This presentation describes the need for collaborative multi-stakeholder involvement in research and modeling to inform the DNSSEC post-quantum cryptography (PQC) algorithm standardization and transition agenda. Some key issues that need to be researched are described. This includes DNSSEC's need for long-term cryptographic resiliency and the impact NIST's selected PQC signature algorithm signatures will have on DNS transport and DNSSEC-related memory and processing requirements. Categories of DNS protocol enhancements to address these issues are postulated. The need for collaborative multi-stakeholder research and modeling is then justified as a method for assessing the pros and cons of transport options and potential protocol enhancements. The talk concludes with a proposal for a research and modeling agenda to support the pros and cons assessment.
