Abstract

An information handling system includes a first memory having a trusted memory region, wherein the trusted memory region is an area of execution that is protected from processes running in the information handling system outside the trusted memory region. A secure cryptographic module may receive a request to create the trusted memory region from a dependent application, and create a mapping of the trusted memory region along with an enhanced page cache address range mapped to a non-uniform memory access (NUMA) node. The module may also detect a NUMA migration event of the dependent application, identify the trusted memory region corresponding to the NUMA migration event, and migrate the trusted memory region from the NUMA node to another NUMA node.
