Performance Evaluation of Cloud Database Security Algorithms

Cloud computing is a group of servers providing the on demand computing services to the users on rental basis. One of the services providing by the cloud is Data Storage as a Service. In Data Storage as a Service user will outsource their sensitive data to cloud storage environment, where the users data will be stored and whenever user needs data, they will access from the cloud storage from anywhere and anytime using any device connected to the internet. One of the critical issues in this is data security. When user outsources their sensitive data to cloud vendor, the cloud vendor may leak the user’s sensitive data to third persons because vendor is not a trusted party. To overcome these problems there are many authors suggested different security algorithms. In this research we studied and evaluating the performances of those security algorithms and proposing a better solution, which provides best security to data stored in cloud databases.
