Hi Suresh,

TF-M threat model against physical attack requires Cryptographic operations to be protected as well.

Since the sensitive operations are performed in crypto library or HW accelerator, it is required the corresponding crypto SW and HW shall implement counter measures.

Regrading Mbed TLS mitigation, please refer to Mbed TLS mailing list for details.

Best regards,

Hu Ziji

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

• 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.
