  • System and method for licensing and for measuring use of an IP block
    Patent number: 11562050
    Abstract: An integrated circuit includes: one or more protected circuits; a license control circuit configured to request, from a license issuer, a license for activating the one or more protected circuits, the license request having a seed value; and a cryptographic circuit configured to verify the authenticity of a license received from the license issuer based on the seed value, wherein the license control circuit is configured to impose a validity limit on the received license, and to request a new license from the license issuer before the validity limit of the received license.

  • System and method for authenticating and IP licensing of hardware modules
    Patent number: 11023621
    Abstract: The invention relates to a license-verification circuit for selectively activating one or more protected circuits (206) of a device (102) the license-verification circuit being capable of: deducing a device key from an identifier associated with the device (102); receiving a first license; decrypting the first license using the device key in order to extract a first verification code activating a first protected circuit by loading an activation code in an activation log (212) associated with the first protected circuit on the basis of a verification of the first verification code.
