Abstract
A storage device includes: a control unit configured to determine, when a first command to update first data stored at a first address in a first area of a storage unit to second data is received from an external apparatus, whether or not an update from the first data to the second data is within an update restricted range. In a case where the update to the second data is not within the update restricted range, the control unit is configured to verify a signature received from the external apparatus together with the first command. In a case where a verification is success, the control unit is configured to store the second data at the first address. In a case where a verification is failure, the control unit is configured not to store the second data at the first address.
