Microsoft Gazelle
Last week, Microsoft Research released an interesting paper about a web browser, Gazelle, which acts like an OS with the browser kernel specifically securing its resources and sharing across web sites.

The Idea behind Gazelle is to create a browser that is more secure for the current typical dynamic web pages that we find on web. Gazelle is different as no existing browsers, including new architectures, haveing a multi-principal operating system constructed providing the browser-based OS control, exclusively, to mange the protection of all system resources.

Gazelle's security model is centered around protected principals from one another by seperating their respective resources into hardware-isolated protection domains. Any sharing between two different principals must be explicit using cross-principal communication(or IPC) mediated by Browser Kernel.
