传统的模糊综合评判模型必须集中所有数据进行计算.为了解决分布式环境中多个用户在不共享各自隐私数据的情况下完成综合评判的问题,提出了安全多方模糊综合评判(SMFCE)模型及其主要性质.该模型允许多个分享数据的用户分处不同地点完成评判过程,并且不泄露各自持有的数据.然后,针对参与方按行分享模糊评价矩阵的情形,基于安全多方计算理论,设计出半诚实模型下SMFCE协议.最后,对协议的正确性和安全性进行了证明.
Traditional fuzzy comprehensive evaluation model must concentrate all the resources for calculation. In order to solve the problem that multiple users carry out comprehensive evaluation in distributed environment without sharing private data, a secure multi-party fuzzy comprehensive evaluation (SMFCE) model with basic properties is proposed to allow users sharing data at different places to implement the evaluation without leaking secret data of their own. A protocol under semi-honest model is proposed based on the theory of secure multi-party computation focusing on a common scenario, that is to say, many participants will share fuzzy evaluation matrix by rows. Finally, the correctness and security of the protocol are proved.
