Distance-Bounding Protocols: Verification without Time and Location

Distance-bounding protocols are cryptographic protocols that securely establish an upper bound on the physical distance between the participants.

Existing symbolic verification frameworks for distance-bounding protocols consider timestamps and the location of agents.

In this work we introduce a causality-based characterization of secure distance-bounding that discards the notions of time and location.

This allows us to verify the correctness of distance-bounding protocols with standard protocol verification tools. That is to say, we provide the first fully automated verification framework for distance-bounding protocols.

By using our framework, we confirmed known vulnerabilities in a number of protocols and discovered unreported attacks against two recently published protocols.
