Abstract :
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
