摘　　要：利用混沌序列相位掩模对图象在联合变换相关器中进行加解密,方法具有很强的抗盲解密的能力,而且相位掩模可以重构,便于密钥的保存与传输。计算机模拟的结果表明了方法的可行性。The phase mask plate with chaotic sequence is used to encode image in the joint transform correlator so as to encrypt the original image.The characteristic of this method has high security,and moreover,the secure key can be regenerated.It makes the practical use convenient.The results of computer simulation show the feasibility of this method.
