Image Encryption Method Based on Two-Dimensional Piecewise Linear Maps
-
Abstract
Put forward two-dimensinal piecewise linear maps, demonstrate the maps are chaotic.Use the maps to get the random matrixs and random sequences which are needed to encrypt images, reach the destination of encrypt processing by using xor operation and circular shifting operation.The method is simple and practical, experimental show that the effect of encrypted image is good and has higher security.
