Abstract
A system and method for securing access to memory modules includes a memory module, a virtual memory module, a boot module, and a gatekeeper. The boot module accepts a key and requests for the memory module and provides the requests and the key to the virtual memory module. The virtual memory module is externally accessible by the boot module and accepts the provided key and the requests from the boot module and transmits the requests and the provided key from the boot module to the gatekeeper. The gatekeeper regulates access to the memory module allowing no other components to directly access the memory module. The gatekeeper receives the provided key from the virtual memory module and the gatekeeper authenticates the provided key by comparing it with a stored key stored in secure location. Upon proper authentication of the provided key, the gatekeeper executes the request in the memory module.
