Classification overview of the Hardware Trojans in digital circuits

Abstract

This paper presents an overview of the Hardware Trojans classification methods. A malicious entity can introduce a Hardware Trojan (HT) into a design in order to denial of service, destroy or disable the system. Moreover, it could leak the confidential information and the secret keys before altered them. The Hardware Trojan (HT) threats should be analyzed with maximum importance through the entire lifecycle of the integrated circuit (ICs). A hardware protection against the detected harmful logic should also be implemented.
