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.
