Research on trust model of universally composable security computation

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.
