Emerging Hardware Trojan Threat to Integrated Circuits -Remedies to Protect the Integrated Circuit

Due to growing of semiconductor industry and the increasing demand in fabricating digital integrated circuit, are now facing problem with a hardware threat which is known as hardware Trojan horse. Hardware Trojan (HT) results in harmful, unauthenticated modification to integrated circuit (IC), which is a major part of electronics. The modification may leak important information ,causing the system to fail while operating in real time. HT has been found as a problem to military, medical, transportation and other critical systems. It is a major security threat for the integrated circuits like FPGA, ASIC, Microcontroller, microprocessor .Hence it is a major security challenge to prevent and detect the hardware Trojan. In this regard first one have to know the ways in which this HT can be encountered. The most significant way to handle this Trojan problem is to understand the Trojan classification and counter attack techniques. A new taxonomy was presented in this paper to handle the HT, this classification covers the prevention and detection methods.
