Abstract

An encryption key management system is provided for storage area network devices. A create key request is received at a storage area network switch. The key is created at the storage area network switch and the created key request is transmitted to a key management center. The key object is stored in the key management center and includes a unique identifier, an encrypted key, a wrapper unique identifier, and a key entity. The encrypted key can later be decrypted to generate a decrypted key. The encrypted key is decrypted using keying material accessed using the wrapper unique identifier that identifies another key object.
