Abstract: In today?s technology drive world cloud computing provides remote services using internet. Hence most of the people are going towards public cloud for secure data storage as well as sharing. With these several advantages, there are many issues associated with storage & sharing of data in public cloud. The user should able to transfer and control the remote data which is still lacking in today?s public cloud infrastructures. Other problems are related to privacy, security, integrity, privilege management, confidentiality etc. So the solution to all these is to encrypt the keys along with the data and then the grant the permission to access the data, which can be revoked at any time. Also it is possible to update the group key pair even though not all the members of group online. In this paper we analyzed different methods and parameters used for secure group communication.
