CEC 2003 Special session at the Congress on Evolutionary Computation, Canberra, Australia, December 8-12, 2003 There is a growing interest from the computer security community toward Evolutionary Computation techniques, as a result of these recent successes, but there still are a number of open problems in the field that should be addressed. This special session will try to do it by asking for submissions in all areas of evolutionary computation dealing with applications to computer security, and by giving the interested researchers an opportunity to review the current state-of-art of the topic, exchange recent ideas, and explore promising new directions. We would like to invite your participation in the special session Evolutionary Computation in Computer Security at the CEC-2003, an opportunity to meet leading researchers in the field, exchange ideas and initiate collaborations. Relevant topics include, but are not limited to Cellular automata, Genetic Algorithms, Genetic Programming, Classifier Systems, Simulated Annealing, Evolutionary Strategies, Tabu Search, Bio-inspired systems, etc. in: - Design of cryptographic primitives, including: pseudo-random number generators, block ciphers, stream ciphers, hash functions, S-Boxes, etc... - Analysis and/or cryptoanalysis of cryptographic primitives - Cryptography - Improvement of cryptographic primitives - Network security - Intrusion detection systems - Host security More information can be found at http://tracer.uc3m.es/CFP-SS-CEC2003.html/
