Abstract
Key information to be used for generating a decryption key is written into a storage area that can be referred to by an information processing apparatus via a predetermined wireless communication. If the elapsed time from when the key information is written into the storage area exceeds a predetermined time, control regarding the key information stored in the storage area is performed so as not to perform a registration process. In this case, the predetermined time differs according to an event when the key information is written.
