A New Chaotic Sequence Encryption Algorithm

Chaotic system has fine cryptology characteristic property. The chaotic array has exceeding sensibility to initial condition and system parameter, as well as the chaotic array long range evolves bearing fruit be not allowed to forecast the sex characteristic property. Chaotic cryptology becomes a important research of modern cryptology forward position, and it have vastly developing a prospect.First this article introduces a few cryptology and chaotic cryptology knowledge, summarizes chaotic cryptology research current situation and chaotic mapping in common use. Know the degenerate problem of limited down chaotic accuracy condition system driving force characteristic and resolve way. Have summed up increasing the perturbation motion method; grouping some encrypt a scheme.In this article take summing up in at the head and Chaotic mapping of logistic and chaotic mapping of paragraph division linear as basis, bring forward one kind of new chaotic encryption algorithm. Have described the encryption algorithm concretely; have analysed the period encrypting the chaotic array; have proclaimed encrypted group; have testified the encrypted chaotic array having fine statistics characteristic property. Can moreover mention resist certain attack, Encryption algorithm have certain security.
