  • Patent number: 11777926
    Abstract: The embodiments described herein describe technologies to address initial establishment of device credentials in an Internet of Things (IoT) infrastructure. The embodiments are directed to unifying secure credential establishment regardless of the endpoint type, thus addressing the challenge of a great diversity among IoT devices. This approach is designed to address a challenge of initial trusted enrollment of the IoT endpoints into a secure infrastructure, which allows secure communications between the devices in the IoT environment.
    Type: Grant

  • Patent number: 11308196
    Abstract: Pairing data associated with a second device may be received at a first device. The pairing data may be received from a server. A first authentication proof may be generated based on the pairing data received from the server. A second authentication proof may be received from the second device. Furthermore, an authentication status of the second device may be updated based on a comparison of the first authentication proof that is based on the pairing data received from the server and the second authentication proof that is received from the second device.

  • Patent number: 10897363
    Abstract: A table key capable of decrypting a first table from a plurality of encrypted tables may be received. Each of the encrypted tables may include at least one pair of values corresponding to a challenge value and a response value. A request to authenticate a secondary device may be received and in response to the request to authenticate the secondary device, a challenge value obtained by using the table key to decrypt an entry in the first table may be transmitted to the secondary device. A second challenge value may be transmitted to the secondary device and a cryptographic proof may be received from the secondary device. The validity of the cryptographic proof received from the secondary device may be authenticated based on the second challenge value and the response value obtained by using the table key to decrypt the entry in the first table.
