GIFT, a lightweight block cipher proposed at CHES2017, has been widely cryptanalyzed this years. This paper studies the differential diffusion characteristics of round function GIFT first, and proposes random nibble-based fault attack. The key recovery scheme is developed on statistical properties we found for distribution table S-box. A lot experiments had done experimental results show that o...

In this paper, we propose a new method of differential fault analysis of SHA-3 which is based on the differential relations of the algorithm. Employing those differential relations in the fault analysis of SHA-3 gives new features to the proposed attacks, e.g., the high probability of fault detection and the possibility of re-checking initial faults and the possibility to recover internal state...

Differential and linear attacks are the most widely used cryptanalytic tools to evaluate the security of symmetric-key cryptography. Since the introduction of differential and linear attacks in the early 1990’s, various variants of these attacks have been proposed such as the truncated differential attack, the impossible differential attack, the square attack, the boomerang attack, the rectangl...

In this paper, we present a related key truncated differential attack on 27 rounds of XTEA which is the best known attack so far. With an expected success rate of 96.9%, we can attack 27 rounds of XTEA using 2 chosen plaintexts and with a complexity of 2 27round XTEA encryptions. We also propose several attacks on GOST. First, we present a distinguishing attack on full-round GOST, which can dis...
