摘要
基于口令的安全机制经常被应用到操作系统用户登录、个人电子账户、文档数据加密等各种信息系统中,用来保证账户的安全和用户信息的机密性。论文采用"字符摘取扩展变换"方法设计与实现了一种安全口令生成器,在保证用户方便记忆口令串的同时得到复杂高强度的口令串,从而提高了用户信息系统口令认证体制的密码安全。
The password-based security mechanism is often used to encrypt user log-on, personal e-account, document data and other information systems, and thus ,to protect e-account security and user information security. A secure password generator is designed and implemented through the method of ＂selection, extension and transform of characters＂ in this paper. It is guaranteed that the password is easy to be remembered while enough secure, thus enhancing the security of the information system password authentication scheme.
