Improved security evaluation of SPN block ciphers and its applications in the single-key attack on SKINNY

Improved security evaluation of SPN block ciphers and its applications in the single-key attack on SKINNY

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)...
