Advances in the Side-Channel Analysis of Symmetric Cryptography
Side-Channel Analysis (SCA) is an implementation attack where an adversary exploits unintentional outputs of a cryptographic module to reveal secret information. Unintentional outputs, also called side-channel outputs, include power consumption, electromagnetic radiation, execution time, photonic …

Architecture Support for Countermeasures against Side-Channel Analysis and Fault Attack
… designed to be mathematically secure; however, side-channel analysis attacks go beyond mathematics by taking measurements of the device’s electrical activity to reveal the secret data of a cipher. These attacks also go hand in hand with fault analysis techniques to disclose the secret key used …

A Deep Learning Approach to Side-Channel Analysis of Cryptographic Hardware
… adversaries, a class of physical attacks called side-channel analysis (SCA) has emerged which compromises the security of systems. While security claims of cryptographic algorithms are based on the complexity of classical cryptanalysis attacks, they exclude information leakage by implementations …

Partition based Approaches for the Isolation and Detection of Embedded Trojans in ICs
… has been manufactured. This obviates the use of side-channel signal(s) that acts like a signature of the IC as a means to assess its internal behavior under operational conditions. In this work, we have selected power as the side-channel signal to characterize the internal behavior of the ICs. We …
