ENHANCED INTEGRITY AUDITING FOR DYNAMIC AND SECURE GROUP SHARING IN PUBLIC CLOUD

The challenge faced in public cloud computing is to provide privacy and security to the data shared among the group members. In this paper, an enhanced secure group sharing framework has been proposed. As the cloud has a semi-trust relationship it is in need of a security model so that no classified information is being presented to cloud suppliers and aggressors. Another critical variable in giving protection and security is a periodical evacuation of undesirable records which if not done consistently then, might turn into a piece of enthusiasm for assailants and can be abused. By applying the proxy signature procedure, the grouping pioneer can adequately concede the benefit of grouping administration to one or more grouped individuals. The improved TGDH plan empowers the groups to arrange and overhaul the group key sets with the assistance of cloud servers, which does not require the greater part of the group individuals been online constantly. By receiving proxy re-encryption, most computationally escalated operations can be assigned to cloud servers without revealing any private data. An extensive study on security and its performance execution demonstrates that our proposed plan is exceptionally productive and fulfills the security necessities for public cloud based secure group sharing.
