Abstract
A method for discovering emulated clients. A verifier sends a cryptographic challenge C to a client and preferably starts a timer. The client uses a deterministic key search algorithm to find the correct key and returns the result as a number of tries needed. The verifier then stops the timer if this was started and verifies that the result is correct and preferably that the response was timely. Also provided is a verifier.
