Abstract

The emerging security threats in the IC supply chain do not only challenge chip integrity, but also raise serious concerns on hardware Intellectual Property (IP) piracy. Existing register-transfer level hardware obfuscation methods for 2D integrated circuits (ICs) insert a key sequence in the control and data flow to prevent attackers from accessing the normal operation mode of a chip, rather than protecting state transitions in the normal operation mode. We propose a low-cost state-deflection based obfuscation method, in which we utilize a state rotation function and selective register flipping function to dynamically control the state deflection paths. As a result, we significantly increase the difficulty of reverse engineering and thwart register attacks on 2D ICs.

 

Three-dimensional (3D) integration has attracted significant attention during the past two decades to develop diverse computing platforms. Despite the well-understood advantages over 2D integrated circuits (ICs), 3D ICs introduce unique and unexplored challenges on managing hardware security. We propose a novel 3D obfuscation method to block the direct communication between two commercial dies in a 3D structure, thus thwarting reverse engineering attacks on the vertical dimension. We further propose a novel method for transistor level logic locking to address IP piracy and reverse engineering attacks in monolithic three-dimensional (M3D) ICs. The proposed method locks logic gates by independently inserting parallel or serial locking transistors and camouflaged contacts in multiple tiers in M3D ICs. Without the correct key bits and confidential information for camouflaged contacts, the locked logic gates will malfunction and significantly alter power profiles, which makes reverse engineering attacks more difficult.

Abstract

This talk presents two advanced visible light communication (VLC)modulator system-on-chips (SoCs). The first is an IEEE 802.15.7 PHY-I standard compliant VLC transmitter. The second is an active

matrix LED microdisplay with embedded VLC function. Using ordinary LED lights for VLC has received a great deal of research interest over the past decade due to a number of novel applications including

location-based wireless broadcasting through LED lightings, signs with LED backlights and digital LED displays. Most of the VLC SoCs development has focused on wireless optical receiver design including custom CMOS imager whereas VLC transmitters have been predominately based on discrete implementation until recently. More importantly, the power consumption of dedicated VLC transmitters is prohibitively high with bit efficiency in the 100 nJ/bit range. To overcome these issues, this work demonstrates the first fully integrated VLC transmitter SoC compliant with the IEEE 802.15.7 standard embedded with a built-in 8-W LED driver. Excluding the power consumed by the LED driver, the SoC

achieves a record VLC transmission efficiency of 5nJ/bit. On the other hand, the miniaturization and integration of inorganic LED display modules have attracted significant research efforts due to their superior brightness and reliability compared to organic LED microdisplay. Combining these two technology trends, this paper also describes an active matrix LED (AMLED) driver SoC with built-in VLC modulation capability to demonstrate a WQVGA smart microdisplay featuring 1.25-Mb/s VLC for enabling LED

digital signage as location-based information broadcaster and indoor positioning beacons.
