Formalising Security in Ubiquitous and Cloud Scenarios

We survey some critical issues arising in the ubiquitous computing paradigm, in particular the interplay between context-awareness and security. We then overview a language-based approach that addresses these problems from the point of view of Formal Methods. More precisely, we briefly describe a core functional language extended with mechanisms to express adaptation to context changes, to manipulate resources and to enforce security policies. In addition, we shall outline a static analysis for guaranteeing programs to securely behave in the digital environment they are part of.
