Abstract
We develop a typed process calculus for security protocols in which
types convey secrecy properties. We focus on asymmetric communication

and \private" keys) with dierent levels of secrecy and scopes.
1 Introduction
A secret is something you tell to one person at a time, according to a popular
denition. Research on security has led to several other concepts of secrecy
