恶意模型下公平的安全两方计算协议

Fair and Secure Two-Party Computation Protocol in the Malicious Model

安全多方计算通过参与者自行进行信息交互和计算完成,信息交换和计算对协议的公平性有很大影响。在恶意模型下基于m/2-out-of-m方法和知识承诺方案,提出一种两方公平交换协议,并用该协议构造一个满足公平性的安全两方计算协议。

Secure multi-party computation is achieved through exchanging information and computation, so exchange and computation has great impact on fairness. This paper proposed a fair two-party exchange protocol based on m/2 - out - of- m technical and the knowledge commitment in malicious model, and then constructed a secure two-party computation protocol with fairness.
