    Abstract: 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.

    Abstract: The present invention relates to encryption and decryption apparatuses in a wireless portable Internet system, and a method thereof. In the wireless portable Internet system, a subscriber station and a base station share an encryption during key distribution, and a message is encrypted with the encryption key and transmitted. In this case, a first initial vector is generated for encryption based on information shared by the subscriber station and the base station in a wireless channel, and the message is encrypted with the first initial vector and the encryption key and is then transmitted. In addition, a second initial vector for decryption is generated based on information shared by the subscriber station and the base station in the wireless channel, and the encrypted message is decrypted with the second initial vector and the encryption key. Herein, the first initial vector corresponds to the second initial vector.

    Abstract: In a retransmitting method, at least one ARQ block included in a first PDU is fragmented into a plurality of ARQ sub-blocks, and at least one second PDU is generated from the plurality of ARQ sub-blocks. The second PDU includes a payload including an extended header and at least some of a plurality of ARQ sub-blocks. The extended header includes a field representing a sequence number of the first ARQ sub-block belonging to the payload.

    Abstract: A method of controlling retransmission in a transmitter, the method provides transmitting a medium access control (MAC) management message to a receiver by hybrid automatic retransmit request (HARQ) and initiating retransmission of the MAC management message when an HARQ process is terminated with an unsuccessful transmission of the MAC management message before an expiration of a retransmission timer for the MAC management message.
