Abstract:

Traditional fuzzy comprehensive evaluation model must concentrate all the resources for calculation. A secure multi-party fuzzy comprehensive evaluation model (SMFCE) with basic properties was proposed for multiple users carrying out comprehensive evaluation in distributed environment. The proposed model allows users sharing data at different places to implement the evaluation, without leaking secret data of their own. A scheme under semi-honest model was proposed based on the theories of secure multi-party computation, which focuses on a common scenario, that is to say, many participants share fuzzy evaluation matrix by rows. Finally, the correctness and security of the scheme are proved.
