Cryptanalysis of block EnRUPT

Elias Yarrkov

Abstract: EnRUPT is a cryptographic primitive with a variable block and key length. We show several attacks on it that stem from properties of its keying, including a very fast related-key attack.

Category / Keywords: secret-key cryptography / cryptanalysis, related-key attack
