Abstract
Systems and methods for hash authenticated data are described. In one embodiment, the storage device includes a storage drive and/or a controller. In some embodiments, the controller is configured to identify data to be authenticated, compute a first hash of the data using a hash function, detect a trigger event associated with the storage drive, and authenticate, after the trigger event, the data based at least in part on the first hash of the data.
Claims20
A storage system comprising:
- a storage drive;
- and
- a controller to:
- identify data to be authenticated;
- compute a first hash of the data using a hash function;
- detect a trigger event associated with the storage drive;
- and
- authenticate, after the trigger event, the data based at least in part on the first hash of the data.

An apparatus comprising:
- a controller to:
- identify data to be authenticated;
- compute a first hash of the data using a hash function;
- detect a trigger event associated with the apparatus;
- and
- authenticate, after the trigger event, the data based at least in part on the first hash of the data.

A method comprising:
- identifying data to be authenticated;
- generating a first hash of the data using a hash function;
- detecting a trigger event associated with the storage drive;
- computing, after the trigger event, a second hash of the data using the hash function;
- and
