【Abstract】 The PKI technology has been widely used in information security domain. Its applica-tion in Linux system is far-reaching. This paper analyzes the authentication theory based onusername and password and the security trouble in Linux system. A new authentication mode foruser based on PKI and challenge/response is produced. It can prevent replay attack and dictio-nary attack. It produces a good example for further security study in Linux operating system.更多还原
