  • Generating a device identification key from a base key for authentication with a network
    Patent number: 11882102
    Abstract: A base key that is stored at a device may be received. A network identification may further be received. A device identification key may be generated based on a combination of the network identification and the base key. Furthermore, the device identification key may be used to authenticate the device with a network that corresponds to the network identification.
    Type: Grant

    Date of Patent: January 23, 2024
    Assignee: Cryptography Research, Inc.
    Inventors: Philippe Alain Martineau, Ambuj Kumar, William Craig Rawlings
  • Generating an authentication result by using a secure base key
    Patent number: 11539535
    Abstract: An encrypted sequence that includes an authentication key may be received. A base key stored at a device may be identified and the encrypted sequence may be decrypted with the base key to obtain the authentication key. A challenge value may be received and the authentication key may be combined with the challenge value to generate a device ephemeral key. An authentication result may be generated for the device based on a combination of the device ephemeral key and the challenge value. Furthermore, the authentication result may be transmitted to a mobile network to authenticate the device.
