Abstract: 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.
