Abstract
Smart grid embedded software is subject to intrusion and compromise with potentially serious consequences. Current methods of cybersecurity analysis are increasingly challenged by the scope the problem. Oak Ridge National Laboratory (ORNL) is pioneering the new technology of software behavior computation to help address these risks. Software behavior computation and its instantiation in Function eXtraction (FX) systems apply mathematical foundations of denotational semantics to compute the behavior of software in all circumstances of use. Research has shown how to make the effects of recursion-theoretic limitations on this process arbitrarily small. Behavior computation operates on the functional semantics of programs, and is not subject to the limitations of syntactic recognition or testing. ORNL is applying FX technology to help evaluate cyber security properties in smart grid systems, with initial focus on vulnerabilities in embedded software that controls smart meters.
