基于令牌卡的多角色主机登录身份认证的设计与实现

Design and implementation of multi-role logon authentication based on tokencard system

身份验证是计算机安全的核心所在,是安全问题的第一道门户。探讨了令牌卡身份认证和及其扩展技术,并利用中间件的思想,提出了Windows操作系统的GINA扩展技术的改进方案,为增加双因素身份验证模块提供了较为灵活的机制。通过虚拟令牌技术,使用一块令牌实现了多角色主机登录认证,提高了系统管理的灵活性。

Authentication is the ＂core＂ and the first gateway to computer security system. With mentality ofmiddleware and the tokencard authentication system, the improved project of GINA and extensional technology on Windows are introduced and a more flexible mechanism for the two-factor authentication module is provided. With the virtual tokencard technology, the Tokencard make the multi-role logon authentication possible and it proves to be more flexible and reliable.
