FORMATION OF ENCODED KEY AND RENEWAL METHOD OFFERING MULTICAST BROADCAST SERVICE IN WHICH EFFICIENT DATA COMMUNICATIONS, SECURITY AND RELIABILITY ARE GUARANTEED

摘要

PURPOSE: By using common information of the base station and terminal it is efficient and the formation of encoded key and renewal method are steadily distributed the encryption key for MBS.;CONSTITUTION: A terminal(MS) requests the MBS(Multicast Broadcast Service) traffic key information by transmitting the PKMv2 key request message with a serving base station(SBS)(S301). The serving base station transmits the PKMv2 key reply message including the traffic key information in the terminal(S303). The terminal is created GTEK by using the GTEK nonce included in the PKM key reply message, and the GTEK counter and MAK field(S305).;COPYRIGHT KIPO 2010
