| Abstract: | In order to improve security of encryption algorithm based on cat map chaotic system, an extended cat map chaotic system was proposed based on two-dimension cat map chaotic system and extended addition operation, and the sequence generated by this method was pseudorandom, The correlation performance and balance performance of the extended two-dimension chaotic sequence were analyzed. Simulation results show that the extended chaotic sequence generated by using our method is pseudorandom and its correlation performance and balance performance are good. |
