Abstract:
An active shielding method is hereby introduced, providing security to security critical integrated circuits against some physical attacks such as probing, manipulation and modification. Active shields satisfy a physical clearance by preventing the reachability of the circuitry while they, themselves, are subject to modification in most cases. The proposed active shield, which is also subject to a patent application, provides the ability to detect any physical modification made on the shield itself by utilizing electrically configurable interconnections between shielding metal lines. By changing the selected interconnection configuration of the shielding lines, the proposed active shield provides a self detection ability as a countermeasure against the vulnerability to physical modification made on the active shield itself.
