When AI Agents Collaborate: Implications for Post-Quantum Cryptography

The emergence of increasingly autonomous and collaborative AI agents introduces new opportunities and security challenges for the transition to post-quantum cryptography (PQC).

Using the reported Hugging Face incident involving AI agents as a case study, this presentation examines the distinctions between AI capability, agency, autonomy and authority, and explores the implications of emergent multi-agent behaviour for cybersecurity.

Could collaborative AI agents accelerate cryptographic discovery, migration, testing and verification? Conversely, what new risks arise when autonomous systems interact, cross operational boundaries or act without adequate human oversight?

The presentation considers how AI agents might support the PQC transition while emphasising the importance of secure agent identities, governance, bounded autonomy and human accountability.
