The Rényi Smoothing Parameter and Its Applications in Lattice-Based Cryptography [PDF]

open access: yes
The smoothing parameter is a cornerstone concept in lattice-based cryptography. Traditionally defined using the \( L^{\infty} \) distance, this standard formulation can be overly stringent compared to the \( L^1 \) (or statistical) distance more commonly

$α$-leakage by Rényi Divergence and Sibson Mutual Information

open access: yes
For $\tilde{f}(t) = \exp(\frac{α-1}αt)$, this paper proposes a $\tilde{f}$-mean information gain measure. Rényi divergence is shown to be the maximum $\tilde{f}$-mean information gain incurred at each elementary event $y$ of channel output $Y$ and Sibson
