摘要
指出公钥密码数字签名无法阻止拷贝攻击这一缺陷产生的原因。通过将信息载体纸张中纤维混沌图像与RSA公钥算法相结合,给出一种可抵御对明文和数字签名拷贝攻击的数字签名方法。通过将Lorenz混沌算法与RSA公钥算法相结合,改进私钥计算方法,设计出一种可以控制私钥数字的混沌公钥密码算法。
Points out the causes of that the RSA public key cryptography digital signature can not stop the copy attack. By the combination of the chaotic image of paper fiber in the information carrier and RSA algorithm, gives a kind of digital signature method against the copy at- tacking for plaintext and the digital signature. By the combination of Lorenz chaos algorithm and RSA algorithms, improves the private key algorithm and sets the private key in the Chaos public key algorithm of randomly.
