摘要
该文针对一种超混沌图像加密算法进行选择明文攻击,结果表明该算法中间密钥序列与明文图像不存在关联,所采用的加密公式可进行反推运算,并且待加密像素仅仅采用异或的加密方式,导致中间密钥序列可被破解,进而可对密文信息进行恢复。
Chosenplaintext attack is introduced in this paper. The target ofthe attack is an image encryption algorithm based on a hyper-chaotic system. Results show that the intermediate key sequence of this algorithm has nothing to do with the plaintext with its encryption formula can be of anti-push operation, and the encryption ofpixel which to be encrypted only adopt the method of XOR. These make the intermediate key sequence be decoded, so as to all the cipher-text.
