Patent number: 10262484Abstract: Disclosed are methods, systems, and computer-readable media for wireless key management for authentication. Authentication includes transmitting a request to a locking device, transmitting a security challenge to the mobile device, and transmitting a response to the challenge and an encrypted user profile for the locking device. The response includes data generated with an access key that is stored by both the mobile device and the locking device, and the user profile is encrypted by a server using a secret key that is stored by the server and the locking device. Authentication further includes verifying the response to the challenge, where the response is verified using the access key, and validating additional data from the mobile device. An action of the locking device may be initiated as specified by the request.Type: GrantFiled: May 4, 2017Date of Patent: April 16, 2019Assignee: Master Lock Company LLCInventors: Nathan Conrad, Yi Zhang, Nemanja Stefanovic, John Bartucci, Scott Kalous
