An implementation of a Sim based strong authentication system using one time passwords and Active Directory.
暫譯: 基於一次性密碼和Active Directory的Sim模擬強身份驗證系統實作

This dissertation addresses the security issues of the current password systems identifying their weaknesses and reporting on a system that uses a Subscriber Identity Module (Sim) card as an authentication device. The need for stronger identification devices is justified with references to related literature and experience analysing password usage and password security systems employed in various organisations. A new password system is developed describing its design, stages of its implementation, methods of testing and possible future enhancements.
