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...
Rounded Gaussians -- Fast and Secure Constant-Time Sampling for Lattice-Based Crypto
Post-quantum cryptography lattice-based cryptography sig- natures
2017/10/25
This paper suggests to use rounded Gaussians in place of dis- crete Gaussians in rejection-sampling-based lattice signature schemes like BLISS. We show that this distribution can efficiently be sample...
