Abstract:
System and techniques for a secure wireless lock-actuation exchange are described herein. After receiving a request to actuate a lock from a device, a controller can calculate a challenge counter and then perform verification iterations until an end condition is met—which is a failure of a verification iterations or the number of iterations reaches the challenge count. If the verification iterations reach the challenge count (e.g., there are no failed iterations), then the controller actuates the lock. Each iteration includes an exchange between the device and the controller that the device validates by signing a message with a private key shared by the device and the controller. The exchange also includes a freshness value integrated into the device validation to prevent replay attacks.

Claim (Index 1):
A controller for secure wireless lock-actuation exchange, the controller comprising:\n a lock actuator to switch a state of a lock between a first state and a second state, wherein the first state is locked and the second state is unlocked; and processing circuitry to:\n receive a request to actuate a lock from a device; \n calculate a challenge count for the request; \n perform verification iterations until an end condition is met, for each verification iteration, the processing circuitry:\n creates a vehicle signature from a freshness value and a portion of the request; \n transmits the vehicle signature to the device; \n computes a local-remote vehicle signature from the vehicle signature; and \n compares the local-remote vehicle signature to a verification signature transmitted from the device, the verification signature derived from the vehicle signature, wherein the end condition is at least one of a number of verification iterations reaching the challenge count or the comparing determining that the local-remote vehicle signature does not match the verification signature; and \n \n activate the lock actuator, to switch the state of the lock, in response to the number of verification iterations being equal to or greater than the challenge count.
