Abstract

An electronic lock that interacts with a mobile device is presented. In accordance with some embodiments, an electronic lock includes a wireless power receiver configured to receiver power from a mobile device; a processor coupled to receive power from the wireless power receiver; a memory coupled to the processor and to receive power from the wireless power receiver; a communication unit coupled to the processor and to receive power from the wireless power receiver, the communication unit configured to communicate with the mobile device; and an actuator coupled to the processor and to receive power from the wireless power receiver. The processor executes instructions stored in a memory for authenticating the mobile device, and providing signals to the actuator according to instructions received from the mobile device once it is authenticated. The mobile device provides power to the electronic lock and instructs it to lock or unlock a locking mechanism.

First claim

What is claimed is:

1. A mobile device configured to interact with an electronic lock, the mobile device comprising:
a wireless power receiver/transmitter;
a power storage coupled to the wireless power receiver/transmitter;
a processor coupled to the wireless power receiver/transmitter;
a communications coupled to the processor; and
a memory coupled to the processor,
wherein the processor executes instructions stored in the memory for
providing power to the electronic lock,
receiving a pseudo-random number from the electronic lock,
convoluting the pseudo-random number with a pairing key to generate a device session key,
transmitting the device session key to the electronic lock, and
providing instructions to the electronic lock to open or close a locking mechanism once the electronic lock validated the mobile device.

2. The mobile device of claim 1 , wherein the instructions stored in memory further include instructions for pairing the mobile device with the electronic lock to generate the pairing key.

3. A method of operating a mobile device to interact with an electronic lock, comprising:
providing power to the electronic lock,
receiving a pseudo-random number from the electronic lock,
convoluting the pseudo-random number with a pairing key to generate a device session key,
transmitting the device session key to the electronic lock, and
providing instructions to the electronic lock to open or close a locking mechanism once the electronic lock validated the mobile device.

4. The mobile device of claim 1 , wherein the instructions stored in memory further include instructions for pairing the mobile device with the electronic lock to generate the pairing key.
