have internal flash, but we have OTP where we keep the confidential data. Can you help how to handle this ITS situation. I wonder if PSA level-2 certification requires ITS? Thanks BR Michael

Re: [EXTERNAL] Re: Attestation calls to PSA Crypto

by Quach, Brian

Hi Antonio, I figured it out. I wasn’t including secure_fw/partitions/crypto/tfm_mbedcrypto_include.h properly so attestation was linking directly to the PSA Crypto function implementation instead of the client interface. I’m surprised it did not complain about a symbol collision without having the mbedcrypto__ prefix. The PSA crypto API implementation source files were “PRIVATE” so I’m not sure how attestation was able to link to them at all.

Attestation calls to PSA Crypto

by Quach, Brian

Hi, Assuming Isolation Level 1 and IPC backend, I'm using Attestation partition with SFN model with stateless handle and a custom Crypto partition using IPC model with stateless handle. My custom Crypto partition includes a PSA crypto wrapper which defines all the PSA Crypto APIs to use HW crypto. We used IPC since we want to be able to support isolation level 2-3 in the future. When the Attestation partition make calls to PSA Crypto (psa_hash_setup for example), should it use a psa_call() to the Crypto Partition? That is what I had expected since the crypto partition is IPC model but I'm seeing it call the PSA crypto code directly. Also, it appears to provide client side psa_hash_operation_t directly to the psa_hash_setup which is expecting the full operation struct. Is my configuration valid? How should it work?
