Abstract: Methods, apparatus, systems and articles of manufacture (e.g., physical storage media) to implement license management solutions for software defined silicon (SDSi) products are disclosed. Example license management solutions disclosed herein include, but are not limited to, virtual resource migration using SDSi, resource configuration management using SDSi, hardware self-configuration using SDSi, reduced footprint agents using SDSi, performing SDSi usage evaluation and corresponding license transfer responsive to detected and/or predicted failures, transferring node locked SDSi licenses, transfer of SDSi licenses without a trusted license server, community license generation, expirable SDSi licenses via a reliable clock, non-node locked licenses via blockchain, and activating hardware features with a pre-generated hardware license.

Abstract: The present disclosure is directed to an authentication system, tools, and methods for authentication including a first inspection tool that generates first images for a first inspection of a device, and a first processor for processing the first images using a hashing algorithm, for which the first inspection tool and the first processor are sited at a first location, and a second inspection tool that generates second images for a second inspection of the device, and a second processor for processing the second images using the hashing algorithm, for which the second inspection tool and the second processor are sited at a second location. The second processor compares the first and second sets of hash values to authenticate the device as being authentic and untampered.

Abstract: A first semiconductor device includes a processor configured to generate a random number at initial test of a second semiconductor device after fabrication of the second semiconductor device in a supply chain related to the second semiconductor device, and send the generated random number to the second semiconductor device. The processor is further configured to receive a first signature that is signed over the sent random number by the second semiconductor device using a first private key that is stored in the second semiconductor device, among a first private and public key pair, and test the received first signature, using a first public key that is stored in the first semiconductor device, among the first private and public key pair, to determine whether the second semiconductor device is authenticated.
