Abstract
Secrecy properties of network protocols assert that no probabilistic polynomial-time distinguisher can win a suitable game presented by a challenger. Because such properties are not determined by trace-by-trace behavior of the protocol, we establish a trace-based protocol condition, suitable for inductive proofs, that guarantees a generic reduction from protocol attacks to attacks on underlying primitives. We use this condition to present a compositional inductive proof system for secrecy, and illustrate the system by giving a modular, formal proof of computational authentication and secrecy properties of Kerberos V5.
