Non-repudiation protocols have an important role in many areas where secured transactions with proofs of participation are necessary. Formal methods are clever and without error, therefore using them for verifying such protocols is crucial. In this purpose, we show how to partially represent non-repudiation as a combination of authentications on the Fair Zhou-Gollmann protocol. After discussing...
The paper discusses an experience in using Unified Modelling Language and two complementary verification tools in the framework of SAFECAST, a project on secured group communication systems design. AVISPA enabled detecting and fixing security flaws. The TURTLE toolkit enabled saving development time by eliminating design solutions with inappropriate temporal parameters.
Avispa is now a commonly used verification tool for cryptographic protocols. The main advantage of this tool is the ability to use different verification techniques on the same protocol specification. In this paper, we present a protocol animator designed to help protocol developers in writing AVISPA specifications. This is the result of an ongoing joint experiment with Thomson R&D to use AVISP...
AVISPA is a push-button tool for the automated validation of Internet security-sensitive protocols and applications. It provides a modular and expressive formal language for specifying protocols and their security properties, and integrates different back-ends that implement a variety of state-of-the-art automatic analysis techniques. To the best of our knowledge, no other tool exhibits the sam...
En este artículo presentamos un análisis comparativo de algunos cálculos de computación móvil propuestos recientemente. Al tiempo que se describen el cálculo propuesto por Milner en [RMW92], un cálculo de ambientes propuesto por Cardelli y Gordon en [CG98] y PiCO; un cálculo de objetos y restricciones propuesto por el grupo AVISPA 1 en [ADQ00], se comparan entre ellos y se comentan sus principa...
Non-repudiation protocols with session labels have a number of vulnerabilities. Recently Cederquist, Corin and Dashti have proposed an optimistic non-repudiation protocol that avoids altogether the use of session labels. We have specified and analysed this protocol using an extended version of the AVISPA Tool and one important fault has been discovered. We describe the protocol, the analysis me...
