SAT attack directly finds the key used for obfuscation.

1. The features of design integrated with gate camouflaging can never be reverse engineered.

2. The entire truth table is not needed to attack a design obfuscated by camouflaging.

3. In state space obfuscation, modification cells are added to hide the newly inserted FSM.

4. An attacker cannot reverse engineer the FPGA netlist from the obfuscated bitstream.

5. FPGA-mapped designs are efficiently mapped, keeping almost no unused space in look-up-table memory cells.
