摘要
在分析区块链、安全多方计算的技术特点的基础上,探讨了它们技术融合的可行性。对近年来大量相关研究文献进行了多维度的梳理总结,并将其按照链上/链外安全多方计算进行分类,针对不同类别,分别提出了相应的构造模型。深入分析了基于区块链的安全多方计算的特点与优势,并从多维度对比了链上/链外安全多方计算,总结了它们的特征与应用场景,指出了未来的发展方向。
Based on the analysis of the technical characteristics of blockchain and secure multiparty computation technology,the feasibility of their technical integration was discussed.A great deal of related research literatures in recent years were combed,summarized and classified according to on-chain and off-chain secure multi-party computation.Moreover,specific construction models were proposed for each category.Finally,an in-depth analysis of the characteristics and advantages of blockchain-based secure multi-party computation was conducted.By making a comparison between on-chain and off-chain secure multi-party computation in multiple dimensions,a conclusion of their features and application scenarios was drawn and the future research direction was prospected.
