Advancing Secure and Private Communication: A Post-Quantum Mix-Net Approach

点击翻译按钮获取中文摘要

Traffic analysis of widely available metadata allows for location tracking, mass surveillance, and targeted attacks from adversaries. Mix Networks, a promising anonymous communication routing protocol, offers scalable anonymity against global adversaries, and are less prone to metadata attacks than more commonly used methods, such as onion routing. However, as this is an emerging area of research, there is a need for enhancing protocol performance, reliability, and agility. Furthermore, motivated by the threat posed by quantum computers to conventional encryption methods, this research also aims to address the integration of post-quantum cryptographic algorithms with mix network protocols. By bridging the gap between secure communication and privacy technologies, this research not only strives to enhance user privacy and data protection but also contributes to the broader development of anonymous communication methods and post-quantum cryptography.
