CIA: Inferring the Communication Topology from LLM-based Multi-Agent Systems

📰 ArXiv cs.AI

Learn to infer communication topology in LLM-based multi-agent systems, a critical privacy risk, and understand its implications on system security

advanced Published 15 Apr 2026
Action Steps
  1. Read the CIA paper to understand the methodology for inferring communication topologies in LLM-based MAS
  2. Apply the CIA approach to a sample MAS to identify potential security vulnerabilities
  3. Analyze the inferred communication topology to identify bottlenecks and single points of failure
  4. Implement countermeasures to protect the communication topology, such as encryption or secure communication protocols
  5. Test and evaluate the effectiveness of the countermeasures in preventing topology inference
Who Needs to Know This

Researchers and developers working on LLM-based multi-agent systems, particularly those focusing on security and privacy, can benefit from understanding how to infer communication topologies and mitigate potential risks

Key Insight

💡 LLM-based MAS communication topologies can be inferred under black-box settings, posing significant security risks
