The workshop concentrated on all aspects of fast primitives for symmetric cryptology, including the design, cryptanalysis and implementation of block and stream ciphers as well as hash functions and message authentication codes. The first FSE workshop was held in Cambridge in 1993, followed by Leuven in 19
