Differential Cryptanalysis of Reduced-Round Simon
In June 2013 the U.S. National Security Agency proposed two families of ultra-lightweight block ciphers, called Simon and Speck. In this paper we present the first cryptanalysis of round-reduced versions of Simon. We mount differential distinguishers and key-recovery attacks on up to 14/32, 17/36, 21/44, 26/54, and 32/72 rounds, for the 32-, 48-, 64-, 96-, and 128-bit versions, respectively. Fu...
متن کاملDifferential Cryptanalysis of a Reduced-Round SEED
We analyze the security of the SEED block cipher against di erential attacks. SEED is a 16-round Feistel cipher developed by the Korea Information Security Agency. The SEED proposers estimated their cipher against di erential cryptanalysis in a self-estimation document and found a six-round di erential characteristic with probability 2 130 . We present an improved method of examining the di ere...
متن کاملImproved Differential Cryptanalysis of Round-Reduced Speck
Simon and Speck are families of lightweight block ciphers designed by the U.S. National Security Agency and published in 2013. Each of the families contains 10 variants, supporting a wide range of block and key sizes. Since the publication of Simon and Speck, several research papers analyzed their security using various cryptanalytic techniques. The best previously published attacks on all the ...
متن کاملImpossible Differential Cryptanalysis of Reduced Round SIMON
Impossible differential is a useful method for cryptanalysis. SIMON is a light weight block cipher that has attracted lots of attention ever since its publication in 2013. In this paper we propose impossible differential attack on five versions of SIMON, using bit conditions to minimize key bits guessed. We calculate keybits and give the exact attack results.
متن کاملImpossible Differential Cryptanalysis of Reduced-Round SKINNY
SKINNY is a new lightweight tweakable block cipher family proposed by Beierle et al. at CRYPTO 2016. SKINNY has 6 main variants where SKINNY-n-t is a block cipher that operates on n-bit blocks using t-bit tweakey (key and tweak) where n = 64 or 128 and t = n, 2n, or 3n. In this paper, we present impossible differential attacks against reduced-round versions of all the 6 members of the SKINNY fa...
