Roadmap to Secure 6G Networks

The evolution toward sixth-generation (6G) wireless communication networks introduces unparalleled opportunities, alongside complex security and privacy challenges. This paper presents a broad and flexible roadmap for securing 6G networks, exploring the diverse range of threats posed by advanced technologies such as Distributed Ledger Technology (DLT), quantum computing, and AI/ML. Rather than focusing on a singular problem or solution, the paper emphasizes the need for adaptable frameworks capable of addressing the multifaceted and evolving security landscape of 6G. Key areas of focus include quantum-safe cryptography, AI-based threat detection, and privacy-preserving technologies like homomorphic encryption and federated learning. The paper also underscores the critical role of standardization efforts by key organizations such as ETSI, ITU, and 3GPP in shaping secure, resilient, and trustworthy 6G networks. By maintaining a general perspective, this roadmap offers a foundation for future research and collaboration, guiding the development of context-specific security solutions as 6G technology advances.
