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.

Note: Corrected chosen-plaintext attack memory requirement notation.
