Request for comments on TF-M Profile Small design updates

by David Hu

Hi all, Hope you are doing well. May I ask for your review on the latest Profile Small design? The design has been updated with following major changes: * The default AES mode is changed to CCM mode from CBC mode, to achieve more secured connection. * More details on the use case of Profile Small Please review the document on https://review.trustedfirmware.org/c/trusted-firmware-m/+/3598. Please feel free to comment. Thank you! The patch set is updated as well, following the latest design. Please check it on https://review.trustedfirmware.org/q/topic:%22profile-s-config%22+(status:o…. Compared with previous versions, CCM is supported and some configurations are selected to optimize the Crypto memory footprint. Best regards, Hu Ziji

Re: [TF-M] Will TFM crypto service suppot national encryption algorithm in the future?

by Shebu Varghese Kuriakose

Hi Matt, TF-M plans to continue using Mbedcrypto in the crypto service. Mbed Crypto implements the PSA Crypto APIs and is also now part of trustedfirmware.org community project alongside TF-M. However, it is possible with some effort for a platform using TF-M to use another crypto library in the TF-M crypto service. Of course the library will need to support PSA Crypto APIs to be PSA compliant. There is support for ARIA, Camellia in Mbed TLS. There has already been a PR for SM4 support sometime back - https://github.com/ARMmbed/mbedtls/pull/1165. SM2/SM3 algorithm support can be contributed to MbedTLS project (Mbed Crypto is now merged to Mbed TLS project). The maintainers will have to review and integrate the contribution as their bandwidth permits while finding time to review several contributions that the project is receiving. I am adding psa-crypto mailing list which is used for Mbedcrypto/PSA Crypto discussions. Regards, Shebu From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Matt via TF-M Sent: Thursday, April 16, 2020 8:24 AM To: tf-m(a)lists.trustedfirmware.org Subject: [TF-M] Will TFM crypto service suppot national encryption algorithm in the future? Hi All TFM experts, TFM crypto service is based on mbedcrypto and there is no national encryption algorithm support in current mbedcrypto implementation. The Chinese market has a strong demand for national encryption algorithms, such as SM2/SM3/SM4, will TFM crypto service change to other crypto implementation to support the national encryption algorithm in the future? Thanks, -Matt

Re: [TF-M] [TF-A] Project Maintenance Proposal for tf.org Projects

by Sandrine Bailleux

Hi all, Thanks to all who have commented on this proposal so far. I've edited the original document to try and incorporate all feedback gathered so far (through the TSC meeting, this email thread and the TF-A tech call). Please have another look and flag anything I might have missed: https://developer.trustedfirmware.org/w/collaboration/project-maintenance-p… The major changes are: == Removed concept of self-review == This is proving too controversial, several people do not want to allow self-review. Roles of maintainer and code owner are still cumulative but cannot be both exercised for the same patch. The exact method of dealing with review bottleneck is still to be decided. In addition to the current proposal of increasing the maintainers pool, the most popular alternatives mentioned so far are: - Set a minimum wait time for feedback before a patch can be merged without any further delay. - Mandate distinct reviewers for a patch. == Enhanced the section "Patch contribution Guidelines" == Mentioned that patches should be small, on-topic, with comprehensive commit messages. == Added a note about how to deal with disagreement == If reviewers cannot find a common ground, the proposal is to call out a 3rd-party maintainer. == Removed "out-of-date" platform state == Squashed it into "limited support" to reduce the number of states. == Removed "orphan" state from platform support life cycle == This concept is orthogonal to the level of functionality. Added a note in the "Code Owner" section instead. == Per-project guidelines as a complementary document == Added a list of things that it would typically cover. == Added requirement on fully supported platforms to document the features they support == == Added todo mentioning that the proposal might cover branching strategies in the future == The full diff may be seen here: https://developer.trustedfirmware.org/phriction/diff/73/?l=4&r=5 This proposal is still open for discussion at this stage and further feedback is most welcome! Regards, Sandrine
