The Study Of Signals' Encryption Based On Lorenz Chaos System And Liu Chaos System

With the consistently increasing development of the chaos encryption communications' study, traditional data encryption techniques is not able to meet the demand caused by the network security , it is very necessary to study new encryption systems and methods . Based on the summary to a lot of literature in our and foreign countries, this paper identifies the encrypted effect and the ability of resisting noise on Lorenz chaos system and Liu chaos system via additive masking mode , functional encoding and decoding mode , and driving functional switch-modulated method , simulation result of the numerical value shows that driving functional switch-modulated method holds high security and effectively resisting noise . These analyses and results give reference to the applications of synchronization chaos on encryption communications.
