Sun Xiao-jun · Dianzi xuebao · 2004
This paper investigates a new image encryption method based on the stream cipher generated by a discrete Hopfield neural network.The experimental results show that the proposed discrete Hopfield neural network can be used to simulate complex nonlinear functions,and the period,0 and 1 equalization and sequence correlation properties of the output sequence can meet the requirements for the stream cipher design. Furthermore, the cipher can be easily implemented by digital circuits with parallel calculations to improve the processing speed.
