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.
