Securing Infiniband Networks with End-Point Encryption
Abstract
The NVIDIA-Mellanox BluexC;eld-2 is a 100 Gbps high-performance network interface which offers hardware offload and acceleration features that can operate directly on network traffic without routine involvement from the ARM CPU. This allows the ARM multi-core CPU to orchestrate the hardware to perform operations on both Ethernet and RDMA traffic at high rates rather than processing all the traffic directly. A testbed called TNAP was created for performance testing and a MiTM verixC;fication process called MiTMVMP is used to ensure proper network conxC;figuration. The hardware accelerators of the BluexC;eld-2 support a throughput of nearly 86 Gbps when using IPsec to encrypt and authenticate RoCEv2 traffic. This research closes by providing operational security recommendations to defend against presented vulnerabilities, and secure InxC;finiBand with the BluexC;eld-2 DPU and similar InxC;finiBand channel adapters.
