09031 Executive Summary – Symmetric Cryptography

Authors: Helena Handschuh, Stefan Lucks, Bart Preneel, and Phillip Rogaway

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

Abstract
Research in Symmetric Cryptography is quickly evolving. The seminar was the second of its kind, the first one took place in 2007. We observe a steadily increasing interest in Symmetric Cryptography, as well as a growing practical demand for symmetric algorithms and protocols. The seminar was very successful in discussing recent results and sharing new ideas. Furthermore, it inspired the participants to consider how Symmetric Cryptography has evolved in the past, and how they would like it to evolve in the future.

07021 Executive Summary – Symmetric Cryptography

Authors: Eli Biham, Helena Handschuh, Stefan Lucks, and Vincent Rijmen

Published in: Dagstuhl Seminar Proceedings, Volume 7021, Symmetric Cryptography (2007)

Abstract
The Seminar brought together about 35 researchers from industry and academia. Most of the participants came from different European countries, but quite a few also came from America and Asia. Almost all the participants gave a presentation. Most of them gave a "regular" talk of 30 to 50 minutes (including discussion time), some gave a "rump session" talk, and a few even gave two presentations, a regular one and another at the rump session.

A Collision-Resistant Rate-1 Double-Block-Length Hash Function

Authors: Stefan Lucks

Published in: Dagstuhl Seminar Proceedings, Volume 7021, Symmetric Cryptography (2007)

Abstract
This paper proposes a construction for collision resistant $2n$-bit hash functions, based on $n$-bit block ciphers with $2n$-bit keys. The construction is analysed in the ideal cipher model; for $n=128$ an adversary would need roughly $2^{122}$ units of time to find a collision. The construction employs ``combinatorial'' hashing as an underlying building block (like Universal Hashing for cryptographic message authentication by Wegman and Carter). The construction runs at rate~1, thus improving on a similar rate~1/2 approach by Hirose (FSE 2006).
