We propose a timed process calculus for wireless systems exposed to communication collisions. The operational semantics of our calculus is given in terms of a labelled transition ...
The idea of Conceptual Neighbourhood Diagram (CND) has proved its relevance in the areas of qualitative reasoning about time and qualitative reasoning about space. In this work, a ...
Abstract. Theories defined in a process model are formalized and studied. A theory in a process calculus is a set of perpetually available processes with finite interactability, ea...
Abstract. We formally study two privacy-type properties in online auction protocols, bidding-price-secrecy and receipt-freeness. These properties are formalised as observational eq...
Program analysis and verification tools crucially depend on the ability to symbolically describe and reason about sets of program behaviors. Separation logic provides a promising...
