摘要
PROBLEM TO BE SOLVED: To provide a limited reception device which actualizes mutual authentication of high reliability even if a reception device main body and a security module do not hold a common global secret. SOLUTION: The reception device main body is equipped with a storage means which stores an ID for identifying a maker, a storage means which stores one or more pieces of information unique to the reception device main body, a deciphering means which deciphers information ciphered by using as a key the reception device main body unique information, and an authentication processing means which performs authentication processing with the security module by inputting the information outputted by the deciphering means. The security module is equipped with a storage means which stores a card ID for uniquely identifying the limited reception device, a means which filters reception device authentication information by referring to the maker ID and card ID, a storage means which stores one or more pieces of unique to the security module, and an authentication processing means which performs authentication processing with the reception device main body by inputting the security module unique information.
