On the Leakage Resilience of Ring-LWE Based Public Key Encryption
Dana Dachman-Soled, Huijing Gong, Mukul Kulkarni, and Aria Shahverdi
Abstract
We consider the leakage resilience of the Ring-LWE analogue of the Dual-Regev encryption scheme (R-Dual-Regev for short), originally presented by Lyubashevsky et al.~(Eurocrypt '13). Specifically, we would like to determine whether the R-Dual-Regev encryption scheme remains IND-CPA secure, even in the case where an attacker leaks information about the secret key.
We consider the setting where
