摘要: 通用可组合(UC)安全计算的存在性需要刻画某种基础假定的信任模型的支持。针对国内对于UC安全计算的信任模型研究甚少的现状,研究了UC安全性的本质要求及其对UC安全计算的限制,得出了使用这些信任模型的根本原因,进而分析了国外用来刻画这些基础假定的信任模型的设计原理,比较了它们的异同和优缺点,并展望了未来的研究方向。

Abstract: A trust model capturing some set-up assumptions is necessary to guarantee the existence of Universally Composable (UC) security computation. Little domestic research on the trust model of UC security computation has been made. In this paper, the essential requirement of UC security and its limitation on UC security computation were researched to find out why these set-up assumptions were used. And then overseas representative trust models were analyzed and their merits and demerits were compared respectively. Finally, the research trend in future was pointed out.

Key words: cryptographic protocol, Universally Composable (UC), security computation, set-up assumption, trust model
