Attacking AES first round on CW305

[AAA]

Thanks for your reply Alex.

I was referring to this post:

Side Channel Analysis/Power Analysis Attack in SAKURA X

Hello, You’ll have to concentrate based on your desired model - for example if your hypothetical value is based on the leakage of the first S-Box operation that would be the one to concentrate on. But using a Hamming Distance (HD) model would be more suitable. I haven’t used the SAKURA X myself so don’t know details of how many traces it would take. What speed is the AES core running at?
