Securing VLSI Circuits against Side Channel Attacks by using Efficient Detection Technique

Abstract

This research investigates important class of hardware attacks against various embedded devices newlinewhich uses side channel attacks ( passive attacks) and fault injection attacks(active attacks) as a newlinehacking tool. Adversary cleverly chooses these attacks methods in order to break the security of newlineembedded devices. newlineIn case of fault injection attack methods, faults are injected into devices and their faulty behavior newlineare exploited to retrieve secret information. Attacker then observes the faulty behavior in order to newlineextract the secret key. Critical analysis of the properties and the components engaged with these newlinefault injection methods is of high importance to assess the related dangers and furthermore to newlineenhance the process of designing suitable counter-measures. Designing efficient newlinecountermeasures requires first understanding the fault injection attacking process in detail. This newlinerequires thinking and understanding from attackers view point. In contrast to active attacks, newlinepassive attacks are performed by just observing the information consumed during computation of newlineany cryptographic operation such as timing information, power consumption of device etc. Both newlinetypes of attacks are equally important to understand so as to design embedded system resistant newlineagainst all types of attacks. newline newline
