Combining behavioural types with security analysis

• Survey of behavioural types for secure communications.
• Review of logical foundations for behavioural types with applications to security.
• Overview of behavioural types for protecting trusted parties in untrusted contexts.

Today's software systems are highly distributed and interconnected, and they increasingly rely on communication to achieve their goals; due to their societal importance, security and trustworthiness are crucial aspects for the correctness of these systems. Behavioural types, which extend data types by describing also the structured behaviour of programs, are a widely studied approach to the enforcement of correctness properties in communicating systems. This paper offers a unified overview of proposals based on behavioural types which are aimed at the analysis of security properties.
