Mixture Integral Attacks on Reduced-Round AES with a Known/Secret S-Box
AES Mixture Differential Cryptanalysis Secret-Key Distinguisher
2019/7/8
The starting point of our work is “Mixture Differential Cryptanalysis” recently introduced at FSE/ToSC 2019, a way to turn the “multiple-of-8” 5-round AES secret-key distinguisher presented at Eurocry...
Integral Matrix Gram Root and Lattice Gaussian Sampling without Floats
Lattice based cryptography Discrete Gaussian sampling Matrix decomposition
2019/4/1
Many advanced lattice based cryptosystems require to sample lattice points from Gaussian distributions. One challenge for this task is that all current algorithms resort to floating-point arithmetic (...
MILP Method of Searching Integral Distinguishers Based on Division Property Using Three Subsets
Division property using three subsets Integral distinguisher MILP
2018/12/11
Division property is a generalized integral property proposed by Todo at EUROCRYPT 2015, and then conventional bit-based division property (CBDP) and bit-based division property using three subsets (B...
Towards Key-Dependent Integral and Impossible Differential Distinguishers on 5-Round AES
AES Key-Dependent Integral
2018/8/10
Reduced-round AES has been a popular underlying primitive to design new cryptographic schemes and thus its security including distinguishing properties deserves more attention. At Crypto'16, a key-dep...
The division property method is a technique to determine integral distinguishers on block ciphers. While the complexity of finding these distinguishers is higher, it has recently been shown that MILP ...

2016/12/10
Division property is a generalized integral property proposed by Todo at EUROCRYPT 2015, and very recently, Todo et al. proposed bit-based division property and applied to SIMON32 at FSE 2016. However...
On the Design Rationale of SIMON Block Cipher: Integral Attacks and Impossible Differential Attacks against SIMON Variants
SIMON Lightweight block cipher Integral attack
2016/6/20
SIMON is a lightweight block cipher designed by NSA in 2013. NSA presented the specification and the implementation efficiency, but they did not provide detailed security analysis nor the design ratio...

CLEFIA Integral attack Zero-correlation linear cryptanalysis
2016/2/23
CLEFIA is a block cipher developed by Sony Corporation in 2007. It is a recommended
cipher of CRYPTREC, and has been adopted as ISO/IEC international standard in lightweight
cryptography. In this pa...
