An efficient image encryption algorithm based on a novel chaotic map

In this paper, we propose a novel low dimensional chaotic map, namely, compounded piecewise linear map (CPLM) in order to balance between security and computational complexity. Then we prove the chaotic properties of CPLM theoretically and numerically. Based on the CPLM, an efficient chaotic image encryption algorithm is presented, in which the self-adaptive model and feedback mechanism are initially mingled to enhance the security. Besides,...
