TAS-GNN: A Status-Aware Signed Graph Neural Network for Anomaly Detection in Bitcoin Trust Systems

Collection of recent security- and privacy-relevant CS papers (arXiv 2026-03-17). Highlights: TAS-GNN — a topology- and status-aware signed GNN for anomaly detection in Bitcoin Web-of-Trust networks (improves detection of Sybil/camouflaged fraud); Prefix-Shared KV Cache (PSKV) — an inference optimization that reuses a prefix KV cache to accelerate suffix jailbreak candidate evaluation (reported ~40% runtime and ~50% peak memory reductions; code to be released), which can make suffix jailbreak red-teaming (and offensive testing) much cheaper; OpenClaw agent privilege separation — a structural,
