ABSTRACT
In this paper, we propose DNS over CoAP (DoC). DoC provides the opportunity to enable confidential exchange of DNS messages in the Internet of Things (IoT) but introduces challenging research questions regarding the protocol design before we can unfold its full potential. We propose a research agenda to answer these questions in future work.

Recommendations
Securing Name Resolution in the IoT: DNS over CoAP
PACMNETIn 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 ...
IoT Protocols – MQTT versus CoAP
NISS '21: Proceedings of the 4th International Conference on Networking, Information Systems & SecurityThe usage of Internet of Things has increased in the recent years allowing a new way of connecting devices together. Many transactions happen over the IoT calling for protocols to ensure the efficiency and management of the communication traffic. This ...
SecureSense
Constrained Application Protocol (CoAP) has become the de-facto web standard for the IoT. Unlike traditional wireless sensor networks, Internet-connected smart thing deployments require security. CoAP mandates the use of the Datagram TLS (DTLS) protocol ...
