Analysis of Error Dependencies on Newhope
IEEE Access, 2020 Among many submissions to NIST post-quantum cryptography (PQC) project, NewHope is a promising key encapsulation mechanism (KEM) based on the Ring-Learning with errors (Ring-LWE) problem.

Obfuscating Conjunctions under Entropic Ring LWE [PDF]
Proceedings of the 2016 ACM Conference on Innovations in Theoretical Computer Science, 2016 We show how to securely obfuscate conjunctions, which are functions f(x1,...,xn) = ∧i∈I yi where I ⊆ [n] and each literal yi is either just xi or ¬ xi e.g., f(xi,...,x_n) = xi ⊆ ¬ x3 ⊆ ¬ x7 ... ⊆ x{n-1. Whereas prior work of Brakerski and Rothblum (CRYPTO 2013) showed how to achieve this using a non-standard object called cryptographic multilinear maps,

Integer Version of Ring-LWE and its Applications [PDF]
, 2021 In this work, we describe an integer version of ring-LWE over the polynomial rings and prove that its hardness is equivalent to one of the polynomial ring-LWE.

Implementing Conjunction Obfuscation Under Entropic Ring LWE [PDF]
2018 IEEE Symposium on Security and Privacy (SP), 2018 We address the practicality challenges of secure program obfuscation by implementing, optimizing, and experimentally assessing an approach to securely obfuscate conjunction programs proposed in [1]. Conjunction programs evaluate functions f (x_1,...,x_L) = wedge_i in _I y_i, where y_i is either x_i or -x_i and I subseteq [L], and can be used as ...

Provably Weak Instances of Ring-LWE Revisited [PDF]
, 2016 In CRYPTO 2015, Elias, Lauter, Ozman and Stange described an attack on the non-dual decision version of the ring learning with errors problem RLWE for two special families of defining polynomials, whose construction depends on the modulusq that is being used.

Tightly Secure Ring-LWE Based Key Encapsulation with Short Ciphertexts [PDF]
, 2017 We provide a tight security proof for an IND-CCA Ring-LWE based Key Encapsulation Mechanism that is derived from a generic construction of Dent (IMA Cryptography and Coding, 2003). Such a tight reduction is not known for the generic construction.
