Abstract

Optical Fiber Sensor Based on Second-Order Superstructure Fiber Bragg Grating

Highlights

  • Hardware-level physical security has been highly required, as secure data exchange via various communication networks and devices, such as a wireless sensor network, is increased.[1,2] Physical attacks are threats to the integrated circuits (ICs) implemented in electronic devices containing the secure information of the user, such as smartcards and smartphones

  • Fault injection attacks are highly dangerous because of their effectiveness and low cost. They are a threat to data security as they can extract the secure information stored in the target device

  • Fault injection attacks can be made to occur by several approaches such as clock glitching, voltage glitching, overclocking, electromagnetic (EM) pulses, and temperature.[3]. A temperature fault injection attack changes the environment temperature of the attacked chip, causing it to operate outside of the allowed operating temperature range, and extracts the secure information stored

Summary

Introduction

Hardware-level physical security has been highly required, as secure data exchange via various communication networks and devices, such as a wireless sensor network, is increased.[1,2] Physical attacks are threats to the integrated circuits (ICs) implemented in electronic devices containing the secure information of the user, such as smartcards and smartphones They can be classified into two categories: invasive and noninvasive attacks. Fault injection attacks are highly dangerous because of their effectiveness and low cost They are a threat to data security as they can extract the secure information stored in the target device. A secure circuit with a low-power on-chip temperature sensor is presented for the detection of temperature fault injection attacks. The XOR gate is implemented to detect and shut down the protected circuit when the temperature is below −10 °C or above 80 °C by using the two comparator output signals
