Cryptanalysis Of Ciphertext Substitution Using Aco Algorithms

The document presents a first step towards the au-tomation of several techniques for classical crypta-nalysis of ciphertexts by substitution method without manual intervention using ACO algorithms. The tests presented are limited due to the large number of parameters used, including statistical tables of the literary languages of which belong to. The study focuses mainly on how to choose these parameters, a question that remains unanswered so far.
