One of the major challenge in cloud computing is providing security for the data. The main aim of this project is to provide a security for data in cloud and also to propose a proper key management system using key sharing technique with multiple key managers. To avoid unauthorized access to cloud data, access control mechanism must be enforced. Moreover, data leakage and data privacy strategies must be employed so that only authorized users can access and utilize data. Encryption techniques provide a solution to ensure privacy and confidentiality of stored data. Key management becomes a prime issue in the case of encryption. Cryptographic keys need to be stored and protected. Compromise or failure of a key storage facility may lead to the loss of data. Another issue in security for cloud data is that there is a man-in-the-middle attack. The intruder may access the user files illegally due to improper authentication system. This can be overcome by using proper authentication between user and cloud. The security concerns of outsourcing data to public clouds, serves as a motivation to work for the development of data security technique. We aim for a technique capable of addressing the aforementioned critical issues. We proposed a data security scheme that uses key manager servers for the management of cryptographic keys.
