Summary

Research in Symmetric Cryptography is quickly evolving. The seminar was the third of its kind, the first one took place in 2007, the second in 2009. 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.

Two intense discussions dealt with Authenticated Encryption and the issue of a 'valid' attack on a symmetric primitive.

The participants agreed on Authenticated Encryption becoming a major research topic for Symmetric Cyptography in the next few years, because current Authenticated Encryption Schemes are not always suitable for practical demands -- escpecially are the relevant attack modes and models not yet well-understood (e.g., misuse attacks, blockwise adaptive attacks, etc.)

Regarding the issue of 'valid' attacks, the participants agreed that the current development of academic cryptanalysis with a growing number of increasingly 'marginal' attacks, is unsatisfactory.
