云计算下基于特殊差分方程的(m+1,t+1)门限秘密共享方案
(m + 1 ,t + 1) Threshold Secret Sharing Scheme Based on Special Difference Equation for Cloud Computing
摘要
Abstract
To solve the problem that untrusted cloud computing service providers steal user's privacy data,this paper uses the homogeneous linear difference equations with constant coeffcients as a tool,applies secret sharing technology in cloud computing,and proposes a novel (m + 1,t + 1) threshold secret sharing scheme.This scheme manages the decryption key of the user privacy data,and distributes a special secret share to user and a common secret share to each computing service provider by homogeneous linear difference equations with constant coeffcients.Cloud computing service providers cannot recover the user's privacy data without the user's involvement.Analysis reslut shows that the scheme resolves the problem that untrusted cloud computing service providers steal user's privacy data,and reduces the cost of memory overhead by optimizing secret share.关键词
