Design and Implementation New Techniques to Prevent Trojan Thread in Parallel CORDIC

Trojan thread affects the Integrated Circuit (IC) and changes its operation. Trojan thread is injected to the designs that have no security or weak security. After inserting Trojan thread, the IC operates in different behavior other than the intended behavior. The aim of the Trojan thread is to defect the IC operation or leak information from the IC to another IC through established link wired or wireless to the attacker. The presence of Trojan thread in IC lead to high losses and increase the defective products. There for it is very important to decrease the effect of the Trojan thread. In this paper we insert Trojan thread inside Coordinate Rotation Digital Computer (CORDIC) and see its effect and represent techniques to increase the design immunity against the Trojan thread.
