Up in the Air: Cloud Computing Security and RSA Algorithm

Cloud computing has been the pillar of technology in the past few years, with some rare exceptions of organizations or businesses that have not accepted and/or embraced its power. The scope of this paper includes issues in Cloud Security, including major domains such as Confidentiality, Privacy, Data Integrity, Identity Management and other common aspects. One such focus in this disquisition is one of the possible solutions aiming to strengthen security, viz. Encryption and Decryption, using the RSA Algorithm. After covering various security aspects and issues in the initial segments, using brief and concise explanations, the challenges due to network concept are covered in the subsequent section. Further, the survey covers the recent works and developments or modifications in the RSA algorithm, in other words, its evolution over the recent years. RSA is one of the oldest algorithms for encryption and decryption and consists of basic three steps, Key Generation, Encryption, and Decryption. This is explained in the last section, where the algorithm itself is also presented.
