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 15):
A non-transitory machine readable medium including instructions for secure wireless lock-actuation exchange, the instructions, when executed by a machine, cause the machine to perform operations comprising:\n receiving a request to actuate a lock from a device; calculating a challenge count for the request; performing verification iterations until an end condition is met, a verification iteration comprising:\n creating a vehicle signature from a freshness value and a portion of the request; \n transmitting the vehicle signature to the device; \n computing a local-remote vehicle signature from the vehicle signature; and \n comparing 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 actuating the lock, to switch a state of the lock, in response to the number of verification iterations being equal to or greater than the challenge count, wherein the state of the lock is either a first state or a second state, and wherein the first state is locked and the second state is unlocked.
