Description
Today's modern hardware, with manycore servers, RDMA-capable networks and trusted execution environments, challenges the conventional wisdom about CFT protocols' design. We explore the synergy between modern hardware and the security and performance of strongly consistent replication protocols. Specifically, can we leverage (and how) modern cloud hardware to harden the security properties of a CFT protocol for Byzantine settings while achieving high performance?
We propose Recipe, a generic approach to transform existing CFT protocols to tolerate Byzantine failures in untrusted cloud environments. Recipe leverages advances in confidential computing and direct network I/O to guarantee non-equivocation and transferable authentication in the presence of Byzantine actors, while offering performance and resource overheads on par with CFT protocols. Our evaluation based on the transformation of four CFT protocols against the state-of-the-art BFT protocols shows that Recipe can increase throughput up to 5.9×—24× and reduce the number of participating nodes by f.
