Current standard security practices do not provide substantial assurance that the end-to-end
behavior of a computing system satisfies important security policies such as confidentiality …

Mobile systems, whose components communicate and change their structure, now pervade
the informational world and the wider world of which it is a part. The science of mobile …

Our society's widespread dependence on networked information systems for everything from
personal finance to military communications makes it essential to improve the security of …

We study and further develop two language-based techniques for analyzing security
protocols. One is based on a typed process calculus; the other, on untyped logic programs …

We propose a general, powerful framework of type systems for the π-calculus, and show that
we can obtain as its instances a variety of type systems guaranteeing non-trivial properties …

We propose a type system to ensure the property of noninterference in a system of
concurrent programs, described in a standard imperative language enriched with …

We introduce a typed π-calculus where strong normalisation is ensured by typability. Strong
normalisation is a useful property in many computational contexts, including distributed …

In today's world of the Internet, the World-Wide Web, and Google, information is more
accessible than ever before. An unfortunate corollary is that it is harder than ever to protect …

We propose a new type system for information flow analysis for the π-calculus. As
demonstrated by recent studies, information about whether each communication succeeds …

In this paper, we develop a novel notion of dependent information flow types. Dependent
information flow types fit within the standard framework of dependent type theory, but, unlike …
