Abstract: Highlights•We analyze how to generate the same random token from an ECG in two different sensors.•Two sensors cannot derive a common token by applying an error correction technique.•We propose a timed automaton to synchronize two ECG sensors.•To generate a 32, 64 and 128 bits tokens, sensors should wait 13, 28 and 56.5 seconds.•We have developed a proof-of-concept implementation of an ECG-based token generator.
