Cloud computing is a revolution in the IT industry due to its characteristics of scalability, efficiency, and availability. Along with these benefits, cloud computing comes with certain security issues that a user has to take into consideration. Security of data and its integrity verification in the cloud are major issues that act as a barrier to the adoption of cloud computing. In the authors' previously published work, a one-way hash function was proposed to verify the data integrity at the cloud storage site. This article further extends prior work. In this article, the modified one-way hash algorithm is implemented by using a Hadoop distributed file system (HDFS) service of Hadoop environment and analytical testing is performed to ascertain its performance. Statistical and experimental results reveal the proposed algorithm is robust, which ensures data integrity and fulfills mostly all essential features of a secure hash function.

Flow Of Information

In Cloud computing environment QoS i.e. Quality-of-Service and cost is the key element that to be take care of. As, today in the era of big data, the data must be handled properly while satisfying the request. In such case, while handling request of large data or for scientific applications request, flow of information must be sustained. In this paper, a brief introduction of workflow scheduling is given and also a detailed survey of various scheduling algorithms is performed using various parameter.
