Hi ,

I can find AES DPA in TFM demo application, but  can't find TDES DPA implementation in TFM.

Please advise how to implement TDES DPA.

Hello @zqizh.1 ,

The AES DPA is based on a DPA resistant IP in STM32U5 SAES.

This IP does not support TDES for the reason mentioned by Peter.

Best regards

Jocelyn

Why would anyone invest time in implementing an encryption that is considered insecure and has long since been cracked?
