Re: [TF-M] Questions on Musca-B1 SE implementation

by Tamas Ban

Hi Suresh, Here is a link how to build images to Musca-B1 SE: https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git/tree/platform/e… I have built with GCC and MinSizeRel build type: Profile Medium: Memory region Used Size Region Size %age Used FLASH: 101464 B 381 KB 26.01% RAM: 61304 B 64 KB 93.54% [100%] Built target tfm_s Profile Large: Memory region Used Size Region Size %age Used FLASH: 170448 B 381 KB 43.69% RAM: 62980 B 64 KB 96.10% [ 97%] Built target tfm_s The profiles means different capabilities of TF-M, they were introduced to support constrained devices as well, with limited capability. There is a detailed description about the profiles here: https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git/tree/docs/techn… BR, Tamas From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Suresh Marisetty via TF-M Sent: 2021. április 29., csütörtök 21:49 To: tf-m(a)lists.trustedfirmware.org Subject: [TF-M] Questions on Musca-B1 SE implementation I am following up on a question that came up on the TFM Core and MCUBoot image sizes that is built for SE on Musca-B1. We are trying to figure out the resource requirements for SE, to be able to host the TF-M as suggested in the slides below. Wondering if anyone throw more light on the RAM/FLASH requirements for it. Also, does the TFM profile small/medium/large map to this at all or is it different from them. Also, what's are the estimated latencies of boot on SE with all the Flash accesses, etc. https://www.trustedfirmware.org/docs/Musca-B1-Secure-Enclave-Solution.pdf https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git/tree/platform/e… Any info on this would be appreciated. thanks Suresh Marisetty Infineon Semiconductor Corporation

Security vulnerability notice - abort() function may not take effect in TF-M Crypto multi-part operations

by David Wang

Hi Everyone, This email is a notification of a new security vulnerability reported to TF-M. It's about the Crypto service in TF-M - abort() function may not take effect in TF-M Crypto multi-part MAC/hashing/cipher operations. Please check the details in the security advisory attached. (.rst version is coming soon) The fix has been merged on the latest master branch - Crypto: Remove unnecessary multi-part operation clean-up (I9cd0fa38) * Gerrit Code Review (trustedfirmware.org)<https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/9932> We're planning a hot fix release. Will share the plan with you when it's ready. Thanks. Regards, David Wang ARM Electronic Technology (Shanghai) Co., Ltd Phone: +86-21-6154 9142 (ext. 59142)

[RFC] Overall Secure Partition Management (SPM) design document

by Ken Liu

Hi everyone, SPM came at the begging of the project, so the design document was spread into several small pieces as features. Now it is a chance to provide an overall document as we are going to have significant feature updates for FFM 1.1. Here is the draft of the design document: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/9928 This document is trying to address the overall design for 1.1 much. It based on FFM 1.1 update alpha stage document. Several points: * I want to publish this document public earlier for a quick taste, even though some features are not introduced yet (such as MMIOVEC), so there defecation would be some missing items, and I would keep updating recently. * Meanwhile, I would collect feedbacks from you and update them into the design document, too. * Prototype would be performed to see the situation. * In this document I am trying to tell the conclusion directly instead of go over the conceptual items described in FF-M. If you can not find background either in this document or in the specification please tell me, I would try to add the missing part. Or if you think some text is quite redundant, tell me and I would remove the without hesitation. The 1.1 specification (alpha): https://developer.arm.com/documentation/aes0039/latest Please provide your feedback - both mailing list and patch are welcome (in the patch is more welcome, as there may be long discussions so patch comment is easier to be tracked). Thanks! /Ken

Re: [TF-M] Timeframe on release/approval

by Kevin Townsend

Hi Shebu, Just as a FYI TF-M 1.3 has already been integrated into Zephyr and will be part of the 2.6.0 release, scheduled for the end of the month. If TF-M 1.4 happens in July, that will likely be the version that Zephyr 2.7.0 will likely use, which will be an LTS release.

Re: [TF-M] [FIH lib] : fih question on a specific fault injection

by Raef Coles

I think at the moment that wouldn't get caught by the flow control countermeasures. However, we did have an idea for an improvement (which didn't get implemented), that should resolve it. At the moment, calling a function with FIH_CALL increases the flow control counter by 1. The alternative we considered was to instead increase the counter by a value that was generated based on the function that was called. Exactly how to generate this number is tricky, since we can't really implement a proper hash function in the preprocessor. The compromise we came to was that we could increase it by sizeof(__func__), (the length of the function name). This is accessible to both the call and the ret, and should be reasonably easily implementable. This wouldn't solve your issue immediately, but one function could then be renamed to be of different length. Another alternative is that you could manually increment and check the flow-control counter, though having to do that manually isn't ideal. Do either of these options seem reasonable?
