Normalized Inter-class Variance (NICV)

Abstract

The internet of things leads to a massive interest in security of embedded devices. Nowadays, power analysis poses extremely effective and successful types of attacks to break confidential cryptographic algorithms such as AES (Advanced Encryption Standard), RSA (Rivest Shamir Adleman) and cryptographic devices such as smart cards. This paper deals with the method of localization of interesting markers in power analysis called NICV (Normalized Inter-Class Variance). The aim of the paper is to describe this method and its implementation.
