Abstract
Systems and methods for encryption key shredding to protect non-persistent data are described. In one embodiment, the storage system device may include a storage drive and a controller. In some embodiments, the controller may be configured to power on the storage drive, identify an encryption key on the storage drive created upon powering on the storage drive, and encrypt data in a cache of the storage drive using the encryption key. In some embodiments, the controller may be configured to power off the storage drive and delete the encryption key upon powering off the storage drive. In some cases, the storage drive may include at least one of a solid state drive and a hard disk drive. In some embodiments, the storage drive may include a hybrid storage drive that includes both a solid state drive and a hard disk drive.
