<p>A method for transmitting and receiving data of a terminal in a communication system and a communication terminal thereof are provided, which can minimize an exposure of authentication information. A communication terminal includes a rolling token generation unit for generating the rolling tokens; a memory for storing the generated rolling tokens; and a control unit for, if an authentication of the other terminal for performing a communication is completed, generating and transmitting a rolling token whenever a transmission to the other terminal is performed, and in case of receiving a specified rolling token from the other terminal, determining whether the rolling token currently received from the other terminal is identical to the rolling token most recently transmitted.</p> |
