摘要
Abstract
Current image encryption algorithms are not resistant to plaintext-chosen attack. In order to solve the question, a new image encryption algorithm based on adaptive parameters is proposed. The improved image barycentric coordinates are chosen as adaptive parameters. The adaptive parameters and user keys are input into four-dimensional hyperchaotic system to generate chaotic sequences to encrypt image. And the adaptive parameters are saved into encrypted image by reversible watermarking technology. Experimental results show that the algorithm is expediently to manage keys and can resist some attacks such as chosen-plaintext attack.关键词
