Cloud computing is an emerging and advanced technology in IT enterprise which provides services on demand. Cloud computing includes many advantages such as flexibility, improved performance and low cost. Besides its advantages, cloud has many security issues and challenges. In this paper, we propose an enhanced frame work for data security in cloud which follows the security polices such as integrity, confidentiality and availability. The data is stored in cloud by using 128 bit encryption and RSA algorithm, then we use the trust management i.e., Trusted Party Auditor (TPA) which audits the data instead of client. Thus, we show how efficiently the data can be secured related to performance analysis. © 2014 IEEE.
