为实现解决微信息传输过程中身份认证和信息保密问题,提出了一种采用ECC算法实现的伪随机指纹公钥密码技术。首先对伪随机指纹公钥密码技术进行分析,然后给出伪随机数的产生过程和指纹特征值的随机变,设计出基于公钥密码机制的伪随机指纹密码系统,并采用ECC算法加以实现,最后给出实现该技术的主要代码,并在VC++6.0环境中验证通过。 In order to solve the problem of identity authentication and information confidentiality during the transmission of micro-information, a pseudo-random fingerprint public-key cryptography technology using ECC algorithm is proposed. First of all, we analyze the pseudo-random fingerprint public-key cryptography, and then give the pseudo-random number generation and the random change of the fingerprint eigenvalues. We design a pseudo-random fingerprint cryptography system based on the public key cryptosystem, Finally, the main code to achieve this technology is given and verified in VC ++ 6.0 environment.
