摘要： PURPOSE: A group key management method and an apparatus thereof are provided to obtain a group key in a base station about an updated group key by transmitting a group key from the other mobile device. CONSTITUTION: A verification message is transmitted(601,601-1). Each verification message is received(602,602-1). Each session key is generated(605). The session key is manufactured in order to encode a group key. A transmitter encodes the group key to the session key. The transmitter transmits the encoded key with a group key version. A receiver receives the encoded group key.
