Dimitriou和Michalas最近提出了一种分散的安全协议，用于在声誉系统中铸造信任评级（StR协议），并且StR协议被证明比以前提供匿名反馈的工作更快。本文提出了StR协议的一种新的增强方案，与StR协议相比，新方案具有完全相同的安全性，但处理时间和通信开销都减少了一半。因此，我们在不牺牲任何安全性的情况下提高了性能，特别是通信延迟大大减少。关键词：声誉评价，分散环境
SUMMARY A decentralized secure protocol for casting trust rating in reputation systems (StR protocol) is lately proposed by Dimitriou and Michalas, and the StR protocol is verified to be faster than the previous work providing anonymous feedback. In this letter, we present new enhanced scheme of StR. Compared with StR protocol, our new approach at-tains the exactly same security, but requires less processing time and about half communication overheads. Therefore, we improve the performance without sacrificing any security, especially the communication delay is dramatically reduced. key words: reputation evaluation, decentralized environment
