OpenID, a Single Sign-On Solution for E-learning Applications

The e-learning applications of today require a special focus on security. Distributed e- learning applications have several modules user can access using different clients (desktop or mobile). The same user has several accounts with different credentials. In this context, the SSO (Single Sign-On) solutions become very attractive since the user has to log in once and can access all the needed resources without being prompted again for the username and password. Using the OpenID standard for e-learning Web-based applications is a good and reliable solution because it supports both URL and XRI identifiers. This paper presents the main characteristics of OpenID standard and how this standard could be implemented for a distributed, Web-based, e-learning application.
