METHOD AND DEVICE FOR MANAGING SECURITY KEY FOR COMMUNICATION AUTHENTICATION OF SUBSCRIBER STATION USED IN COOPERATIVE COMMUNICATION OF MULTIPLE BASE STATION IN RADIO COMMUNICATION SYSTEM

摘要

A subscriber station performs a method for managing a security key. The method includes generating, for each of the base stations, an input value for generation of the security key for data transmission and reception with the each base station; transmitting, to the each base station, the input value for a corresponding base station; and generating the security key of the corresponding base station by using the input value of the each base station. A base station provides cooperative communication to the subscriber station.
