Navigating NVMe-oF Authentication: Best Practices for Key Management in Pre-AVE and Post-AVE Deployments
NVMe-over-Fabrics (NVMe-oF) offers DH-HMAC-CHAP as its in-band method for authenticating hosts and subsystems. To enhance authentication capabilities, the specification recently introduced the Authentication Verification Entity (AVE) – a logical entity designed to manage and verify the authentication process. AVE enables centralized or semi-centralized authentication, simplifying the management of authentication keys and improving security in large fabrics deployments.
However, the specification lacks comprehensive guidelines on implementing authentication mechanisms, particularly in determining when to use single versus multiple authentication keys. This ambiguity existed before AVE and still persists after its addition. The absence of clear recommendations poses challenges for implementers, especially in managing security risks, key isolation, and scalability.
In this talk, we address these gaps by discussing all the recommendations from the NVMe Workgroup that we identified in the NVMe specification and the open-source ecosystem during our product development.
