Abstract
In an embodiment, at least one machine-readable storage medium includes instructions that when executed enable a system to receive, at a special library of a parent process located outside of a parent protected region of the parent process, from the parent protected region of the parent process, a call to create a child process and responsive to the call received at the special library, issue by the special library a first request and a second request. The first request is to execute, by a processor, a non-secure instruction to create the child process. The second request is to execute, by the processor, a first secure instruction to create a child protected region within the child process. Responsive to the first request the child process is to be created and responsive to the second request the child protected region is to be created. Other embodiments are described and claimed.
