Efficient Search for Optimal Diffusion Layers of Generalized Feistel Networks
Diffusion Round Feistel Permutations
2019/5/23
The Feistel construction is one of the most studied ways of building block ciphers. Several generalizations were then proposed in the literature, leading to the Generalized Feistel Network, where the ...
Shuffle and Mix: On the Diffusion of Randomness in Threshold Implementations of Keccak
side-channel analysis threshold implementation uniformity
2018/11/13
Threshold Implementations are well-known as a provably firstorder secure Boolean masking scheme even in the presence of glitches. A precondition for their security proof is a uniform input distributio...
