In this paper, the proposed technique use high speed stream cipher approach because this approach is useful where less memory and maximum speed is required for encryption process. In this proposed approach Self Acclimatize Genetic Algorithm based approach is exploits to generate the key stream for encrypt / decrypt the plaintext with the help of key stream. A widely practiced approach to identify a good set of parameters for a problem is through experimentation. For these reasons, proposed enhanced Self Acclimatize Genetic Algorithm (GAKG) offering the most appropriate exploration and exploitation behavior.Parametric tests are done and results are compared with some existing classical techniques, which shows comparable results for the proposed system.
