The Relationship between the Construction and Solution of the MILP Models and Applications
MILP Gurobi PRESENT
2019/1/26
The automatic search method based on Mix-integer Linear Programming (MILP) is one of the most common tools to search the distinguishers of block ciphers. For differential analysis, the byte-oriented M...
Improving the MILP-based Security Evaluation Algorithms against Differential Cryptanalysis Using Divide-and-Conquer Approach
Block Cipher Differential Cryptanalysis MILP
2019/1/9
In recent years, Mixed Integer Linear Programming (MILP) has been widely used in cryptanalysis of symmetric-key primitives. For differential and linear cryptanalysis, MILP can be used to solve the two...

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...
Cube-Attack-Like Cryptanalysis of Round-Reduced Keccak Using MILP
Ketje Xoodoo Keccak-MAC
2018/11/19
Cube-attack-like cryptanalysis on round-reduced Keccak was proposed by Dinur et al. at EUROCRYPT 2015. It recovers the key through two phases: the preprocessing phase for precomputing a look-up table ...
