Language, Semantics, and Methods for Cryptographic Protocols
Federico Crazzolara
August 2000 |
Abstract:
In this report we present a process language for security
protocols together with an operational semantics and an alternative semantics
in terms of sets of events. The denotation of process is a set of events, and
as each event specifies a set of pre and postconditions, this denotation can
be viewed as a Petri net. This Petri-net semantics has a strong relation to
both Paulson's inductive set of rules and the strand space approach. By means
of an example we illustrate how the Petri-net semantics can be used to prove
properties such as secrecy and authentication
