Abstract: The digital image encryption algorithm of a chaotic neural network is proposed. According to a binary sequence generated from a chaotic system, the weights and biases of the network are set for the encryption and or decryption of each signal element. The features of the algorithm are computational complexity, no distortion and high security. Examinations have shown that preliminary results are satisfactory.
