抗理性敌手共谋的安全K-prototype聚类
Secure K-prototype clustering against the collusion of rational adversaries
摘要
Abstract
Aiming at the problem of data privacy leakage in cloud environment and collusion between cloud servers in the process of clustering,an cooperative secure K-prototype clustering scheme(CSKC)against the adversaries of rational collusion is proposed.First,considering that homomorphic encryption does not directly support nonlinear computing,secure computing protocols are designed based on homomorphic encryption and additive secret sharing to ensure that the input data and intermediate results are in the form of additive secret share,and to achieve accurate calculation of the security comparison function.Second,according to the game equilibrium theory,a variety of efficient incentive mechanisms are designed,and the mutual condition contract and report contract are constructed to constrain cloud servers to implement secure computing protocols honestly and non-collusively.Finally,the proposed protocols and contracts are analyzed theoretically,and the performance of the CSKC scheme is verified by experiment.Experimental results show that compared with the model accuracy in plaintext environment,the model accuracy loss of the CSKC scheme is controlled within 0.22%.关键词
