Information-flow-based access control for web browsers

Download paper


The emergence of Web 2.0 technologies such as Ajax and Mashup has revealed the weakness of the same-origin policy [1], the current de facto standard for the Web browser security model. We propose a new browser security model to allow fine-grained access control in the clientside Web applications for secure mashup and user-generated contents. We propose a browser security model that is based on information-flow-based access control (IBAC) to overcome the dynamic nature of the client-side Web applications and to accurately determine the privilege of scripts in the event-driven programming model.
