A Survey of Hardware Trojan Taxonomy and Detection

10 Jun 2010 | Publications | Contributor(s): Mohammad Tehranipoor

Editor's note: Today's integrated circuits are vulnerable to hardware Trojans, which are malicious alterations to the circuit, either during design or fabrication. This article presents a classification of hardware Trojans and a survey of published techniques for Trojan detection. -Krish …

Hardware Trojan: Threats and Emerging Solutions

25 Aug 2010 | Publications | Contributor(s): Seetharam Narasimhan, Swarup Bhunia

Malicious modification of hardware during design or fabrication has emerged as a major security concern. Such tampering (also referred to as Hardware Trojan) causes an integrated circuit (IC) to have altered functional behavior, potentially with disastrous consequences in safety-critical …

Multiple-Parameter Side-Channel Analysis: A Non-Invasive Hardware Trojan Detection Approach

25 Aug 2010 | Publications | Contributor(s): Seetharam Narasimhan, Swarup Bhunia

Malicious alterations of integrated circuits during fabrication in untrusted foundries pose major concern in terms of their reliable and trusted field operation. It is extremely difficult to discover such alterations, also referred to as “hardware Trojans” using conventional structural or …

A LAYOUT-AWARE APPROACH FOR IMPROVING LOCALIZED SWITCHING TO DETECT HARDWARE TROJANS IN INTEGRATED CIRCUITS

26 Aug 2010 | Publications | Contributor(s): Hassan Salmani, Mohammad Tehranipoor

Malicious activities and alterations to integrated circuits have raised serious concerns to government agencies and the semiconductor industry. The added functionality, known as hardware Trojan, poses major detection and isolation challenges. In this paper, we present a method to localize design …

New Design Strategy for Improving Hardware Trojan Detection and Reducing Trojan Activation Time

28 Aug 2010 | Publications | Contributor(s): Hassan Salmani, Mohammad Tehranipoor

Hardware Trojans in integrated circuits and systems have become serious concern to fabless semiconductor industry and government agencies in recent years. Most of the previously proposed Trojan detection methods rely on Trojan activation to either observe a faulty output or measure …

Self-Referencing: A Scalable Side-Channel Approach for Hardware Trojan Detection

27 Aug 2010 | Publications | Contributor(s): Seetharam Narasimhan, Swarup Bhunia

Malicious modification of integrated circuits (ICs) in un- trusted foundry, referred to as "Hardware Trojan", has emerged as a serious security threat. While side-channel analysis has been reported as an effective approach to detect hardware Trojans, increasing process variations in nanoscale …

Hardware Trojan Detection and Isolation Using Current Integration and Localized Current Analysis

28 Aug 2010 | Publications | Contributor(s): Hassan Salmani, Mohammad Tehranipoor

This paper addresses a new threat to the security of integrated circuits (ICs). The migration of IC fabrication to untrusted foundries has made ICs vulnerable to malicious alterations, that could, under specific conditions, result infunctional changes and/or catastrophic failure of the system in …

Collaborative Trust: A Novel Paradigm of Trusted Mobile Computing

15 Oct 2010 | Publications | Contributor(s): Swarup Bhunia

With increasing complexity of modern-day mobile devices, security of these devices in presence of myriad attacks by an intelligent adversary is becoming a major issue. The vast majority of cell phones still remain unsecured from many existing and emerging security threats. To address the security …

Trustworthy Hardware: Identifying and Classifying Hardware Trojans

23 Oct 2010 | Publications | Contributor(s): Jeyavijayan Rajendran, Mohammad Tehranipoor

For reasons of economy, critical systems will inevitably depend on electronics made in untrusted factories. A proposed new hardware Trojan taxonomy provides a first step in better understanding existing and potential threats.
