Abstract
A secured system of remote participation in interactive games with verification of the chronology of events relies on the counting, by a secured microprocessor (for example a microcircuit card), of consecutive periods of time of which the first one (Tr12) is initialized by a cryptographically secured message sent by the transmitter and the last one (Tr25) is ended by a connection of the games machine to the central computer of the transmitter for the forwarding thereto of the answer.
