| Abstract: | Chaotic system has complex dynamic behavior.A complex system of 8-scroll chaotic system was applied in which its chaotic characteristic was used.Based on the driven response synchronization,signals were added into and a closed loop and feedback in order to make drive system and response system achieve synchronization and to realize the encryption and decryption for Lena image.Finally,Matlab simulation software was used to compile corresponding encryption and decryption process and show out simulation figure. |
