Practical Collisions for EnRUPT

Abstract

The EnRUPT hash functions were proposed by O'Neil, Nohl and Henzen as candidates for the SHA-3 competition, organised by NIST. The proposal contains seven hash functions, each having a different digest length. We present a practical collision attack on all of these seven EnRUPT variants.
The time complexity of our attack varies from $2^{36}$ to $2^{40}$ round computations, depending on the EnRUPT variant, and the memory requirements are negligible. We demonstrate that our attack is practical by giving an actual collision example for EnRUPT-256.
