Abstract: A method for detecting relay attacks between two communication platforms, the method including: receiving, at a first communication platform, a first signal sent via a first communication channel from a second communication platform, the first signal including information about a challenge; receiving, at the first communication platform, a second signal sent via a second communication channel from the second communication platform, the second signal being a start clock; receiving, at the first communication platform, a third signal sent via the second communication channel from the second communication platform, the third signal including the challenge; outputting, from the first communication platform, a response to the challenge via the first communication channel to the second communication platform; and determining, at the second communication platform, whether a relay attack has occurred based on a time elapsed from when the start clock began to when the response is received at the second communication platform.
