..... 19 Introduction 1 1 Introduction There are various approaches to proving the safety of authentication protocols, including special belief logics like BAN [1] model checking [2, 3] and theorem proving. Most theorem proving and model checking has been based on trace histories [4, 5], in particular using CSP and its trace model [6] In this paper we demonstrate that a simpler approach based on sets of events can suffice to prove safety properties of authentication protocols. Sets have some advantages over sequences in that they carry less information. They therefore reduce ....
....His work is considerably more extensive and he discusses other protocols such as Otway Rees. Paulson uses the Isabelle HOL prover and has considerably automated his proofs. For N S he proves the presence of the other agent and our secret1 and secret2 lemmas. These two lemmas are, as Butler [5] points out, the critical properties. But it seems useful to be assured that messages are not being read by third parties, rather than merely to be assured that any such eavesdroppers must be honest. The RAISE justification editor has no facility for replay and only a limited amount of ....
