Cloud Computing technology offers new opportunities for outsourcing data, and outsourcing computation to individuals, start-up businesses, and corporations in health care. Although cloud computing paradigm provides interesting, and cost effective opportunities to the users, it is not mature, and using the cloud introduces new obstacles to users. For instance, vendor lock-in issue that causes a healthcare system rely on a cloud vendor infrastructure, and it does not allow the system to easily transit from one vendor to another. Cloud data privacy is another issue and data privacy could be violated...

Data sharing in cloud computing enables multiple participants to freely share the group data, which improves the efficiency of work in cooperative environments and has widespread potential applications. However, how to ensure the security of data sharing within a group and how to efficiently share the outsourced data in a group manner are formidable challenges. Note that key agreement protocols have played a very important role in secure and efficient group data sharing in cloud computing. In this paper, by taking advantage of the symmetric balanced incomplete block design (SBIBD),...

There is a perfect storm of the use of cloud computing, and the growth of Internet of Things (IoT). IoT is about processing data that comes from devices in some way that's meaningful, and cloud computing is about leveraging data from centralized computing and storage. Growth rates of both can easily become unmanageable. We have some problems to solve. In addition, alternatives are being consider to placing everything in the public cloud because the public cloud, in some cases, no longer makes sense....
