This book consolidates several key aspects from the state-of-the-art
research in symmetric key cryptography, which is among the cornerstones
of digital security. It presents the content in an informative yet
beginner-friendly, accompanied with toy examples and comprehensible
graphics. In particular, it highlights the recent developments in
tool-assisted analysis of ciphers. Furthermore, promising
device-dependent attacks, such as fault attack and side channel attacks
on symmetric key ciphers, are discussed in detail. One salient feature
of this book is to present a detailed analysis of various fault
countermeasures. The coverage of our book is quite diverse--it ranges
from prerequisite information, latest research contribution as well as
future research directions. It caters to students and researchers
working in the field of cryptography.
