摘要：In this paper, we present a new symmetrical encryption system based on the binary extension of the symmetric encryption system SEC, which transforms the encryption issue into a combinatorial optimization problem using basic tools such as evolutionary algorithms. Our main objective is to change the appearance frequencies of plaintext binary blocks, to make statistical cryptanalysis impossible. We designed a new encryption method called �Binary fusion Process (BFP)�, it is a preparatory step for the application of evolutionary algorithm, and can in fact generate a more interesting initial population. Through the key generated by our algorithm, we illustrate the process of encryption and decryption, and then we present our various applications while interpreting them. Finally, to evaluate our system we compare it to other well known systems. Moreover, the experimented results show that the robustness of our system is undeniable to any attack by frequency analysis.
