In this paper a new algorithm for designing encryption systems based on Coupled Map Lattices (CML) hyperchaotic map is introduced. The algorithm is based on the two outputs of the hyperchaotic map, using one of the output's even bits and the other’s odd bits to consist the new sequences which can be utilized as stream ciphers. The characteristic of the sequence has been analyzed which hurdles the shortcoming of mutual restriction between the successive values of the original hyperchaotic sequence, and the structure of the cryptosystem is presented, which shows that the software implementation of the scheme is easy. Finally, this paper presents analysis on the speed and security analysis.
