ABSTRACT
Over the last few years industry is facing problems against new kind of attacks known as hardware attacks / physical attacks / side channel attacks. Engineers faces a challenge for building resistant free embedded system against attacks called as side channel attacks. Leaking information from computer devices (such as voltage fluctuations, power consumption, etc.) rather than software algorithms come under the category of hardware attacks or side channel attacks. Countless embedded devices are becoming victim to side channel attacks every day, and malicious attackers have become smart enough to impose threats on them. Therefore, there is a strong need to address issues related to side channel attacks. This chapter will provide an insight into the field of hardware security; it will provide a deep investigation of various types of side channel attacks and better understanding of various power analysis tools and fault injection techniques, which will further give researchers a vision to build efficient and secure systems in order to thwart attacks. This chapter focuses both on passive attacks as well as active attacks since embedded systems needs security against all kinds of attacks.
