Extensive medical data storage with prominent symmetric algorithms on cloud - A protected framework

The cloud is an emerging field in the IT. It is a way of delivering IT-enabled services in the form of software, platform and infrastructure. Cloud computing in recent times has become a trend among all walks of life to store and retrieve data from anywhere around the globe. With the rising cost for the data storage devices and data retrieval process; enterprises have moved to centralized storage for cost efficiency. This proves a greater task to the service providers in terms of security and consistency. As shared systems are prone to be attacked, various counter measures have been proposed by experts to secure the stored data. Here the data is being encrypted by the advanced encryption algorithm which is considered to be the most competent in the present security scenario. A symmetric key is generated to the stored file. To further enhance the trust of the service provider the trust certificate of the company is being sent along with the keys to the client. All the communication process is taken place using the Key Exchange protocol. These techniques are performed to ensure the client that the stored data is being secured, integrated and a total control over the route in which the data is being communicated. In this paper, a new efficient technique is proposed which indicates the effectiveness, flexibility of the storage and retrieval process by a generic framework. This framework fills the gap between the security needs and challenges.
