The increasing interest in telecommunication systems and the wide spreading of computer networks within commercial and scientific field, are going in the direction of a deep integration of phone and data systems into a single network infrastructure. We are particular interested in security issues that arise in such context, thinking, for example, about authentication and billing problems. The a...
