  • Patent number: 10148669
    Abstract: An encryption key management system includes an encryption IHS that is coupled to a network. The encryption key management system also includes a host processing system. An off-host processing system in the encryption key management system is coupled to the host processing system and is coupled to the encryption IHS through the network. The off-host processing system provides an encryption key request to the encryption IHS through the network, receives an encryption key from the encryption IHS through the network and stores the encryption key, provides the encryption key to the host processing system in response to authenticating a user, and revokes the encryption key in response to a revocation instruction received from the encryption IHS through the network. The providing the request, and the receiving, providing, and revoking the encryption key may be performed by the off-host processing system while the host-processing system is not in an operating mode.

  • Patent number: 9667602
    Abstract: An off-host authentication system includes an authentication information handling system (IHS) that is coupled to a network. The off-host authentication system also includes a host processing system. An off-host processing system in the off-host authentication system is coupled to the host processing system and is coupled to the authentication IHS through the network. The off-host processing system provides an encrypted primary authentication item to the authentication IHS through the network. The off-host processing system then receives an encrypted secondary authentication token from the authentication IHS through the network. The off-host processing system then decrypts the encrypted secondary authentication token to produce a decrypted secondary authentication token and uses the decrypted secondary authentication token to retrieve a tertiary authentication token.

  • Patent number: 9577994
    Abstract: An off-host authentication system includes a network. An off-host processing system is coupled to the network and sends an encrypted authentication item through the network in response to validating a user. An authentication information handling system (IHS) is coupled to the network and receives the encrypted authentication item from the off-host processing system through the network, decrypts the encrypted authentication item to produce a decrypted authentication item, validates the decrypted authentication item, and sends an approval message through the network. A directory system is coupled to the network and receives the approval message through the network and, in response, sends a user approval through the network. A host processing system, which is located in a user IHS that includes the off-host processing system and which is coupled to the network, logs a user into the user IHS in response to receiving the user approval through the network.

  • Publication number: 20090251406
    Abstract: An information handling system has a chassis and a lid, the lid rotating between a closed position and a tablet position. An indicator coupled to the lid, such as a magnet, aligns with a first detector coupled to a chassis of the information handling system, such as a Hall effect detector, in the tablet position so that the detector signals to a position detector module to disable a keyboard of the information handling system. The indicator aligns with a second detector coupled to the chassis in a closed configuration so that the second detector signals to the position detector module to enter a power down state.
