%! Attack on the Simple Substitution Ciphers Using Particle Swarm Optimization
%R 10.30684/etj.28.11.6
%X This paper considers a new approach to cryptanalysis based onsimulation of behavior of flocks of birds and schools of fish called ParticleSwarm Optimization (PSO). It is shown that such algorithm could be usedto break the key for a simple substitution cipher. This paper presents aproposed 2-opt PSO algorithm to enhance the efficiency of PSO algorithmon attacking simple substitution ciphers.
