Messaging Layer Security (MLS) in RFC 9420 scales cryptographically, but overlapping group-state updates are still committed against a single epoch, and stale attempts must be retried. This is tolerable in small groups but creates avoidable delay and extra fan-out traffic in large, bursty deployments. We propose a Dece...

Radio frequency fingerprint identification (RFFI) is increasingly proposed as a lightweight physical-layer authentication primitive for Internet-of-Things and edge devices, but deep RFFI models remain vulnerable to adversarial manipulation. This paper studies a narrow and realistic version of that problem: can a black-...

Spatial Crowdsourcing (SC) coordinates workers and requesters through personal mobile devices to complete location‐dependent tasks in real time. The combination of continuous worker mobility, self‐interested participants, and real‐time service requirements creates a learning environment that is more adversarial, more...
