Truncated Differential Analysis of Round-Reduced RoadRunneR Block Cipher
Lightweight Block Cipher RoadRunneR
2016/2/23
RoadRunneR is a small and fast bitslice lightweight block cipher for low cost 8-bit processors proposed by Adnan Baysal and Sa ̈hap S ̧ahin in the LightSec 2015 conference. While most softwa...
Provable Security Evaluation of Structures against Impossible Differential and Zero Correlation Linear Cryptanalysis
Bent Function；Galois ring, Non Linearity
2016/2/23
Bent functions shows some vital properties among all combinatorial objects. Its links in combinatorics, cryptography and coding theory attract the scientific community to construct new class of bent f...

Truncated Differential Known-Key Attack Simon
2016/1/27
At Crypto 2015, Blondeau, Peyrin and Wang proposed a
truncated-differential-based known-key attack on full PRESENT, a nibble
oriented lightweight blockcipher with a SPN structure. The truncated
dif...
A Theoretical Study of Kolmogorov-Smirnov Distinguishers, Side-Channel Analysis vs. Differential Cryptanalysis
Side-channel distinguisher Confusion coefficient Kolmogorov- Smirnov analysis
2016/1/26
In this paper, we carry out a detailed mathematical study of
two theoretical distinguishers based on the Kolmogorov-Smirnov (KS)
distance. This includes a proof of soundness and the derivation of cl...
Total Break of Zorro using Linear and Differential Attacks
Zorro Differential Attack Linear Attack
2016/1/25
An AES-like lightweight block cipher, namely Zorro, was proposed in CHES 2013. While it has a 16-byte state, it uses only 4 S-Boxes per round. This weak nonlinearity was widely criticized, insofar as ...

2016/1/23
This paper presents differential fault analysis of the MICKEY family of stream ciphers, one of the winners of eStream project. The current attacks are of the best performance among all the attacks aga...
Differential Fault Analysis on the families of SIMON and SPECK ciphers
Lightweight Block Ciphers SIMON SPECK
2016/1/23
In 2013, the US National Security Agency proposed two new families of lightweight block ciphers: SIMON and SPECK. Currently, linear and differential cryptanalytic results for SIMON are available in ...
Impossible differential cryptanalysis of LBlock with concrete investigation of key scheduling algorithm
Impossible differential cryptanalysis key recovery attack
2016/1/23
Impossible differential cryptanalysis has been proved to be one of the most powerful techniques to attack block ciphers. Based on the impossible differential paths, we can usually add several rounds...

2016/1/23
Impossible differential attacks are among the most powerful forms of cryptanalysis against block ciphers. We present in this paper an in-depth complexity analysis of these attacks. We show an unifie...
Branching Heuristics in Differential Collision Search with Applications to SHA-512
hash functions cryptanalysis SHA-512
2016/1/23
In this work, we present practical semi-free-start collisions for SHA-512 on up to 38 (out of 80) steps with complexity 240.5 . The best previously published result was on 24 steps. The attack is b...
This paper presents a thorough analysis of the AEAD scheme NORX, focussing on differential and rotational properties. We first introduce mathematical models that describe differential propagation wi...
Improved Differential Cryptanalysis of Round-Reduced Speck
Lightweight block cipher Speck cryptanalysis
2016/1/23
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 b...
Multivariate Public Key Cryptography (MPKC) has been
put forth as a possible post-quantum family of cryptographic schemes.
These schemes lack provable security in the reduction theoretic sense,
and...
