Abstract: Due to universality and opening of the Internet,there're many hidden troubles of
information security in the network, so, identity authentication has becomed the necessary measure to ensure the security. This paper compared and analyzed the relative merits of common classes of
identity authentication, and on the basis of analysis, the authentication principle and its characteristics, and the authentication processing were also discussed, and after that, the identifying technology of USB Key with PKI system was designed from software and hardware detaily. All these design work and theory analysis is significative for enhance the security of the identifying authentication. Key words: Identity authentication; USB Key; PKI System; Technology design 1 引言
当前,随着计算机技术的飞速发展,利用因特网高科技手段进行经济商业犯罪的现象已经屡见不鲜了,因此,如何采用更加安全的数据保护及加密技术,成为当前计算机工作者的研究热点与重点。但是很多身份认证技术由于本身算法的漏洞而不稳定或可靠,使得很多不法之徒
