Improved lattice enumeration algorithms by primal and dual reordering methods

IET Information Security, Volume 17, Issue 1, Page 35-45, January 2023., 2023
Abstract The security of lattice‐based cryptosystems is generally based on the hardness of the Shortest Vector Problem (SVP). The original enumeration (ENUM) algorithm solving SVP runs in exponential time due to the exhaustive search, which is used as a subroutine for the block Korkin–Zolotarev (BKZ) algorithm.

Improved lattice‐based mix‐nets for electronic voting

IET Information Security, Volume 17, Issue 1, Page 18-34, January 2023., 2023
Abstract Mix‐networks were first proposed by Chaum in the late 1970s–early 1980s as a general tool for building anonymous communication systems. Classical mix‐net implementations rely on standard public key primitives (e.g., ElGamal encryption) that will become vulnerable when a sufficiently powerful quantum computer will be built.

Crystals‐Dilithium on ARMv8

Security and Communication Networks, Volume 2022, Issue 1, 2022., 2022
Crystals‐Dilithium is one of the digital‐signature algorithms in NIST’s ongoing post‐quantum cryptography (PQC) standardization final round. Security and computational efficiency concerning software and hardware implementations are the primary criteria for PQC standardization.

A Decentralized Electronic Reporting Scheme with Privacy Protection Based on Proxy Signature and Blockchain

Security and Communication Networks, Volume 2022, Issue 1, 2022., 2022
The electronic reporting system can alleviate the problems in terms of efficiency, content confidentiality, and reporter privacy imposed in the traditional reporting system. Relying on anonymity, the privacy of reporters can be protected, but the authentication of reporters with fake names should also be maintained.
