Migration to Post-Quantum Cryptography project (NIST NCCoE)
The National Cybersecurity Center of Excellence (NCCoE) is collaborating with stakeholders in the public and private sectors to bring awareness to the challenges involved in migrating from the current set of public-key cryptographic algorithms to quantum-resistant algorithms.
Other models related to CAMM and/or cryptographic agility
PKI maturity model (PKIMM)
A maturity model with a focus on public key infrastructures. In our best estimation, this initiative will have to deal with PQC migration issues in the not too distant future.
Alliance for Telecommunications Industry Solutions (ATIS)
ATIS proposes another framework, that introduces so called Crypto Agility Metrics in order for organizations to
measure, assess, and enhance their preparedness for the shift to quantum-safe cryptography.
Tools for (Automated) Cryptographic Inventories (cf. CAMM requirement 1.4).
Although for the first tool, PQC algorithms are not yet tested here, this tool could be used as a starting point for a tool that helps to build a cryptography inventory
