Securing name resolution in the IoT: DNS over CoAP. (arXiv:2207.07486v3 [cs.NI] CROSS LISTED)
cs.CR updates on arXiv.org arxiv.org
In this paper, we present the design, implementation, and analysis of DNS
over CoAP (DoC), a new proposal for secure and privacy-friendly name resolution
of constrained IoT devices. We implement different design choices of DoC in
RIOT, an open-source operating system for the IoT, evaluate performance
measures in a testbed, compare with DNS over UDP and DNS over DTLS, and
validate our protocol design based on empirical DNS IoT data. Our findings
indicate that plain DoC is on par with …
