Universally composable secure multiparty computation protocol with fairness
摘要
Abstract
The fair problem of secure multiparty computation protocol was investigated in the universally composable framework. A fair secure multiparty computation model with ideal functionalities was firstly formulated such as a fair secure multiparty addition computation and a fair secure multiparty multiplicative computation. Next a fair addition computation protocol and a fair multiplicative computation protocol based on the bilinear paring and the ideal functionality of a commit-ment scheme was proposed. The proposed protocols can securely realize their ideal functionalities in the hybrid model re-spectively. Finally, analysis show that these schemes are effective, and it can be more applicable in special situation.关键词
