Abstract (en)
[origin: WO2019110945A1] The invention relates to an integrated circuit comprising: one or more protected circuits (IP1 to IPN); a license control circuit (110) designed to ask a license issuer (104) for a license to activate said one or more protected circuits, the license request comprising a germ value (SEED); and a cryptographic circuit (120) designed to verify the authenticity of a license received from the license issuer on the basis of the germ value, the license control circuit (110) being designed to impose a validity limit on the received licenses, and to ask the license issuer for a new license before the validity limit of the received license.
