  • Patent number: 11838408
    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.

  • Patent number: 11740806
    Abstract: An information handling system may include a processor and a management controller communicatively coupled to the processor. The management controller may be configured to, in response to an encrypted storage resource being coupled to the information handling system: transmitting a request to at least one other management controller for an encryption key associated with the encrypted storage resource; receiving a response from the at least one other management controller, the response including the encryption key associated with the encrypted storage resource; and unlocking the encrypted storage resource with the received encryption key.

  • Publication number: 20220350930
    Abstract: An information handling system may include a processor; an encrypted storage resource, wherein the encrypted storage resource is coupled to the information handling system via a storage controller that does not implement locking and unlocking functionality for the encrypted storage resource; and a management controller configured to: receive a request to unlock the encrypted storage resource; determine an encryption key associated with the encrypted storage resource; and unlock the encrypted storage resource with the received encryption key via a sideband interface coupling the management controller to the encrypted storage resource.

  • Publication number: 20100066017
    Abstract: A portable activity device for playing entertaining and educational games and activities. The activities may also be adapted for provision of physical therapy and occupational therapy. The device features a case having an accessible cavity for storage of activity components. A side surface of the case is magnetically receptive to the activity components which have magnets upon them. The device maintains the activity pieces in place in moving vehicles allowing children to play games during travel without the risk of sharp movements causing the game parts to fall. A white board on the exterior surface is provided which may be employed with markers stored in the cavity.
