%X Study a new formula for amplitude discrete chaotic sequence to encrypt images under hardware devices conveniently from Logistic mapping formula for continuous amplitude, and generate a longer period sequences by exclusive OR algorithm with three amplitude discrete digital chaotic sequence in different periods, The image is encrypted by exclusive OR algorithm with the longer period image encrypting sequence and original image. The method is sensitive to initial values through simulation of encrypting and decrypting image. The result shows that the manner to generate amplitude discrete chaotic sequence is simple and more secure for information security, more convenient for hardware to encrypt images.
