Patent attributes
A key management system includes a managed system coupled to a management system through a network. The managed system includes managed device locking subsystem(s) coupled to a managed device and a key storage. The managed device locking subsystem(s) retrieve, through the network from the management system, a managed device locking key that is configured to unlock the managed device. The managed device locking subsystem(s) then encrypt the managed device locking key to provide an encrypted managed device locking key, and store the encrypted managed device locking key in the key storage. Subsequent to storing the encrypted managed device locking key, the managed device locking subsystem(s) retrieve the encrypted managed device locking key from the key storage, and decrypt the encrypted managed device locking key to provide a decrypted managed device locking key. The managed device locking subsystem(s) then use the decrypted managed device locking key to unlock the managed device.
