摘要

PROBLEM TO BE SOLVED: To update a key version of a key value used for mutual authentication.

SOLUTION: A storage part 159 makes a first key value associated with first class information indicating a class of the first key value to hold the value and the information, and also makes a second key value different from the first key value associated with second class information indicating a class of the second key value to hold the value and the information. A detection responding part 211 sends predetermined first class information in response to a request for class information from a communication apparatus at the other end of communication. A mutual authentication part 213 performs mutual authentication with the communication apparatus using the first key value corresponding to the first class information if an authentication initiation command ordering an initiation of mutual authentication is sent back from the communication apparatus in response to the sent first class information, or performs the mutual authentication with the communication apparatus using the second key value corresponding to the second class information if the second class information is sent back from the communication apparatus in response to the first sent class information. The invention may be applied to an IC card or the like for the mutual authentication with an R/W.
