N. Hemalatha, A. Jenis, A. Cecil Donald, L. Arockiam . A Comparative Analysis of Encryption Techniques and Data Security Issues in Cloud Computing. International Journal of Computer Applications. 96, 16 ( June 2014), 1-6. DOI=10.5120/16875-6873
Cloud computing has been seen as the next generation architecture of IT enterprise. The cloud paradigm advantages and its potential for decreasing costs and reducing the time for a service that favours towards security issues. Cloud Computing is an aggregation of IT services that offered to the customer based on leasing. Though a large number of security issues are addressed, still some are not addressed and several algorithms are proposed for security issues. This paper presents a perspective of cloud computing technologies, essential characteristics, classifications, delivery models and various encryption mechanisms. A comparative study made on several encryption techniques are used for maintaining the confidentiality in the cloud. Finally, the major data security issues present in cloud computing are discussed.
