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

by David Hu

Hi @Mark Horvath<mailto:Mark.Horvath@arm.com>, Could you please help take a look at the following questions about Musca-B1 SE? Thanks 😊 Best regards, Hu Ziji From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Suresh Marisetty via TF-M Sent: Thursday, May 13, 2021 6:04 AM To: Tamas Ban <Tamas.Ban(a)arm.com>; tf-m(a)lists.trustedfirmware.org Cc: nd <nd(a)arm.com> Subject: Re: [TF-M] Questions on Musca-B1 SE implementation Hi Tamas, The following is good information. A few questions: 1. Is it correct to state that for the SE, the PSA RoT services do not have any software Crypto implementation, but leverage from CC-312? 2. What is the size of the TFM on the host (M33) with only PSA RoT service proxy with redirection to SE 3. Just trying to understand the TFM image size requirements on M33 vs. SE 4.

Factory provisioning with tf-m

by Edward Yang

Hi, I would like to know about how to use tf-m with factory provisioning,for example,HUK,IAK,ROTPK these ROT assets should be injected to device via factory provisioning,besides,application specific certificates and private keys can also be injected during this procedure,in tf-m roadmap,there is a provision service,what's the functionality of this service? In initial attestation service, attest_register_initial_attestation_key() calls tfm_plat_get_symmetric_iak() to get IAK, I found implementation template of tfm_plat_get_symmetric_iak() just copys hardcoded key value(for developer mode). I think this is not allowed in production mode.Is there any recommended implementation of this API? What if I stored IAK in a specific address of MCU embedded flash during factory provisioning, such as #define IAK_REGION IAK_base_addr in flash_layout.h,and then use flash.read get the key value？ tfm_plat_get_symmetric_iak( ) { TFM_HAL_ITS_FLASH_DRIVER.ReadData(IAK_REGION, buff, size); } Best Regards, Poppy Wu Macronix Microelectronics (Suzhou) Co.,Ltd Http: //www.mxic.com.cn ============================================================================ CONFIDENTIALITY NOTE: This e-mail and any attachments may contain confidential information and/or personal data, which is protected by applicable laws.

Hi, I would like to see if there is any guidance/documentation on how to coordinate between the firmware update services API with that of MCUboot. Does the use of this API make the MCUboot update services redundant? thanks Suresh Marisetty Infineon Semiconductor Corporation Lead Member of Technical Staff CYSC CSS ICW SW SSE Mobile: +5103863997 Suresh.Marisetty(a)infineon.com<mailto:Suresh.Marisetty@infineon.com>

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

Since you are contributing a new platform, I would recommend that you read the Trusted Firmware maintenance process<https://developer.trustedfirmware.org/w/collaboration/project-maintenance-p…>, for further details on the process. To answer your questions about the timeframe, that really depends on various factors, such as how busy the maintainers of this code are, weather there is a release pending which would follow a code freeze, and how complicated the changes are. I don't believe it is easy to estimate a figure.
