Hello Suresh:

How are you? I hope all is well with you!

Virtual Linaro Connect Fall is next week and there is a presentation relevant to your question along with some others. As an online event, it is free registration and I am listing here below a few sessions that might be of interest to you related to security and AI inferencing for microcontrollers:

LVC21F-116 Assessing the effectiveness of MCUBoot protections against fault injection attacks

LVC21F-112 Picolibc: A C Library for Smaller Systems

https://events.pinetool.ai/2231/#sessions/67136?referrer%5Bpathname%5D=%2Fsessions&referrer%5Bsearch%5D=&referrer%5Btitle%5D=Sessions

LVC21F-303 Secure Sensor Data Pipeline

https://events.pinetool.ai/2231/#sessions/67174?referrer%5Bpathname%5D=%2Fsessions&referrer%5Bsearch%5D=&referrer%5Btitle%5D=Sessions

LVC21F-312 TrustedFirmware.org panel discussion

https://events.pinetool.ai/2231/#sessions/67183?referrer%5Bpathname%5D=%2Fsessions&referrer%5Bsearch%5D=&referrer%5Btitle%5D=Sessions

LVC21F-319 TVM for micro targets

https://events.pinetool.ai/2231/#sessions/67190?referrer%5Bpathname%5D=%2Fsessions&referrer%5Bsearch%5D=&referrer%5Btitle%5D=Sessions

I thought you may be interested in the AI as well since there are security implications for trusted AI.

All the best!

Subject: Re: [TF-M] TF-M v1.3.0 release - Fault Injection and DPA in line with PSA L3 Certification

Hi,

I have a question related to the PSA L3 certification and the requirement to support Side-channel and fault injection attacks.

I have noted that TFM and MCUBoot does implement some software countermeasures for Fault Injection. However, I am wondering if there is similar implementation support for the Crypto Lib in TFM (or Mbed TLS) with software counter measures for side channel DPA.

Needless to say, there are some known best practices for DPA software countermeasures.

thanks

Hello,

TF-M project released version v1.3.0, tagged as TF-Mv1.3.0.

Please take a look into the release notes for the new features and changes:

https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git/tree/docs/reference/releases/1.3.0.rst

The major features:

Support stateless RoT Service defined in FF-M 1.1
Support Second-Level Interrupt Handling (SLIH) defined in FF-M 1.1
Add Firmware Update (FWU) secure service, following Platform Security Architecture Firmware Update API
Migrate to Mbed TLS v2.25.0
Update MCUboot version to v1.7.2
Add a TF-M generic threat model
Implement Fault Injection Handling library to mitigate physical attacks
Add Profile Large
Enable code sharing between boot loader and TF-M
Support Armv8.1-M Privileged Execute Never (PXN) attribute and Thread reentrancy disabled (TRD) feature
New platforms added
Add a TF-M security landing page
Enhance dual-cpu non-secure mailbox reference implementation

This is the first release performed in the OpenCI infrastructure with no single issue encountered.

Thanks to everyone who directly and indirectly contributed to this milestone.
