With the development of Internet technology, the demand for signing electronic contracts has
been greatly increased. The electronic contract generated by the participants in an online …

Multi-party fair exchange (MFE) and fair secure multi-party computation (fair SMPC) are
under-studied fields of research, with practical importance. We examine MFE scenarios …

Electronic contract signing requires the design of protocols that guarantee that the exchange
is fair. In the past 5 years, we have observed that trusted third parties (TTPs) can be replaced …

In this article, we present the first proposal for contract signing based on blockchain that
meets the requirements of fairness, hard-timeliness, and bc-optimism. The proposal, thanks …

Multi-party fair exchange (MFE) and fair secure multi-party computation (fair SMPC) are

Traditional multi-party exchange protocols need a third party to ensure fairness. It can bring
some communication costs and cryptanalytic attacks. In recent years, researchers have …

A computation scheme among n parties is fair if no party obtains the computation result
unless all other n-1 parties obtain the same result. A fair computation scheme is optimistic if …

Anonymity attracts wide attention in the electronic transaction, but participants usually do not
trust each other. The problem inspires researchers to provide fair exchange protocol based …

The great success of the Internet has raised new challenges in terms of applications and
user satisfaction. Web applications demand requirements, such as performance and …
