Avispa has been successfully used in various Master’s projects. In this paper, we present two outstanding projects of quite different nature that highlight the spectrum of formal security protocol verification and lead us to a proposition of engineering practice for the development of secure protocols based on two main ideas (a) refactoring existing formalisations to prove adaptations of security protocols (b) compositional proof of new protocols allowing the combination and reuse of (parts of) existing formalisations of other protocols. This paper presents first Radius-SHA256, an adaptation of the Radius protocol for remote authentication for network access to the secure hash function SHA-256. Second, we present the Secure Simple Protocol which is an extension for security of a protocol developed at our university for next generation netw...
