PROJECT TITLE:

Public Integrity Auditing for Shared Dynamic Cloud Data with Group User Revocation - 2015

ABSTRACT:

The advent of the cloud computing makes storage outsourcing become a rising trend, that promotes the secure remote information auditing a hot topic that appeared within the analysis literature. Recently some research take into account the problemof secure and efficient public information integrity auditing for shared dynamic data. However, these schemes are still not secure against the collusion of cloud storage server and revoked cluster users throughout user revocation in practical cloud storage system. In this paper, we have a tendency to figure out the collusion attack in the exiting theme and provide an economical public integrity auditing theme with secure cluster user revocation based on vector commitment and verifier-local revocation group signature. We have a tendency to style a concrete scheme based mostly on the our scheme definition. Our theme supports the general public checking and efficient user revocation and also some nice properties, like confidently, potency, countability and traceability of secure group user revocation. Finally, the protection and experimental analysis show that, compared with its relevant schemes our theme is also secure and efficient.
