I wanted to know if there is a way of sending arbitrary number of fixed plaintexts to ChipWhisperer-Lite or ChipWhisperer-Artix. From what I understand, that is done by manually changing the plaintext value in the “Fixed Plaintext” option given by the Capture software. Am I right? Is this the only way?
Thanks for the answers while I’m travelling, everyone
I think Adriel’s idea is the way to go. There’s a good example of sending very specific plaintexts in the TVLA test acquisition pattern. The point here is that you can write any plaintext/key generation code in newPair(). In this case, the TVLA test pattern is to randomly interleave “pseudo-random” plaintexts and a single fixed plaintext while keeping the same key.
