Abstract: Cloud Computing is playing the significant role in the existent submissions the humans life. Cloud computing is an extravagant set of conveniently and operative virtualized assets, like as hardware, evolution platforms and utility. Cloud computing is a exclusive generation of the parallel conception. The cloud computing extensibility is a concern of the allotment of revenue on mastery demand. Cloud computing accommodate the operation of uniting. The elevation of the cloud automation also raises the security controversy twice. So, there is a need to solve the security contention in the cloud automation. Reasons for maturity of cloud security for disparate inhabitants and disparate prospect depend upon the exaction. The main trouble correlate with cloud computing is data confidentiality, preservation, data stealing, data breaches etc. In this research work, it is proposed to use a new level of data security solution using Playfair cipher and Ceasar cipher algorithm. Both the algorithms are encrypted by the full set of 256 ASCII characters. A new encryption algorithm for security is implemented in this work. The main aim of this research work is to clarify the security issues in both cloud providers and cloud consumers using cryptography encryption methods. Index
