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 21):
The machine readable medium of  claim 20 , wherein computing the local-remote vehicle signature includes computing a second MAC using the key and the vehicle signature.
