An apparatus includes an interface module, a controller, a key storage module, where the key storage module is configured to store a key, and a non-volatile storage module that is configured to store data. The non-volatile storage module has a first partition and a second partition, where the first partition is designated as a read-only storage area for the data and the second partition is designated as a write-only storage area for new data. The first partition is re-designated as the write-only storage area for other new data and the second partition is re-designated as the read-only storage area for the new data in response to the new data being written to the second partition with a signature and the controller verifying the signature using the key stored in the key storage module. |
