Fair and optimistic quantum contract signing
We present a fair and optimistic [7, 8] quantum contract signing protocol between two clients that requires no communication with the third trusted party during the exchange phase. We discuss its fairness and show that it is possible to design such a protocol for which the probability of a dishonest client to cheat becomes negligible, and scales as N−1/2, where N is the number of messages excha...
متن کاملAbuse-Free Optimistic Contract Signing
We introduce the notion of abuse-free distributed contract signing, that is, distributed contract signing in which no party ever can prove to a third party that he is capable of choosing whether to validate or invalidate the contract. Assume Alice and Bob are signing a contract. If the contract protocol they use is not abuse-free, then it is possible for one party, say Alice, at some point to c...
متن کاملOptimistic Asynchronous Multi-Party Contract Signing
A contract is a non-repudiable agreement on a given contract text, i.e., it can be used to prove unanimous agreement between its signatories to any veri er. A contract signing protocol is used to fairly compute a contract so that, even if n 1 of the n signatories misbehave, either all or none of them obtain a contract. Optimistic contract signing protocols use a third party to ensure fairness, ...
متن کاملQuantum contract signing
We present a probabilistic quantum contract signing protocol between two clients that requires no communication with the third trusted party during the commitment (i.e. signature exchange) phase. We discuss its fairness and show that it is possible to design such a protocol for which the probability of a dishonest client to cheat becomes negligible, and scales as N−1/2, where N is the size of t...
متن کاملLegally Fair Contract Signing Without Keystones
In two-party computation, achieving both fairness and guaranteed output delivery is well known to be impossible. Despite this limitation, many approaches provide solutions of practical interest by weakening somewhat the fairness requirement. Such approaches fall roughly in three categories: “gradual release” schemes assume that the aggrieved party can eventually reconstruct the missing informat...
