On unifying some cryptographic protocol logics
Paul F. Syverson, Paul C. van Oorschot · 2002
We present a logic for analyzing cryptographic protocols. This logic encompasses a unification of four of its predecessors in the BAN family of logics, namely those given by Li Gong et al. (1990); M. Abadi, M. Tuttle (1991); P.C. van Oorschot (1993); and BAN itself (M. Burrows et al., 1989). We also present a model-theoretic semantics with respect to which the logic is sound. The logic presented captures all of the desirable features of its predecessors and more; nonetheless, it accomplishes this with no more axioms or rules than the simplest of its predecessors.>
