Truncated and Multiple Differential Cryptanalysis of Reduced Round Midori128

Midori is a family of SPN-based lightweight block ciphers designed to optimize the hardware energy consumption per bit during the encryption and decryption operations. At ASIACRYPT 2015, two variants of the cipher, namely Midori128 and Midori64, which support a 128-bit secret key and a 64/128-bit block, respectively, were proposed. Recently, a meet-in-the… (More)
