Differential Fault Analysis of MICKEY Family of Stream Ciphers
MICKEY-128 2.0 MICKEY v1 MICKEY 2.0
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...
Improved Impossible Differential Attacks against Round-Reduced LBlock
block ciphers impossible differential attacks LBlock
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...
Differential Attacks on Reduced SIMON Versions with Dynamic Key-guessing Techniques
SIMON lightweight block cipher bit condition
2016/1/9
SIMON is a family of lightweight block ciphers which are
designed by the U.S National Security Agency in 2013. It has totally
10 versions corresponding to different block size 2n and key length

The lightweight block cipher PRIDE designed by Albrecht
et al., appears in CRYPTO 2014. The designers claim that their method
of constructing linear layer is good both in security and efficiency. In...

Analysis of Boomerang Differential Trails via a SAT-Based Constraint Solver URSA
Boomerang Differential Trails SAT-Based Constraint Solver URSA
2016/1/8
In order to obtain differential patterns over many rounds of a cryptographic primitive,
the cryptanalyst often needs to work on local differential trail analysis. Examples include
merging two differ...
On the Optimality of Differential Fault Analyses on CLEFIA
CLEFIA Differential Fault Analysis Fault Attack
2016/1/8
Differential Fault Analysis is a powerful cryptanalytic tool to reveal secret keys of cryptographic algorithms. By corrupting the computation of an algorithm, an attacker gets additional information a...
