一种隐私保护的多副本完整性验证方案
A Privacy-preserving Multi-copy Integrity Verification Scheme
摘要
Abstract
To make users check the integrity of cloud data in time and retrieve the data even when some part of the data are destroyed,a privacy-preserving multi-copy integrity verification scheme is proposed.The multi-copy mechanism is raised based on Parakh secret sharing scheme to ensure the data retrievability.A segment mechanism is presented to separate user's identity information and the available data.The storage authentication code is designed to establish contact between data and its owner which prevent the attackers obtaining the relationship between the user and his data.A challenge-response protocol is proposed based on multi-prover zero-knowledge proof.Analysis shows that the scheme is space efficient for cloud servers and protects the identity privacy against attackers,which resolves the problems arose by the outsource service mode of cloud computing and by the untrustworthiness of the cloud service provider.关键词
