PARS: Post-Quantum IoT Blockchain Security for Mission-Critical Physical AI Agents

Addressing the threat quantum computers pose to public-key authentication and key agreement, the study proposes the "rotational secrecy" architectural objective and the PARS reference mechanism, which coordinates policy-triggered key establishment, rotation, and reconciliation among authorized Physical AI agents. The optional PARS-ESL permissioned chain, maintained by authorized validators or edge gateways, records only authentication state such as key epochs, group membership, revocation, and algorithm-suite policies, not high-frequency business transactions, allowing resource-constrained agents to join as lightweight clients.
