Van-Linh Nguyen, Po-Ching Lin, Bo-Chao Cheng, Ren-Hung Hwang, Ying-Dar, Lin

TL;DR
This survey reviews prospective security and privacy challenges for 6G networks, highlighting new threat vectors, vulnerabilities inherited from previous generations, and promising defense techniques across multiple layers.
Contribution
It systematically analyzes 6G security issues, lessons from past failures, and potential innovative solutions like quantum-safe communications and AI security.
Findings
6G introduces new threat vectors from advanced radio technologies
Physical layer protection and AI security are key defense techniques
Emerging data protection methods include distributed ledgers and differential privacy
Abstract
Sixth-generation (6G) mobile networks will have to cope with diverse threats on a space-air-ground integrated network environment, novel technologies, and an accessible user information explosion. However, for now, security and privacy issues for 6G remain largely in concept. This survey provides a systematic overview of security and privacy issues based on prospective technologies for 6G in the physical, connection, and service layers, as well as through lessons learned from the failures of existing security architectures and state-of-the-art defenses. Two key lessons learned are as follows. First, other than inheriting vulnerabilities from the previous generations, 6G has new threat vectors from new radio technologies, such as the exposed location of radio stripes in ultra-massive MIMO systems at Terahertz bands and attacks against pervasive intelligence. Second, physical layer…
