Security and trust are two properties of modern computing systems that are the focus of much recent interest. They play an increasingly significant role in the requirements for mo...
We survey formal methods as they are applied to the development of communication services. We report on industrial and academic projects, consider di erent communication architect...
We highlight the limitations of formal methods by exhibiting two results in recursive function theory: that there is no effective means of finding a program that satisfies a given...
We have recently completed the specication and security proof of a large, industrial scale application. The application is security critical, and the modelling and proof were done ...
Security-critical systems are an important application area for formal methods. However, such systems often contain cryptographic subsystems. The natural definitions of these subsy...
