1. An authentication system that performs authentication through wireless communication between a portable terminal and a communication peer and permits actuation of the communication peer based on an authentication result, the authentication system comprising:
a first input and a second input arranged at separate positions and allowing for input of authentication information used for the authentication;
a first calculation circuit that utilizes a first calculation equation to calculate a first calculation result and wherein the first calculation equation uses both the authentication information input to the first input and a communication peer authentication parameter registered to the communication peer;
a second calculation circuit that utilizes a second calculation equation to calculate a second calculation result and wherein the second calculation equation uses both the authentication information input to the second input and a portable terminal authentication parameter registered to the portable terminal; and
an authentication circuit that performs the authentication by comparing the first calculation result and the portable terminal authentication parameter resulting from the authentication information being input to the first input and performs the authentication by comparing the second calculation result of the second calculation circuit and the communication peer authentication parameter resulting from the authentication information being input to the second input.
