Abstract
This paper presents a self-adaptive image encryption algorithm based on hyper-chaotic system.Firstly, the hyper-cha-otic sequences which are pretreated are transformed according to the plaintext pixel information that result in both key sensitivity and plaintext sensitivity;then, the last encrypted pixel is used to produce intermediate key through nonlinear operation to encrypt the next pixel adaptively , until all pixels are encrypted completely;finally, the simulation analyses are performed using statistical property , anti-differential attacks , key sensitivity and key space and algorithm efficiency .Experimental results show that the algo-rithm is secure and efficient .关键词
