Abstract: An electronic device is proposed, which is configured to receive at least one cryptographic parameter and validate the at least one cryptographic parameter. The electronic device is is configured to validating the parameter by determining an imprint from a one-way function and from at least the cryptographic parameter; detecting at least one part of the imprint in a dedicated memory zone of the electronic device, and delivering a piece of information on validation should there be effective detection.
