Zusammenfassung:	A method and system for authenticating in a communication system are provided. The method includes, in a first authenticator, sending an authenticator relocation request to a second authenticator transmitting a hash value for an authentication parameter of a Mobile Terminal (MT), a random parameter 1, and a random parameter 2 from the second authenticator to the first authenticator; in the first authenticator, transmitting the hash value received from the second authenticator and the random parameter 1 to an Authentication, Authorization, and Accounting (AAA) server; in the AAA server, determining a validity of the hash value received from the first authenticator, and in the AAA server, transmitting the authentication parameter ever used at the time of authenticating the MT, to the first authenticator.
