An Efficient Approach to Enhance Data Security in Cloud Using Recursive Blowfish Algorithm

Abstract

Cloud computing and Services have gained popularity both from industry and academia since both enable the rapid development of the distributed computing in areas of collaborative research and development, healthcare, grid-enabled applications, enterprise computing infrastructure, military applications and domestic Security. The existence of the Service providing system depends on the customer's requirements. Software Engineering is one of the disciples which orients towards accomplishment of quality in technology thorough best principles and practices. Applying these software engineering quality attributes enables one to achieve customer satisfaction in cloud applications. Security which is one of the significant quality attributes is also deemed to be one of the biggest issues in cloud computing since it needs to be managed and control huge amount of data. Cryptography is one of the popular methods of achieving data security, whose objective is to covert information from original form into unreadable form. Despite of advancement in technology and existence of various security models for realizing secured encryption process, there still prevail various security issues during data transfer. The objective of this paper is to enhance the Customers satisfaction by providing an improved level of security through reduced possibility for hacking through Blowfish algorithm by varying the number of rounds and decide the value of N, which is complex and confuses the hacker.
