Abstract

Embodiments of the present invention provide a cryptographic-based license management device comprising a license authority configured to generate a license in response to a product option request; an interface module having a plurality of product options that may be selectively enabled in response to a valid license issued by the license authority; a non-volatile memory associated with the interface module, the non-volatile memory module containing a programmable verification component for determining the authenticity of the license; and a license verification module associated with the interface module, the license verification module configured to verify the authenticity of a license using the programmable verification component contained within the non-volatile memory and enable selected product options provided the license is verified by the license verification module. Another feature of the present invention provides a method for cryptographic-based license management, the method comprising, generating a license in response to a product option request, the product option request identifying selected product options associated with an interface module; applying a digital signature to the license; supplying the license to an interface module; verifying the digital signature of the license with a verification component associated with the interface module; and enabling the selected product options associated with the interface module provided the digital signature of the license has been verified with the verification component.
