Differential Fault Analysis on Lightweight Blockciphers with Statistical Cryptanalysis Techniques

Differential fault analysis is one of the most efficient side channel attack techniques that threat the security of block cipher. However, it often requires a penultimate or an antepenultimate round faulty encryption and is not suitable for middle round fault. This paper presents attacks combining differential fault analysis with statistical cryptanalysis techniques against lightweight ciphers. The analysis makes use of statistical cryptanalysis techniques in practice rather than theoretically, and exploits the weakness of bit-permutation adopted by many lightweight block ciphers under fault attack. Specific attacks against PRESENT and PRINTscriptsize{CIPHER} normalsize are given to prove the validity. The result shows that about one fifth of the iterative rounds are needed to be protected for these lightweight ciphers with bit-permutation.
