The Implementation and Analysis of a Trojan Circuit in IC Chips

Hidden Trojan circuits provide an attacker with a stealthy attack vector.Trojan circuits can bypass traditional defensive techniques as they occupy a layer below the entire software stack.We present the design and implementation of a counter Trojan circuits into a IC chip by standard CMOS technology HJ0.25um,then we analyze such flexible hardware allows powerful,general purpose attacks,while remaining surprisingly low in the amount of additional hardware.
