Cryptanalytic study reveals a 15-round attack on Midori-64, highlighting security vulnerabilities in lightweight block ciphers.
Midori is a lightweight block ciphers presented by Banik et al. and the 128-bit master key K directly generates the round key RKi.We mostly focus on the related-key differential cryptanalysis on Midori-64.By analyzing the DDT of S-box, we find that some differences can remain the same with the high probability and obtain 2-round invariant subspace of Midori-64.Then, we find two 11-round related-key differential distinguishers for Midori-64 with the probability of 2 -48 and 2 -54 .Using the second differential distinguisher, we present a 15-round related-key differential cryptanalysis on Midori-64 with data complexity of 2 55 and time complexity of 2 108.11 .
