Abstract:
A confidential information setting apparatus includes: a communication unit that acquires an encryption key and condition information, which is a condition for setting a secret key to a terminal, from a memory unit of a server and acquires a terminal ID, which is an identifier for uniquely identifying the terminal, and the secret key associated with the terminal ID and encrypted from a memory unit of a user apparatus; an encryption processing unit that decrypts the encrypted secret key with the encryption key; and a control unit that judges whether the decrypted secret key can be set to the terminal or not, based on the condition information and sets the secret key to the terminal when a result of the judgment indicates that the secret key can be set to the terminal.
