Side channel attacks and their mitigation techniques

Side channel cryptanalysis is one of the most volatile fields of research in security prospects. It has proved that cryptanalysis is no more confined to its dependence on plain text or cipher text. Indeed side channel attack uses the physical characteristics of the cryptographic device to find the cryptographic algorithm used and also the secret key. It is one of the most efficient techniques and has successfully broken almost all the cryptographic algorithms today. In this paper we aim to present a review on the various side channel attacks possible. Also, the techniques proposed to mitigate such an attack have been stated.
