摘要/Abstract

摘要： 从通用可组合(UC)框架的基本概念出发，分析UC安全性对承诺协议的要求，得出以下结论：朴素模型中不存在UC安全承诺协议是因为承诺协议的安全需求与UC安全性要求间存在矛盾。在此基础上提出一种基于防篡改硬件模型的UC安全承诺协议UCCOM。分析结果表明，UCCOM的安全性不依赖于可信第三方，与同类协议相比，使用的密码学操作更少，效率更高。

Abstract: Beginning with the research of the basic concepts of Universally Composable(UC) framework, the requirement of UC security on commitment protocols is analyzed in this paper, and the reason of the problem that all UC commitment protocols do not exist in the plain model is pointed out that the security requirement of commitment protocol and the requirement of UC security are contradictory. On the basis of this, a UC secure commitment protocol UCCOM using tamper-proof hardware is proposed. Analysis result shows that UCCOM does not depend on any trusted third-party and uses fewer cryptographic operations compared with the related works, so it has higer efficiency.

Key words: commitment protocol, Universally Composable(UC) security, tamper-proof hardware, hiding property, binding property
