07421 Abstracts Collection – Formal Protocol Verification Applied

Authors: Liqun Chen, Steve Kremer, and Mark D. Ryan

Abstract
From 14/10/2007 to 19/10/2007, the Dagstuhl Seminar 07421 ``Formal Protocol Verification Applied'' was held in the International Conference and Research Center (IBFI), Schloss Dagstuhl. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abstracts of seminar results and ideas are put together in this paper. The first section describes the seminar topics and goals in general. Links to extended abstracts or full papers are provided, if available.

07421 Executive Summary – Formal Protocol Verification Applied

Authors: Liqun Chen, Steve Kremer, and Mark D. Ryan

Abstract
Security protocols are a core part of distributed computing systems, and are part of our everyday life since they are used in web servers, email, mobile phones, bank transactions, etc. However, security protocols are notoriously difficult to get right. There are many cases of protocols which are proposed and considered secure for many years, but later found to have security flaws. Formal methods offer a promising way for automated security analysis of protocols. While there have been considerable advances in this area, most techniques have only been applied to academic case studies and security properties such as secrecy and authentication. The seminar brought together researchers deploying security protocols in new application areas, cryptographers, and researchers from formal methods who analyse security protocols. The interaction between researchers from these different communities aims to open new research topics, e.g., identify new security properties that need verification and refine abstractions of the abstract models of crytpographic primitives.

Complete Characterization of Security Protocols by Pattern Refinement

Authors: Cas Cremers

Abstract
Recently, the notion of complete characterizations of security protocols was introduced by Guttman and Thayer. We provide an alternative definition of this concept, and extend an existing protocol verification tool (Scyther) to compute our notion of complete characterization. We present both notions of complete characterization, discuss their relative merits, and provide preliminary empirical results using an extended version of the Scyther tool.

Zero-Knowledge in the Applied Pi-calculus and Automated Verification of the Direct Anonymous Attestation Protocol

Authors: Michael Backes, Matteo Maffei, and Dominique Unruh

Abstract
We devise an abstraction of zero-knowledge protocols that is accessible to a fully mechanized analysis. The abstraction is formalized within the applied pi-calculus using a novel equational theory that abstractly characterizes the cryptographic semantics of zero-knowledge proofs. We present an encoding from the equational theory into a convergent rewriting system that is suitable for the automated protocol verifier ProVerif. The encoding is sound and fully automated. We successfully used ProVerif to obtain the first mechanized analysis of the Direct Anonymous Attestation (DAA) protocol. The analysis in particular required us to devise novel abstractions of sophisticated cryptographic security definitions based on interactive games.
