Abstract
A copy is made of at least a part a stack. A caller return address of a calling function in the stack is verified as trusted. A caller return address of a called function in the stack is verified as matching a source address of the calling function in the copy of the stack. If verification is affirmative, then the called function may be executed in a trusted domain.
