Abstract

A method and a circuit for protecting data contained in an electronic circuit against a disturbance of its operation, in which a detection of a disturbance conditions the incrementing or the decrementing of a counter over at least one bit, the counter being automatically reset at the end of a time period independent from the fact that the circuit is or not powered.
