Data sharing in cloud computing permits multiple participants to freely share the cluster data that improves the potency of labor in cooperative environments and has widespread potential applications. However, how to make positive the protection data of data of knowledge sharing among and thus the due to expeditiously share the out sourced information in Associate in Nursing very cluster manner unit of measurement formidable challenges. Note that key agreement protocols have contend a very necessary role in secure and economical cluster data sharing in cloud computing. throughout this paper, by taking advantage of the Centro parallel balanced incomplete block vogue (SBIBD), we have a tendency to tend to gift a novel block design-based key agreement protocol that supports multiple participants, which may exile extend the amount of participants in Associate in Nursing very cloud surroundings the structure of the block vogue. Supported the planned cluster data sharing model, we've a bent to gift general formulas for generating the common conference key K for multiple participants. Note that by taking advantage of the block vogue, the method complexity of the planned protocol linearly will increase with the amount of participants and to boot the communication quality is greatly reduced. To boot, the fault tolerance property of our protocol permits the cluster data sharing in cloud computing to face to completely different key attacks, that is analogous to protocol.
