Abstract
Cloud Computing has become one of the most talked about technologies in recent times and has got lots of attention from media as well as analysts because it is offering lots of opportunities. Enterprises have been determined to reduce computing costs and for that reason most of them started using it in IT technology then adapted virtualization technology. Cloud computing has revolutionized the way computing and software services are delivered to the clients on demand. It offers users the ability to connect to computing resources and access IT managed services with a previously unknown level of ease. Thus, security concerns among users of the cloud have become a major barrier to the widespread growth of cloud computing. In this research work, we have used the 3 step security mechanism for the keeping the data secure at the cloud. We have implemented the strong authentication mechanism using md5 encrypted OTP and enhanced the security of data using Cloud Broker and RSA, Blowfish and AES. When you log on to your machine and then try to access a resource, say a file server or database, something needs to assure that your username and password are valid. With sensitive data stored in the cloud of the different users, we need a strong authentication mechanism along with OTP. Data breaches because of no/weak authentication. Afterwards we have verified the integrity of data stored at cloud provider using SHA2. Multiple parameters like processing time, processing cost, AES,RSA and blowfish encryption time, OTP generation and encryption time have been calculated and analyzed. We have been able to enhance the security by optimizing the processing time as well as processing cost. After implementing the proposed methodology, it has been summarized that the cloud security can be enhanced by applying the proposed mechanism. The proposed system has reduced the complexity, processing cost which increases the overall efficiency of the system.

Summary
Cloud Computing has become one of the most talked about technologies in recent times and has got lots of attention from media as well as analysts because it is offering lots of opportunities. Cloud Computing is a term used to describe both a platform and type of application As a platform it supplies, configures and reconfigures servers, while the servers can be virtual machine or physical machine. Cloud Computing infrastructure allows enterprises to achieve more efficient use of their IT hardware and software investments. This is achieved by breaking down the physical barrier inherent in isolated systems, automating the management of the group of the systems as a single entity. Cloud Computing can be termed as virtualized system and a natural evolution for data centers which offer automated systems management. The consumer is responsible for the operating system and the entire software stack necessary to run applications, plus the data placed into the cloud computing environment. For SaaS, the infrastructure, software and data are primarily the responsibility of the provider, since the consumer has little control over any of these features of the service
