Welcome to the Ring Cycle research project home page

The Ring Cycle is a currently active research project at the University of Illinois at Champaign-Urbana department of Electrical and Computer Engineering to improve operating system reliability and stability through driver isolation by using x86 protection rings and segmentation.

Please view the pages below for more detailed information on the protection model and implementation details. You may also browse the source code through the Browse Source link.
