Practical Collisions for EnRUPT

Authors: Sebastiaan Indesteege and Bart Preneel

Published in: Dagstuhl Seminar Proceedings, Volume 9031, Symmetric Cryptography (2009)

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.

Practical Preimages for Maraca

Authors: Sebastiaan Indesteege and Bart Preneel

Published in: Dagstuhl Seminar Proceedings, Volume 9031, Symmetric Cryptography (2009)

Abstract
We show a practical preimage attack on the cryptographic hash function Maraca, which was submitted as a candidate to the NIST SHA-3 competition. Our attack has been verified experimentially.

The Lane hash function

Authors: Sebastiaan Indesteege, Elena Andreeva, Christophe De Cannière, Orr Dunkelman, Emilia Käsper, Svetla Nikova, Bart Preneel, and Elmar Tischhauser

Published in: Dagstuhl Seminar Proceedings, Volume 9031, Symmetric Cryptography (2009)

Abstract
We propose the cryptographic hash function Lane as a candidate for the SHA-3 competition organised by NIST. Lane is an iterated hash function supporting multiple digest sizes. Components of the AES block cipher are reused as building blocks. Lane aims to be secure, easy to understand, elegant and flexible in implementation.
