Abstract:
A method and a circuit for protecting an integrated circuit against an extraction of data read from at least one memory, comprising the steps of comparing each data word to be output from the integrated circuit with at least one value stored in this circuit, and generating an error signal in case of an identity between the value and the data waiting to be output.
