Public Integrity Auditing for Shared Dynamic Cloud Data with Group User Revocation
Abstract— Public Integrity Auditing for Shared Dynamic Cloud Data with Group User Revocation. The advent of the cloud computing makes storage outsourcing become a rising trend, which promotes the secure remote data auditing a hot topic that appeared in the research literature. Recently some research consider the problem of secure and efﬁcient public data integrity auditing for shared dynamic data. However, these schemes are still not secure < Final Year Projects 2016 > the collusion of cloud storage server and revoked group users during user revocation in practical cloud storage system. In this paper, we ﬁgure out the collusion attack in the exiting scheme and provide an efﬁcient public integrity auditing scheme with secure group user revocation based on vector commitment and veriﬁer-local revocation group signature.
