🤖 AI Summary
Current cryptographic agility lacks an interpretable, assessable maturity model. Method: This paper proposes the first hierarchical, quantitative cryptographic agility maturity framework, structured across four dimensions—policy, process, technology, and personnel—and defining five progressive maturity levels with corresponding evaluation metrics. It integrates CMMI-inspired modeling principles, Delphi expert consensus, and industry practice mapping analysis. Contribution/Results: The framework significantly enhances the measurability and improbability of organizational dynamic adaptability—including cryptographic algorithm replacement, protocol updates, and key management. Preliminary validation in financial and governmental sectors demonstrates its effectiveness in improving the scientific rigor and operational feasibility of cryptographic migration planning. Moreover, it serves as an interpretable, practitioner-friendly assessment tool for educational outreach, such as cultivating cryptographic literacy among secondary school students.
