Abstract
The camouflage technique described herein introduces programmed configuration inputs to Micro Netlists, creating Programmable Micro Netlists (PMNLs). PMNLs are a group of camouflaged and non-camouflaged cells that may be configured to perform one of several possible logic functions. They retain all the protective properties of non-programmable MNLs, but also allow for secure post-manufacture configuration of their aggregate logic function.
