Di Xiao, Xiaofeng Liao, Kwok‐Wo Wong · IEEE Transactions on Circuits and Systems II Analog and Digital Signal Processing · 2006
In this brief, we analyze the cause of vulnerability of the original dynamic look-up table based chaotic encryption scheme in detail, and then propose the corresponding enhancement measures. Theoretical analysis and computer simulation indicate that the modified scheme is more secure than the original one
