I have been reading the Simon Cipher paper. It has the line: "The SIMON key schedules employ a sequence of 1-bit round constants specifically for the purpose of eliminating slide properties and circular shift symmetries", and I am curious.
I have read on the theoretical attack, but I am trying to find an approach to learn about the actual attack. I hope to break the Simon key schedule to make it susceptible to a slide attack and the SIMON32/64 bit-width is small so it might be possible. If I remove the constant z0 that is added to protect from a slide attack, I should be able to succeed in the attack.
Is there a good primer for slide attacks?
