PROBLEM TO BE SOLVED: To make it difficult to analyze an authentication code of pairing in an electric lock device.SOLUTION: An electric lock device for transmitting/receiving signals between paired apparatuses while collating authentication codes uses two kinds of authentication codes A and B. The code B is used for signals with high importance of security for unlocking or the like. The code A is used for signals with low importance of security other than unlocking. Thus, the authentication code B is transmitted only when performing locking. Consequently, it is made difficult to steal the authentication code and it can be made difficult to analyze the authentication code. |
