Abstract
The Internet of Things (IoT) is a common attack vector and cause for privacy concerns. Protecting against such attacks while also protecting the privacy of its users often conflicts with constrained resources we find in the IoT. We present DNS over the Constrained Application Protocol (CoAP), a new protocol to counter such attacks by encrypting queries, similar to DNS over TLS, HTTPS, or QUIC. In contrast to those protocols for the "big" Internet, DNS over CoAP is designed to encrypt queries from constrained IoT devices. It only requires a handful of kilobytes of working and perstistant flash memory and can be sent over small link layer PDUs. All while offering the same security properties as the other DNS over X protocols.

Martine Lenders is a last year PhD student at Freie Universität Berlin (FU Berlin) and a research associate at the Chair of Distributed and Networked Systems at Technische Universität Dresden (TU Dresden), supervised by Prof. Dr. Matthias Wählisch. Before joining TU Dresden, she graduated with a BSc and MSc in Computer Science from FU Berlin. Her research focuses on networking and programming for the Internet of Things (IoT). Through her engagement into all things IoT and network protocols, she is also involved with the development of the IoT operating system RIOT since 2011 and its maintenance since 2013. Additionally, she is active in the Internet Engineering Task Force (IETF) since 2015 where she recently co-authored RFCs 9952 and 9953.
