Efficiently Masking Binomial Sampling at Arbitrary Orders for Lattice-Based Crypto
Masking Post-quantum Cryptography
2019/8/8
With the rising popularity of lattice-based cryptography, the Learning with Errors (LWE) problem has emerged as a fundamental core of numerous encryption and key exchange schemes. Many LWE-based schem...
Pseudorandom functions (PRFs) are one of the fundamental building blocks in cryptography. We explore a new space of plausible PRF candidates that are obtained by mixing linear functions over different...
Observations on the Dynamic Cube Attack of 855-Round TRIVIUM from Crypto'18
Dynamic Cube attack Division Property MILP
2018/11/6
Recently, another kind of dynamic cube attack is proposed by Fu et al. With some key guesses and a transformation in the output bit, they claim that, when the key guesses are correct, the degree of th...
A Refinement of “A Key-recovery Attack on 855-round Trivium" From CRYPTO 2018
Trivium Nullification Technique Polynomial Reduction
