Abstract:Data integrity verification mechanisms play an important role in cloud environments. Recently, a lightweight identity-based cloud storage audit scheme has been proposed; this paper points out security vulnerabilities of their OffTagGen algorithm. That is, the attackers such as malicious cloud servers can forge the tags, which can destroy data integrity. By improving the construction of OffTagGen algorithm, an improved security cloud auditing protocol is proposed in this work to better protect user’s privacy. T… Show more
