Securing Multi-Agent Systems for Near Real-Time Control of 6G Services

Abstract

Multi-agent systems (MAS) have been proposed as an alternative to traditional centralized control for near real-time service control. However, MAS also show a distributed attack surface. To overcome their software higher security exposure, we combine a set of scalable techniques fostering enhanced security applied on individual agents and their communications. Specifically, the proposed solution combines: <em>i</em>) binary hardening with secure execution monitoring; <em>ii</em>) distributed ledger technologies for non-real-time MAS management; and <em>iii</em>) VXLAN and encrypted communications for near real-time MAS operation. The solution is designed not only to provide strong security to the MAS, but also to minimize any functional overhead.
