Abstract
A disclosed method for managing encryption keys, which may be performed by a key management server, responds to receiving, from a first client, a request to create a new key for a self-encrypting drive (SED) associated with the first client by retrieving unique identifiers of the first client and the SED, generating and storing the new key and a corresponding key identifier (KeyID), and associating the unique identifiers of the SED and first client with the new key. Upon receiving, from a second client, a locate key request that includes the SED identifier, providing the new key, the KeyID, and the first client identifier to the second client. Associating the SED and first client identifiers with the new key may include adding the identifiers as attributes of the KeyID. Embodiments may be implemented in accordance with a key management interoperability protocol (KMIP) standard.
