Xianghua Zhang · Jisuanji gongcheng · 2010
This paper proposes a digital image encryption algorihm which is based on the chaotic map network. A pseudorandom sequence is generated from a chaotic map network, which consists of four 1-D piecewise-linear maps. The pseudorandom sequence and the standard magic square are used for image encryption. The algorithm security is carried out with theory analysis and digital simulation. Experimental results show that the proposed encryption scheme has high security.
