A Dolev-Yao-Based Definition of Abuse-Free Protocols

The authors propose a Dolev-Yao-based definition of abuse freeness for optimistic contract-signing protocols which, unlike other definitions, incorporates a rigorous notion of what it means for an outside party to be convinced by a dishonest party that it has the ability to determine the outcome of the protocol with an honest party, i.e., to determine whether it will obtain a valid contract itself or whether it will prevent the honest party from obtaining a valid contract. Their definition involves a new notion of test (inspired by static equivalence) which the outside party can perform.
