Group Management for Secure and Dynamic Sharing of Data in Cloud Computing
Resumé
Cloud computing has emerged as new model of computing which allows outsourcing data. The phenomenon of outsourcing data to cloud became obvious as cloud has infrastructure as a service (IaaS) layer for it. With this feature of cloud, there is growing trend in outsourcing data to cloud. When an enterprise outsources its data to cloud, it needs to take care of its functionalities in terms of data sharing across its users. The company creates groups and manages group members in order to have secure and dynamic data sharing. Group manager is responsible to determine data to be shared and privileges of group members. Group management is very dynamic thing where new users may be added and existing members may be removed from group. The users who are not associated with the group may involve in collusion attack. The existing systems focus on group management and data sharing. In this paper, we built a mechanism for revoking a user and disable all credentials given to him. We built a prototype application that demonstrates the proof of concept. The empirical results revealed that the proposed scheme is effective. Keywords: Cloud computing, outsourcing, group management, secure data sharing, user revocation Cite this Article Raju Dara, Bhongir Sony.
