The sharing of data in cloud computing allows multiple participants to freely share group data, improving efficiency and broad potential applications in co-operative environments. Nonetheless, it is daunting challenges how to ensure the security of data sharing in a company and how to transfer outsourced knowledge effectively. Note that key agreement protocols have played a very important role in secure and efficient group data sharing in cloud computing. Block Design-based Key Agreement for Group Data Sharing in Cloud Computing. In this article, a new block design cantered main arrangement, which assisted multiple participants, by using the symmetrical balanced incomplete block design (SBIBD), which allows the number of participants in the cloud environment to be expanded in a flexible way according to the block design structure. General formulas for creating a popular conference core K for several participants cantered on the suggested community data sharing model. It should be remembered that the computational complexity of the proposed protocol rises linearly with the participation rate (v; k+ 1; 1)-block size and greatly reduces coordination difficulty. In order to avoid different key assaults, which is identical to Yi Protocol, the fault tolerance feature of our protocol allows Team data sharing in cloud computing.
