Secure Multi-Party Fuzzy Comprehensive Evaluation Model and Its Protocol
Kangfeng Zheng · Beijing Youdian Xueyuan xuebao · 2009
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.
