Abstract: Provided are methods, systems, devices of a security-driven design method. The present methods and systems can enable integration of security requirements in the early stages of design along with other design constrains so that potential attacks during IC development, usage, and retirement would render ineffectual. Example methods and systems can comprise circuits and circuit design using vanishable logic through a novel hybrid design method. An example method or system can comprise vanishable logic based on hardware re-configuration and transformation by employing non-volatile memory cells.
