A real-time video secure communication scheme based on Logistic chaotic sequence is presented in this paper,which has been accomplished on the platform of SEED-VPM642.This scheme focuses on the principle of parameter-changeable,fixed-point operation and chaotic dynamic encryption algorithm,and improves the traditional encryption algorithm.In order to realize information security and confidentiality,a Logistic discrete chaotic system is embedded into video transmission system for video encryption,the security and performance of the proposed algorithm is also estimated.The result shows that: compared with Lorenz system,this algorithm possesses favorable characters of real-time and speediness,which can guarantee fluency and security of network video communication system.
