A Secure Single Sign ? On Scheme for Distributed Systems and Network

Single Sign On (S SO) has been around for many years to provide a single authentication for rendering multiple services. For instance Google has been using its S SO approach to render various services in a distributed computing environment. This will enable legal users to have a single credential for accessing all services provided by an enterprise through its web application on line. This will help end users to have advantages such as remembering only one login credentials for all activities. Chang and Lees S SO scheme was improved recently by Wang et AL. to overcome the drawbacks of the work of Chang and Lee. The credential hacking by malicious service provider and outsider hacking credentials are the two problems overcome in their research. Inspired by this, in this paper we attempted to build a prototype application that demonstrates the concept of S SO. The application has many services and multiple users with effective session management. The empirical results reveal that the prototype is able to provide secure S SO.
