SYSTEM AND METHOD FOR PREVENTING REPLAY ATTACKS IN WIRELESS COMMUNICATION

摘要

A method and apparatus for confirming the identity of a mobile station in a communication network. A mobile station transmits a security value to obtain access to the network. The system authenticates the mobile station prior to granting it access to the network. The system performs an additional procedure before granting access to the system if the security value sent by the mobile station matches a previously transmitted security value. Using this invention, the system prevents attempts of replay attacks by intruders.
