ABSTRACT:
In a communication system having a first communication device and a second communication device for carrying out communications by setting up a communication link, the identification code generated at one of the first and second communication devices is presented to the other, and the authentication data are generated by using this identification code at the both of the communication devices, so that the illegal acquisition of the identification code can be prevented and the security performance can be improved.
