A high-level security policy states an overall safety requirement for a sensitive task. One example of a high-level security policy is a separation of duty policy, which requires ...
Valiant has proposed a new theory of algorithmic computation based on perfect matchings and Pfaffians. We study the properties of matchgates—the basic building blocks in this n...
