Abstract
Systems and methods are provided for a secondary authentication of a memory module. A nonce key is written to a nonce register of a register array on the memory module, the nonce register being accessible over two different interfaces. In various embodiments, the nonce key may be generated by a management system of the computing platform after performing one or more authentication processes for a memory module over a management interface. Authentication information for use in performing authentication can be stored in an identification component on the memory module. If authentication is successful, the management system can generate the nonce key and write it to the nonce register. Upon receiving a request to access an address, a memory controller can read the nonce register of the memory module at the requested address and compare the nonce key to an identifier included in the request.
