無線網路之安全快速的OTP身份認證協定

Abstract

Wireless Networks provide more flexibility and connectivity to the users, to be connected with anyone, any time, any where. This feature makes the wireless networks to be wide open to threats and attacks by the intruders. To ensure a reliable and secure wireless environment, suitable authentication protocols have to be employed based on the network infrastructure. The scope of this thesis is to present a general approach of design and analysis, of an authentication protocol, which is robust and easy to implement in real time. Along with these aspects, this protocol is coupled with secure and fast authentication features and especially designed for large scale enterprise wireless networks. The protocol design is formalized with Protected One Time Password Server (POTP), which ensures secure One Time Password (OTP) authentication and an RADIUS Authentication, Authorization and Accounting (AAA) server which favors the user authentication. The Access Point (AP) involves in the subsequent authentication phase for the user requests.
