Hoare and He’s Unifying Theories of Programming (UTP) provides a rich model of programs as relational predicates. This theory is intended to provide a single framework in which any programming paradigms, languages, and features, can be modelled, compared and contrasted. The UTP already has models for several programming formalisms, such as imperative programming, higher-order programming (e.g. ...

Assumption{Commitment paradigms for speciication and veriication of concurrent programs have been proposed in the past. We show that two typical parallel composition rules for shared variable and message passing programs 8, 12] which hitherto required diierent formulations are instances of one general rule mainly inspired by Abadi & Lamport's composition theorem 1].

We study an extension of the well-known Abadi-Rogaway logic with hashes. Previously, we have shown that it is possible to give a sound computational interpretation of this extension in the standard model using Canetti’s oracle hashing. This paper extends Micciancio and Warinschi’s completeness result for the original logic to this setting.

The object calculus of Abadi and Cardelli [AC96, AC94b, AC94a] is intended as model of central aspects of object-oriented programming languages. In this paper we encode the object calculus in the asynchronous π-calculus without matching and investigate the properties of our encoding.

Context. The object calculi of Abadi and Cardelli provide idealized models of object-oriented programming languages [1]. They have rigorously defined semantics, and they are simple since only objects are considered as primitives. At the same time they are expressive enough to encode all common features of practical (i.e., class-based) object-oriented programming languages like classes, subtypin...

We present a model of Linear Abadi and Plotkin Logic for parametricity [8] based on the operational semantics of LILY, a polymorphic linear lambda calculus endowed with an operational semantics [3]. We use it to formally prove definability of general recursive types in LILY and to derive reasoning principles for the recursive types.

We onsider an obje t al ulus of Abadi and Leino. The language has a type system with obje t subtyping whi h allows for spe ialisation, ovariant subtyping in the return types of methods and invariant subtyping in the types of elds. We present a type inferen e algorithm for this language.

This paper provides one more step towards bridging the gap between the formal and computational approaches to cryptographic protocols. We extend the well-known Abadi-Rogaway logic with probabilistic hashes and we give precise semantic to it using Canetti’s oracle hashing. Finally, we show that this interpretation is computationally sound.
