    Abstract: Provided are an apparatus and a method for anonymity-based authentication and key agreement which are capable of providing transmission message binding properties, which ensure that the messages received via a plurality of rounds by participants who desire key agreement as well as anonymity have been sent by the same counterpart participants. The provided apparatus comprises: a signature verification unit which receives a plurality of messages, each carrying a signature generated based on link information of a sender, and verifies the signature of each of the messages; and a binding checking unit which determines whether the messages have been sent by an identical sender, if it is determined by the signature verification unit that the signature is valid, based on the link information of the signature.

    Abstract: The method is for the key distribution method for the user of communication system. The method comprises the first step which calculates the secret common key (M) between terminal (2) and terminal (3) using the open key of the correspondence (Yi,Yj) and his secret key (Si,Sj); the second step which transfers the random number (Rj) into terminal (i(2)) after generating the random number (Ri); and the third step which calculates the session key (Ks) using the terminal (i(2)), terminal (j(3)) and the random number (Ri,Rj).

    Abstract translation: 该方法用于通信系统用户的密钥分发方法。 该方法包括使用对应关系（Yi，Yj）的开放密钥和他的秘密密钥（Si，Sj）计算终端（2）和终端（3）之间的秘密公共密钥（M）的第一步骤。 在产生随机数（Ri）之后将随机数（Rj）传送到终端（i（2））的第二步骤; 以及使用终端（i（2）），终端（j（3））和随机数（Ri，Rj）计算会话密钥（Ks）的第三步骤。
