Abstract : With the increase in the use of Integrated Circuits (ICs), fabrication takes place at different parts of the globe. The main aim of the Trojan attacks is to manually or automatically access the main core or node to get sensitive data or information for either personal benefits or for community benefit. This has increased the need to introduce hardware security module to protect the ICs from attacks like malware attack, password attack, phishing etc. These attacks help in either fetching the required data segments or exactly manipulating the architecture of the macros used in the core. This manipulation is called reverse engineering. This type of attacks is prevented by including hardware security modules to either core or to the necessary nodes where transition probability is high such that tapping of data through that node becomes difficult. Few types of hardware attack prevention techniques are encryption, hardware obfuscation, logic locking and IC camouflaging. In this work, hardware obfuscation is used to enhance the security of ICs. This prevention method is based on nodal insertion or insertion to the main core of the architecture. This is based on the application of the architecture of the core in the IC.
