Masking ring-LWE [PDF]

Journal of Cryptographic Engineering, 2016
In this paper, we propose a masking scheme to protect ring-LWE decryption from first-order side-channel attacks. In an unprotected ring-LWE decryption, the recovered plaintext is computed by first performing polynomial arithmetic on the secret key and then decoding the result. We mask the polynomial operations by arithmetically splitting the secret key

Compact Ring-LWE Cryptoprocessor [PDF]

Lecture Notes in Computer Science, 2014
In this paper we propose an efficient and compact processor for a ring-LWE based encryption scheme. We present three optimizations for the Number Theoretic Transform NTT used for polynomial multiplication: we avoid pre-processing in the negative wrapped convolution by merging it with the main algorithm, we reduce the fixed computation cost of the ...

Efficient Ring-LWE Encryption on 8-Bit AVR Processors [PDF]

Lecture Notes in Computer Science, 2015
Public-key cryptography based on the “ring-variant” of the Learning with Errors (ring-LWE) problem is both efficient and believed to remain secure in a post-quantum world. In this paper, we introduce a carefully-optimized implementation of a ring-LWE encryption scheme for 8-bit AVR processors like the ATxmega128.

A Note on Ring-LWE Security in the Case of Fully Homomorphic Encryption [PDF]

Lecture Notes in Computer Science, 2017
Evaluating the practical security of Ring-LWE based cryptography has attracted lots of efforts recently. Indeed, some differences from the standard LWE problem enable new attacks. In this paper we discuss the security of Ring-LWE as found in Fully Homomorphic Encryption (FHE) schemes. These FHE schemes require parameters of very special shapes, that an
