Contribution

It introduces a novel key expansion approach that preserves anonymity in voting systems using existing PKI infrastructure and elliptic curve cryptography.

Findings

Enables anonymous voting with certificate verification

Maintains end entity anonymity from authorities

Utilizes elliptic curve cryptography for security

Abstract

This document focuses on developing a key expansion method based on the internet X.509 public key infrastructure and elliptic curve cryptography, which is applied in the context of anonymous voting. The method enables end entities to maintain anonymity from other end entities, the registration authority, and the certificate authority, while still allowing the validity of end entity certificates to be verified, thereby facilitating anonymous voting services.
