Differential Power Analysis attack of CLEFIA Block cipher.
Masters thesis, Indian Institute of Technology Hyderabad.
Abstract
The objective of this research work is to mount Side channel attack particularly power analysis attack on FPGA Hardware implementation of CLEFIA block cipher. CLEFIA is claimed to be reliable cipher. CLEFIA specifications and design of algorithm is available to evaluation by public, cryptographers for performance and security analysis. CLEFIA is an international standardized cipher in ISO/IEC lightweight cryptography. It has four branch generalized Feistel network structure. This structure can be implemented compactly in both in hardware and software. CLEFIA consists of Diffusion Switching Mechanism, which ensures immunity against major attacks. Moreover, the similarity of functions between the data processing part and the key scheduling part of CLEFIA reduces the gate size.
