Abstract:
A method of secure function execution is performed in a computer system (100) running an operating system platform having an operating systenm including a kernel space (114) and a process space (112) including a user application running in the process space (112). A system call is intercepted (190) and examined for validity (196) by comparing the intercepted system call originating address with a range of process valid addresses associated with a process (194).
