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

by Suresh.Marisetty＠infineon.com

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 Suresh Marisetty Infineon Semiconductor Corporation From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Anton Komlev via TF-M Sent: Friday, April 9, 2021 6:25 AM To: tf-m(a)lists.trustedfirmware.org Cc: nd <nd(a)arm.com> Subject: [TF-M] TF-M v1.3.0 release Caution: This e-mail originated outside Infineon Technologies.
