In manufacturing organizations, the flow of information often is essential to the functioning of critical design, processes, machinery, or systems on which the company depends. Thus, Cyber security rather than being an option becomes a necessity as critical piece of every system in the organization. For many manufacturers, integrating plant floor data with enterprise systems poses sufficient challenges. It’s no wonder that one of the biggest reason manufacturers are hesitant to connect plant floor systems to the corporate network and extend Internet connectivity to production data is security. The data sharing is one of the concerning functionality in today’s world as it involves security, efficiency and flexibility as their important aspects. With the introduction of encryption and decryption schemes, the storing, sharing and securing of data became rampant. The storing of these cipher texts and the decryption keys is one of the major issues. There is a need for a mechanism which can minimize the cost of storing these cipher texts and keys in a secured way. Protecting user’s data privacy is one of the critical goals of cloud storage. This research effort focuses more on aggregation of these keys into a single aggregate key which will in turn reduce the burden on the network overhead
