Design and Implementation of Authentication as a Service (Aaas) in Windows Azure Cloud Platform

Cloud computing is an internet based computing. It consists of various services and delievers on demand basis from the user request. Data security is a necessary facet for any web applications. Authentication is an important security problem in cloud as well as internet facing applications. This paper proposes authentication algorithms for securing the cloud applications. Authentication is an essential factor among other security parameters such as authorization, auditing and availability. These proposed algorithms are used to protect the unauthorized access in cloud. User's data are converted into different form using the different encryption techniques. These three algorithms are combined and provide as a single service to the cloud user. Proposed User authentication mechanisms are designed and developed in ASP.NET platform and deployed on Windows Azure platform of cloud System. This user authentication mechanism is simply matched with any kind of service within the cloud environment. The proposed user authentication algorithms have provided best security in cloud system. This mechanism can be used for agriculture, medical, education and IT based applications to firmly access the information in secured manner.
