Abstract: The cloud computing provides convenient ondemand access of the data. Sharing of data in the cloud computing will enable several users to easily handle the data that is being shared. The medical-field finds more advantages by the cloud-computing technology as the data can be accessed anywhere and anytime by the patients as well as this data can be shared with other medical-practitioners. This alarms for the security issues as the huge amount of sensitive data is being shared. The data must not be available to malicious-attackers. In this paper, we propose the block-design based key agreement protocol in order to share the data securely and the design provides fault-detection and fault-tolerance. The group-data model PSM is given with the block-based design, which decides how the sharing of the data is done by grouping and giving positions to users in particular blocks and the column. The design is proposed in our paper, which gives the technique for positioning of the users. The encryption and decryption of data is done and their times cost according to file size is found. The comparison of the time-cost for our model and existing models is compared with respect to different number of simulations.
