Learn to navigate NVMe-over-Fabrics authentication mechanisms in this conference talk from SNIA Storage Developer Conference 2025. Explore the DH-HMAC-CHAP in-band authentication method for hosts and subsystems, and discover the newly introduced Authentication Verification Entity (AVE) - a logical entity designed to manage and verify authentication processes in centralized or semi-centralized deployments. Understand how AVE simplifies authentication key management and enhances security in large fabric deployments. Address critical implementation gaps in the NVMe specification, particularly around determining when to use single versus multiple authentication keys, and examine the challenges these ambiguities create for implementers regarding security risks, key isolation, and scalability. Gain insights from practical product development experience as the presenter discusses comprehensive recommendations identified in both the NVMe specification and open-source ecosystem. Presented by Swati Chawdhary from Samsung, this technical session provides essential guidance for storage professionals working with NVMe-oF authentication implementations.
