Abstract: Systems and methods for preventing digital key relay attacks are provided. A method includes determining a threshold response time for a wireless communications device to process a challenge. Determining the threshold response time may include determining a benchmark response time for the wireless communications device to respond to the challenge based on one or more conditions of the wireless communications device, and setting the threshold response time to the benchmark response time. The method further includes sending the challenge to the wireless communications device. The method further includes receiving a response to the challenge from the wireless communications device within a response time. The method further includes authenticating the wireless communications device based on the response time being less than the threshold response time. Associated systems are also provided.

Abstract: An example operation includes one or more of downloading an update of a non-volatile electrically erasable memory storage of a vehicle, determining whether the memory storage is arranged in one of a block of bytes of memory and an individual byte of memory, selecting a programming protocol based on the memory storage arrangement and writing the memory storage based on the selected programming protocol.
