Patent number: 11871225Abstract: A first wireless access device, associated with a wireless service provider, establishes a wireless local area network connection with a second wireless access device and receives a certificate including a unique identifier associated with the second wireless access device. The first wireless access device determines whether the second wireless access device is authorized to connect to the first wireless access device. For example, if the certificate is signed by a certificate authority associated with the wireless service provider and the unique identifier appears in a whitelist stored at the first wireless access device, the first wireless access device and the second wireless access device perform a mutual authentication procedure based on one or more ephemeral keys. The first wireless access device provides the second wireless access device with access to a wide area network based on successful completion of the mutual authentication procedure.Type: GrantFiled: June 17, 2022Date of Patent: January 9, 2024Assignee: Verizon Patent and Licensing Inc.Inventors: Warren Hojilla Uy, Young R. Choi, Samirkumar Patel

Patent number: 11477036Abstract: A device receives, from an application, a request to access an attestation key stored in a secure element of the device. The device obtains an attestation policy, by which to verify an identity of the application. The device examines an application file associated with the application, to determine whether the application file satisfies the attestation policy. The device selectively generates a temporary key based on a result of examining the application file. The temporary key may be used to access the attestation key. The temporary key may be generated based on the application file satisfying the attestation policy, and may not be generated based on the application file not satisfying the attestation policy.Type: GrantFiled: August 20, 2020Date of Patent: October 18, 2022Assignee: Verizon Patent and Licensing Inc.Inventors: Manuel Enrique Caceres, Bruno Mendez, Mauricio Pati Caldeira De Andrada, Warren Hojilla Uy, Young R.

Patent number: 11444788Abstract: A method or system for authentication and access control in for network device management is disclosed. The method or system may include establishing a communication channel between a user device and a network device and receiving, by the network device, a public-key certificate including a specified identity of the user device. The method or system may include determining whether the public-key certificate is valid against a root certificate stored in the network device, and determining an actual identity of the user device. The method or system may include indicating that the user device is authentic and authorized when the received public-key is valid against the root certificate and when the actual identity of the user device matches the specified identity in the public-key certificate.Type: GrantFiled: April 13, 2020Date of Patent: September 13, 2022Assignee: Verizon Patent and Licensing Inc.Inventors: Warren Hojilla Uy, Young R.
