Electronic apparatus and control method of electronic apparatus

An electronic device includes a first device, a second device, and a storage area shared by the first device and the second device when performing mailbox communication between the first device and the second device. When transmitting first data from the first device to the second device via the mailbox communication, the first device stores first data in the storage area. The second device, which has stored therein an identifier of a device permitted to transmit data to the second device via the mailbox communication, obtains an identifier of the first device, and compares the obtained identifier to the identifier stored in the second device to determine whether acquisition of the first data from the storage area is permitted. When the acquisition of the first data from the storage area is determined to be permitted, the second device reads the first data from the storage area.

A system software unit performs a first authentication operation with an external device using a first key that is registered in advance. A secure software unit determines whether or not system software satisfies a soundness condition. A dedicated memory unit is used to store a second key. While performing a reregistration operation for reregistering the first key, a system software unit requests the secure software unit to read the second key. When the system software satisfies the soundness condition, the secure software unit generates verification data using the second key. When a second authentication operation performed with the external device using the verification data is successful, the system software unit performs the reregistration operation.
