We present commensal cuckoo, a secure group partition-
\ning scheme for large-scale systems that maintains the cor-
\nrectness of many small groups, despite a Byzantine adver-
\nsary that controls a constant (global) fraction of all nodes.
\nIn particular, the adversary is allowed to repeatedly rejoin
\nfaulty nodes to the system in an arbitrary adaptive man-
\nner, e.g., to collocate them in the same group. Commensal
\ncuckoo addresses serious practical limitations of the state-of-
\nthe-art scheme, the cuckoo rule of Awerbuch and Scheideler,
\ntolerating 32x{41x more faulty nodes with groups as small
\nas 64 nodes (as compared to the hundreds required by the
\ncuckoo rule). Secure group partitioning is a key component
\nof highly-scalable, reliable systems such as Byzantine fault-
\ntolerant distributed hash tables (DHTs).<\/p>\n","protected":false},"excerpt":{"rendered":"
