Efficient and Secure Cloud Data Distribution and Sharing Scheme in Groups

As we know in today's era, people are keen in exchanging the data online with the other members in the cloud via data storage and retrieval. However Storage and retrieval of data are one of the key issues encountered in Cloud Computing domain. Here in my research, the data will be stored in cloud in groups. With untrusted cloud also being taken into the account, several algorithms like Group Signature verification and strong encryption-decryption techniques will be used to secretly share the data with other users. It introduces a trusted third party as a Data Center to activate and deactivate a new user and to reveal the real identity of the user in case of any disputes and also Private Key Generator (PKG) that will responsible in generating the private keys that will be used by the members and Data Center.
