IC Protection from IP and IC Piracy using AES Logic Encryption

Most of the IC’s are implemented by means of IP piracy and IC piracy. Usage of hardware intellectual property by the third party is known as IP piracy and manufacturing the IC without the knowledge of IC owner is known as IC piracy. The objective of this paper is to avoid this IP piracy and IC piracy. Various methods to avoid this IP and IC piracy are exist in the literature such as logic obfuscation, logic encryption, split manufacturing, IC Camouflaging, and Trojan Activation. This paper deals with the logic encryption method to avoid the IP and IC piracy. Logic encryption is done by means of introducing the key gates where one of the input given to the key gates is called as key input. In our proposed paper, AES encrypted key is given to the key circuit.
