Method and apparatus to authenticate a memory module

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.

Dependencies are inferred from the claim text.
