Abstract
A device is disclosed. The device may include a connection to a host or a management unit, a media to store a data, and a controller to access the data in the media based at least in part on a request from the host. A buffer may store a correctable event record, which may include fields. Some fields in the correctable event record may be encrypted using a homomorphic encryption (HE) algorithm and an encryption key.
Claims20
A device, comprising:
- a connection to a host or a management unit;
- a media to store a data;
- a controller to access the data in the media based at least in part on a request from the host;
- a buffer to store a correctable event record, the correctable event record including a first field and a second field, the first field encrypted using a homomorphic encryption (HE) algorithm and an encryption key;
- and
- an HE engine to encrypt the first field in the correctable event record using the HE algorithm,
- wherein the management unit is configured to predict an uncorrectable error at an address in the media based at least in part on the correctable event record, and
- wherein the encryption key is local to the device.
5 more elements
A method, comprising:
- detecting an event in a device;
- determining whether the event in the device includes a correctable event or an uncorrectable event;
- adding a correctable event record to a buffer of the device based at least in part on the event being a correctable event, the correctable event record including a first field and a second field;
- and
- encrypting the first field of the correctable event record using a homomorphic encryption (HE) algorithm and an encryption key,
- wherein the encryption key is local to the device.
3 more elements
A method, comprising:
- requesting, from a device at a management unit, a correctable event record, the correctable event record including a first field and a second field, the first field encrypted using an homomorphic encryption (HE) algorithm and an encryption key;
- receiving, from the device at the management unit, the correctable event record;
- applying, at the management unit, a prediction algorithm to the correctable event record to produce an encrypted address list;
- sending, from the management unit to the device, the encrypted address list;
- and
- receiving, from the device at the management unit, a decrypted address list,
- wherein the encryption key is local to the device.
