Practical Implementations of a Non-disclosure Fair Contract Signing Protocol
Contract signing is a practical application of the fair exchange of digital signatures. This application used to be realized by directly adopting the results of the fair exchange of signatures, which do not completely meet the requirements of the signing of a secret contract. The assistance of a trusted third party (TTP) and some cryptographic technology are required to allow two parties to exc...
متن کاملA Novel Fair GSR Contract Signing Protocol Against Earnest Money
In this paper we propose a novel Fair Gradual Secrete Release (GSR) protocol for E-contract signing against earnest money between an originator and a responder involving their banks as transacting parties. We provide a security analysis of the protocol and analyze some important and pertinent properties of the protocol, which include money atomicity, validated contract and the fairness in true ...
متن کاملAnalysis and Improvement of Micali's Fair Contract Signing Protocol
In PODC 2003, Micali presented a fair electronic exchange protocol for contract signing with an invisible trusted party [17]. The protocol was filed as a US patent No 5666420 in 1997 [16]. In the protocol, two mutually distrusted parties exchange their commitments to a contract in a fair way such that either each of them can obtain the other’s commitment, or neither of them does. The protocol i...
متن کاملFair 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 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...
