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

通过对广泛可用的元数据进行流量分析，可以进行位置跟踪、大规模监视和来自对手的定向攻击。MIX网络是一种很有前途的匿名通信路由协议，它提供了针对全球对手的可扩展匿名性，并且比更常用的方法(如洋葱路由)更不容易受到元数据攻击。然而，由于这是一个新兴的研究领域，因此需要提高协议的性能、可靠性和灵活性。此外，出于量子计算机对传统加密方法的威胁，本研究还旨在解决后量子密码算法与MIX网络协议的集成问题。通过弥合安全通信和隐私技术之间的差距，本研究不仅努力增强用户隐私和数据保护，而且有助于匿名通信方法和后量子密码学的更广泛发展。

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.
