Abstract: Nowadays computer security becomes, increasingly, an indispensable field. It represents a major challenge for all entities: economic, political, social... However, few are the cryptographic systems that ensure security and still resists the enormous growth in technology. Now, cryptanalysis tools are much more sophisticated and more powerful than before. Hence, the need to design new systems that can be competitive to the old ones. New cryptographic systems with new properties and the ability to support this technology watch. In this work we have focused on the SEC encryption system uses a new approach of ciphering based on evolutionary algorithms, hence its called: symmetrical evolutionary ciphering. Since the strength of this type of algorithm will be very beneficial in cryptography, we will present in this paper, a new evaluation function that we have developed to improve the performance of this system and improve its resistance against all possible types of attacks.
