Abstract

Data sharing in cloud computing permits multiple participants to freely share the group information thathelps in improving the efficiency of work in cooperative environments and has widespread potential applications.However, ensuring the security of information sharing within a group and outsourcing the group information efficiently is an alarming challenge. Note that key agreement protocols like RSA plays a crucial rolein securing group information sharing in cloud computing. In this paper, by taking the advantage of key agreement algorithms and by setting the threshold percentage of key for accessing the data we are designing a secure and efficient group information sharing system. By using auditing the malicious user is also detected by the system. In addition, the fault tolerance property of our system enables the group information sharing in cloud computing to withstand key attacks like giving wrong key by the group member.
