With the use of cloud computing, users can develop a growing and balanced way for data exchange between groups and individuals, with the characteristics of less management and little maintenance expense. Because the security of outsourced data is uncertain, it offers a security certification for data exchange. Due to the group's memberships often changing, privacy protection becomes a problem, especially for untrusted clouds as a result of collusion or pilot attacks. Key distribution in the current system is based on secure communication channels. Everyone is aware of the key, and using it effectively is exceedingly challenging. In this research, we propose a secure way for users to learn their private key from their group manager without the need of any communication channels. Data encryption and decryption methods use the AES algorithm, while key distribution among the group members via ring signature.
