Re: [TF-M] TF-M Technical Forum call - May 14

by Andrew Thoelke

Hi, Following on from the presentation and discussion on Ken's "Default Handles" proposal on 30 April, we have made some updates following the feedback and further implementation consideration. I (or Ken if he attends) can present an update on the proposal. I also mentioned last time that there is some missing context for this proposal. We are working on an update for PSA-FF-M v1.1 that will provide an enhancement of the v1.0 'IPC model' for secure services, and also a 'Secure Function model' which is similar to the 'library model' of TF-M today. The objective is a single architecture that enables secure service developers to select the framework features required for the complexity of the service; and the framework implementation to be optimised for simple systems. On Thursday, I would like to present an introduction to this PSA-FF-M v1.1 roadmap, and outline the steps that we think are required.

TFM 1.0 integration merged into upcoming Zephyr 2.3

by Kevin Townsend

Hi, Just as a FYI, TF-M 1.0 support was merged into Zephyr RTOS this week, meaning that it will be included by default in Zephyr starting with the upcoming 2.3 release. Zephyr is used on the non-secure side, and TF-M is used on the secure side, with the TF-M build happening as part of the normal Zephyr build process, meaning no knowledge of TF-M internals is required to get started. It's also worth highlighting QEMU integration with Zephyr+TF-M. Using the MPS2 AN521 target, you can run application from the command-line with QEMU, meaning that you can create test applications that use the PSA APIs with no HW required, or perform certain application tests purely in SW. As an example, the following sample was run with a clean install of Zephyr, showing QEMU output and demonstrating how to use the initial attestation, crypo and secure storage services: https://github.com/zephyrproject-rtos/zephyr/tree/master/samples/tfm_integr… $ mkdir zephyrtfm && cd zephyrtfm $ west init $ west update $ west build -p -b mps2_an521_nonsecure zephyr/samples/tfm_integration/psa_level_1/ -t run [INF] Starting bootloader [INF] Swap type: none [INF] Swap type: none [INF] Bootloader chainload address offset: 0x80000 [INF] Jumping to the first image slot [Sec Thread] Secure image initializing!

We hope this will make TF-M, and all the hard work that has gone into it, far more accessible to a wider range of people, with HW no longer being an immediate limitation to trying it out.

Remove 'INDIVIDUAL_SW_COMPONENTS' support from attestation

by Tamas Ban

Hi, I let you notify that 'INDIVIDUAL_SW_COMPONENTS' support is planned to be removed from attestation service and bootloader. What is this? * Boootloader and SPE can exchange data through shared memory. This is needed to provide the boot status info to attestation service. The boot status info is included in the SW_COMPONENT claim in the attestation token. * Until now two types of data encoding was supported during this data sharing: * All boot status data item is passed as a single TLV entry: -DATTEST_BOOT_INTERFACE=INDIVIDUAL_CLAIMS * Boot status is already encoded to CBOR format at build time. Bootloader only updates a few field in it, and pass the CBOR object to SPE. Then attestation service just include this already CBOR formatted object to the token, without the need to applying further encoding. -DATTEST_BOOT_INTERFACE=CBOR_ENCODED_CLAIMS The 'INDIVIDUAL_CLAIMS' format is marked as deprecated feature for a while in the code base. Now the plan is to remove it and rely fully on the 'CBOR_ENCODED_CLAIMS' format. The build system support for this is present in TF-M for a long, and recently it was upstream to original MCUBoot 'imgtool' script as well. Next MCUBoot release (v1.6) will contain it. If you has any objection, because your project is using the 'INDIVIDUAL_CLAIMS' format then please let us know! BR, Tamas
