چکیده

This paper presents differential attacks on Simon and Speck, two families of lightweight block ciphers that were presented by the U.S. National Security Agency in June 2013. We describe attacks on up to slightly more than half the number of rounds. While our analysis is only of academic interest, it demonstrates the drawback of the intensive optimizations in Simon and Speck.

Improved 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 ...

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...

MILP-aided Cryptanalysis of Round Reduced ChaCha

The inclusion of ChaCha20 and Poly1305 into the list of supported ciphers in TLS 1.3 necessitates a security evaluation of those ciphers with all the state-of-the-art tools and innovative cryptanalysis methodologies. Mixed Integer Linear Programming (MILP) has been successfully applied to find more accurate characteristics of several ciphers such as SIMON and SPECK. In our research, we use MILP...

Differential Analysis on Simeck and SIMON with Dynamic Key-guessing Techniques

The Simeck family of lightweight block ciphers was proposed in CHES 2015 which combines the good design components from NSA designed ciphers SIMON and SPECK. Dynamic key-guessing techniques were proposed by Wang et al. to greatly reduce the key space guessed in differential cryptanalysis and work well on SIMON. In this paper, we implement the dynamic key-guessing techniques in a program to auto...

Impossible Differential Cryptanalysis of Reduced-Round Midori64 Block Cipher (Extended Version)

Impossible differential attack is a well-known mean to examine robustness of block ciphers. Using impossible differ- ential cryptanalysis, we analyze security of a family of lightweight block ciphers, named Midori, that are designed considering low energy consumption. Midori state size can be either 64 bits for Midori64 or 128 bits for Midori128; however, both vers...
