Detecting Spoofed Messages Using Clock Skew
Two researchers are working on a system to detect spoofed messages sent to automobiles by fingerprinting the clock skew of the various computer components within the car, and then detecting when those skews are off. It’s a clever system, with applications outside of automobiles (and isn’t new). To perform that fingerprinting, they use a weird characteristic of all computers: tiny… Continue reading Detecting Spoofed Messages Using Clock Skew
