Abstract: The present disclosure presents various systems and methods for implementing a physical unclonable function device. One such method comprises providing an integrated circuit having a plurality of set/reset flip flop logic circuits, wherein each of the set/reset flip flop logic circuits enters a metastable state for a particular input sequence. The method includes varying circuit parameters for each of the plurality of set/reset flip flop logic circuits to account for manufacturing variations in the set/reset flip flop logic circuits and enable generating a stable but random output in response to the particular input sequence. Thus, by applying the particular input sequence to the integrated circuit, a unique identifier for the integrated circuit can be derived from an output response of the plurality of set/reset flip flop logic circuits.

Abstract: A system and method of protecting against control-flow attacks provides two complementary, transparent, and strong security policies for the RTL design at a hardware level. The approach performs static analysis of controller, followed by lightweight instrumentation, such that CFI is enforced in-place and at runtime. The modified controller follows conservative CFG with the help of a monitor.

Abstract: A method for reducing circuit sensitivity to single event upsets in programmable logic devices, involves identifying single event upset sensitive gates within a single event upset sensitive sub-circuit of a programmable logic device as determined by the input environment and introducing triple modular redundancy and voter circuits for each single event upset sensitive sub-circuit so identified.
