    摘要： A method is provided for securely provisioning a plurality of integrated circuits (ICs) manufactured by a first entity for use in a plurality of manufactured product types manufactured by a second entity. Each IC of the plurality of ICs includes a key pair and a unique identifier (UID). The first entity generates a plurality of key pairs that are not related to the plurality of ICs. A plurality of product types is received from the second entity. A plurality of certificates is generated by the first entity using the UIDs and the key pairs. The plurality of certificates is transferred from a first computer system of the first entity to a second computer system under physical control of the second entity. The second entity injects the plurality of ICs with selected certificates of the plurality of certificates. Unused certificates may be deleted from the second computer system.

    摘要： A cryptographic hash based on content of a Sideband Bus Device (SPD) Hub and serial number identifiers for components on a memory module is provided. The cryptographic hash provides the ability to mitigate various supply chain attacks by binding the SPD Hub content to a memory module certificate that is used for authentication. Based on the cryptographic signatures, a certificate is trusted by the platform so the binding of the SPD hub content to the memory module certificate creates a secure way to ensure the components on the memory module have not been tampered with and that the reported attributes of the memory module are correct.
