ENES PASALIC is an academic who published a paper in 2020 entitled Improved Security Evaluation of SPN Block Ciphers and its Applications in the Single-key Attack on S. ENES PASALIC published this work as part of a team: Zhang, Wenying. Here is a description of this work: In this paper, a new method for evaluating the integral property, truncated and impossible differentials for substitution-permutation network (SPN) block ciphers is proposed. The main assumption is an explicit description/expression of the internal state words in terms of the plaintext (ciphertext) words. By counting the number of times these words occur in the internal state expression, we can evaluate the resistance of a given block cipher to integral and impossible/truncated differential attacks more accurately than previous methods. More precisely, we explore the cryptographic consequences of uneven frequency of occurrences of plaintext (ciphertext) words appearing in the algebraic expression of the internal state words. This approach gives a new family of distinguishers employing different concepts such as the integral property,.
