Abstract

Under the cloud computing environment, the privacy-preserving fuzzy comprehensive evaluation problem is proposed and solved, which has not been studied in the area of secure multi-party computation. Besides, through the analysis of the protocol's security, an improved protocol whose security is higher is given based on blind-and-permute protocol and privacy-preserving protocol of finding the maximum component's position, whose security is stated using the simulation paradigm at last. The experimental results map out the correct possibilities for our algorithm.
