An online chaotic image secure communication system with the encryption/decryption method of grey value substituting and position shuffling is designed and implemented for the network, which is realtime and secure for communications. By the use of the Lorenz and Logistic chaotic systems, with a key synchronization scheme, the original image information can be encrypted in a realtime way and the cipher information is transmitted via TCP. With the properties of randomness and its sensitivity on the initial conditions, the encrypted transmitting messages are secure and difficult to be eavesdropped. The implementation method of the system is studied, and the communication results show its security and practicability.
