摘要
身份认证技术是信息安全中的基本技术以及重要内容,在信息系统中,它是第一道防线,起到了鉴别用户身份的关键作用。在涉密网络、军工单位等关键领域内,随着信息化建设的加速发展,研究适用不同场景、不同网络环境下的身份认证技术具有重要意义和广阔的应用前景。本文将介绍身份认证技术的分类、发展及运作原理,并就静态密码、动态密码、硬件数字证书载体及生物特征识别四种主流身份认证技术的技术要点、关键问题以及在关键领域中的适用性情况进行分析对比。
Identity authentication technology is the basic technology and the important content of information security, in the information system, it is the f irst line of defense, plays a key role in the identif ication of user identity. In the classified network, military units, and other key areas, with the accelerated development of information construction of study for identity authentication technology under different scenarios, different network environment has important significance and broad application prospects. The identity authentication technology classification, development and operation principle, and static password, dynamic password, hardware digital certifi cate carriers and biological characteristics to identify four kinds of the mainstream technology of identity authentication techniques, key problems and in key areas of applicability conditions for comparative analysis are introduced in this paper.
