Session Key Generation - CMAC - DESFire Light

Question asked by Wilmer Suarez on Nov 17, 2019

Hello,

 

I was wondering if there exists any demo code or library I can use for the session key generation during the DESFire Light & EV2 authentication sequence. Specifically, the CMAC calculation. I can successfully authenticate; but I've tried multiple solutions and I'm unable to calculate the correct session key.

 

Thank you
