Rerandomizing ciphertexts plays an important role in protecting privacy in security protocols such as mixnets. We investigate the relationship between formal and computational approaches to the analysis of the security protocols using a rerandomizable encryption scheme. We introduce a new method of dealing with composed randomnesses in an Abadi-Rogaway-style pattern, formalize a rerandomizable ...

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].

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. ...

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...
