Patent number: 8584224Abstract: A system for authenticating a user to a relying party. A user sends an access request to a relying party web application. In response, the application sends a page with JavaScript that detects a plug-in at the user and detects the relying party domain. The plug-in uses its device certificate or other pre-established credentials to sign a challenge along with other site and user information including the site domain, the authentication service URL and user identifier, and send it, along with the data including the domain and the user identifier, to an authentication service. The service authenticates the information and sends back to the plug-in a short ticket that can be passed on to the relying party, which can validate it using the Radius protocol and an authentication service call, thereby authenticating the user.Type: GrantFiled: April 13, 2011Date of Patent: November 12, 2013Assignee: Symantec CorporationInventors: Mingliang Pei, Jeff Burstein, Liyu Yi, Rosarin Jolly Antonyraj, Rong Cao
