We present a symbolic framework for refinement and compositi on of security protocols. The framework uses the notion of ideal f unctionalities. These are abstract systems which are secure by construction and wh ich can be combined into larger systems. They can be separately refined in order t o obtain concrete protocols implementing them. Our work builds on ideas from comp utational models such as the universally composable security and reactive si mulatability frameworks. The underlying… CONTINUE READING
