Abstract
This disclosure describes approaches for securing memory among non-secure/secure processing environments such as in a TrustZone-M processor architecture. An example method of controlling memory access includes: configuring a memory locking service in a computing device having a secure processing environment and a non-secure processing environment, and executing the memory locking service in the secure processing environment; receiving a request with the memory locking service to lock a specified memory region of the computing device, with the specified memory region being associated with the non-secure processing environment; associating the specified memory region with the secure processing environment (e.g., by using a Security Attribution Unit to upgrade the region to secure memory); subsequently, identifying an access attempt to the specified memory region, with the access attempt being received from the non-secure processing environment; and controlling the access attempt to the specified memory region, based on a policy.
