MeshDNS: A Cooperative DNS Resolution Framework for Resource-Constrained IoT Networks

This feed contains multiple networking and IoT research papers with several security-relevant implications. The lead paper, MeshDNS, describes a decentralized cooperative DNS resolution framework for resource-constrained IoT nodes (ESP8266-class) that uses hash-based cache summaries and Ed25519-signed quorum voting to secure cold-cache misses under a shared-key admission model; the authors explicitly exclude physical hardware key extraction from the threat model. Security trade-offs include a measurable cryptographic latency for cold-cache resolution and reliance on shared-key admission, which
