- The present invention relates to a method for allocating an authorization key identifier in a wireless portable Internet system. In a privacy key management version 2 (PKMv2) of the wireless portable Internet system, a base station generates PAK identifier, PMK identifier, and authorization key identifier for distinguishing a primary authorization key (PAK) shared by the base station and the subscriber station in an RSA-based authorization, a pairwise master key (PMK) shared by the base station and the subscriber station in an EAP-based authorization, and authorization keys generated by the PAK and the PMK. The base station transmits PAK identifier, PMK identifier, and authorization key identifier to the subscriber station and shares them with the subscriber station. Therefore, the base station and the subscriber station may easily distinguish more than 2 authorization-related keys. In addition, it is possible to transmit the signal message efficiently in the radio channel by reducing the sizes of the PAK identifier, PMK identifier, and authorization key identifier.
