Digital image encryption algorithm based on Chaos system
Jun Luo · Jisuanji gongcheng yu sheji · 2009
A new digital image encryption is proposed.Firstly,the real sequences generated from Lorenz chaotic system are pretreated and a pseudorandom integer sequences is gotten and used as the key streams.Then,the nonlinear transformation and the standard magic square transformation are used for image encryption.Thorough experimental tests are carried out with detailed theory analysis,demon-strating the high security and strongly against attacks of the new scheme.
