Differential Power-Analysis Attacks. Edition No. 1
VDM Publishing House, March 2008, Pages: 80
Implementations of theoretically secure cryptographic algorithms can be broken by side-channel
attacks. In particular, block ciphers have turned out to be very susceptible to
differential power-analysis (DPA) attacks. Various methods to prevent these attacks have
been proposed so far. This book is about countermeasures against DPA attacks, which
can be easily implemented in a standard CMOS design flow. In particular, the work focuses
on the insertion of dummy operations, on the randomization of operands and on the
generation of noise. The effectiveness and the costs of these countermeasures are analyzed.
In addition, an ASIC design implementing these countermeasures is presented. The design
is a strong authentication module using AES equipped with the countermeasures. First
measurement results of this design based on an FPGA prototype are also part of this book. Not only researchers in the area of cryptography and security are addressed by this work but also hardware security designers.
