Assesses post-quantum readiness in AI agents, indicating the need for a crypto-agility program.
AI agents carry cryptography across three durable surfaces: the identity they present, the channel they speak over, and the receipts they leave behind. Post-quantum readiness is not a one-time migration but a crypto-agility program, measurable per surface on six axes and five levels. This paper sets out that maturity model for AI agent systems, introduces Agent-CBOM, an agent-channel profile of the ratified Cryptographic Bill of Materials (CycloneDX / ECMA-424), as the inventory instrument, and reports a preliminary pattern: agent audit receipts are commonly signed with fixed classical signatures that no inventory lists for quantum-agility.Paper #2 of the PQC for AI Agents Series.
