    摘要: An integrated circuit includes a communication interface circuit, a cryptographic algorithm, a countermeasure configured to protect the cryptographic algorithm against side-channel attacks, and a mask generator configured to provide the countermeasure with mask values. The integrated circuit is configured to execute a specific command requiring the disclosure of mask values used by the countermeasures to protect the cryptographic algorithm during a cryptographic session, and, in response to such a command, to send the mask values through the communication interface circuit.
