Abstract
This disclosure describes approaches for sandboxing a thread and memory resources within non-secure/secure processing environments such as in a TrustZone-M processor architecture. An example method of controlling memory access includes: providing 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 establish a sandbox for a particular thread that executes in the non-secure processing environment and is associated with at least one specified memory region; and associating other threads of the non-secure processing environment with the secure processing environment, such that the particular thread is unable to access memory resources of the other threads while the particular thread is sandboxed.
