  • Patent number: 9455839
    Abstract: 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.

  • Publication number: 20160116510
    Abstract: Disclosed herein are methods, systems, and computer-readable media for operating an electronic locking device. The disclosed methods include a method of predicting a battery life of an electronic locking product based at least in part on a usage history of the electronic locking product. The predicted battery life may include an adjustment based on received weather information relating to a location of the electronic locking device. The disclosed methods include a method of sharing an unlocking code to an electronic locking product by a first user to a second user.

  • Publication number: 20160036788
    Abstract: Disclosed are methods, and devices for wireless key management for authentication. One method includes receiving a lock identifier from a locking device; determining that the lock identifier is associated with a user profile, wherein a user profile is authenticated and encrypted by a server using a lock key that is stored by the server and the locking device, and wherein the user profile comprises a user key; transmitting the user profile; decrypting the user profile using the lock key; transmitting a security code; generating an encrypted command comprising the security code and encrypted using the user key; transmitting the command; validating the command. Validating the command can include decrypting using the user key; determining whether the security code is valid; and authenticating using the user key; and initiating, in response to validating, an action of the locking device as specified by the command.

  • Publication number: 20160035163
    Abstract: Disclosed are methods, systems, and computer-readable media for tracking location of locking devices. One locking device includes a wireless transceiver, a memory, an electronically controllable locking mechanism, a processor, and a location determination circuit configured to determine a location of the electronic locking device. The processor is configured to receive one or more location data items indicating the location of the electronic locking device at one or more times, to store the one or more location data items in the memory, and to transmit the one or more location data items from the memory to a mobile device via the wireless transceiver.

  • Publication number: 20160036814
    Abstract: Disclosed are methods and devices for securely updating firmware of locking devices. One method includes receiving a lock identifier from a locking device; determining that the lock identifier is associated with a user profile by comparing the lock identifier to a set of lock identifiers; receiving a firmware update packet from a server, wherein the firmware packet is encrypted by a lock key; transmitting the firmware update packet to the lock; decrypting the firmware update using the lock key; validating the encrypted firmware update; and installing the firmware update.
