Abstract
The design and analysis of lightweight block ciphers is gaining increasing popularity due to the general assumption that in the future extensive use will be made of block ciphers in ubiquitous devices. In this PhD thesis we address cryptanalysis of several lightweight block ciphers using algebraic and side channel attacks.
In the first part of the thesis, we investigate the security of the NOEKEON block cipher. We provide the first result of side channel attack on NOEKEON using side channel cube attack.
In the second part of this thesis, we improve the original cube attack by Dinur and Shamir in EUROCRYPT 2009 by introducing an efficient method called extended cube for extracting low-degree nonlinear equations. We apply our extended cube method on PRESENT-80 and PRESENT-128. We show that using our extended cube method, we have been able to improve the previous side channel cube attack on PRESENT-80 from CANS 2009. However our attack on PRESENT-128 was the first attack in the side channel model.
Finally, in the final part of this thesis we investigate the security of the three variants of the KATAN block cipher, namely, KATAN32, KATAN48 and KATAN64 against fault attacks.
