Enhancing the Security of Sensitive Data in Cloud Using Enhanced Cryptographic Scheme

Cloud computing is powerful evolving on-demand computer system resources technology, As the technologies are increasing day by day the problems associated with them would also increase. Cloud security is one of the major concerns in today. Cloud is useful for the storage of data and need not be managed by the direct users or owner of the data. Data are not be saved in the physical device of the user but in a third-party cloud storage. The major issue with cloud computing is the lack of trust on the security. The purpose of study is to enhance and ensure the security of sensitive data in cloud using enhanced encryption scheme. In this paper, cryptography is proposed as a method of protecting sensitive data by various tools and techniques. The cryptography algorithm used in the proposed methodology are AES, SAL, Blowfish and CSL algorithms and a through a comparative analysis the most effective and secured algorithm is suggested. In proposed methodology information transmitted with confidentially, without any breach or any alteration in data, information is transferred in secured way that only the authorized person is able to process or receive the data.
