Abstract
Systems and methods for using encryption keys to manage data retention are described. In one embodiment, the systems and methods may include receiving data such as user data from a host of the storage drive, encrypting the data using an encryption key, writing the encrypted data to the storage drive, and retaining the encrypted data on the storage drive based at least in part on a validity of the encryption key.
Claims20
A storage system comprising:
- a storage drive;
- and
- a controller to:
- encrypt data using an encryption key;
- store an encryption identifier in a first storage area of the storage drive;
- write the encrypted data to the storage drive;
- scan the first storage area for a link to an expired encryption key;
- determine the encryption key is expired based at least in part on the scan;
- and
- make storage space associated with the encrypted data available for storage of data different from the encrypted data after determining the encryption key is expired.

An apparatus comprising:
- a controller to:
- encrypt data using an encryption key;
- store an encryption identifier in a first storage area of a storage drive;
- write the encrypted data to the apparatus;
- scan the first storage area for a link to an expired encryption key;
- determine the encryption key is expired based at least in part on the scan;
- and
- make storage space associated with the encrypted data available for storage of data different from the encrypted data after determining the encryption key is expired.

A method comprising:
- receiving data from a host of a storage drive, the data including user data;
- encrypting the data using an encryption key;
- storing an encryption identifier in a first storage area of the storage drive;
- writing the encrypted data to the storage drive;
- scanning the first storage area for a link to an expired encryption key;
- determining the encryption key is expired based at least in part on the scanning;
