The Domain Name System (DNS) used on the Internet to provide an effective correspondence between network identifiers and their user-friendly variants, is based on a highly stable, optimised and resilient architecture. However, maintaining the efficiency of the underlying protocols has not allowed them to keep pace with the rest of the Internet. The introduction of the REST paradigm has nevertheless paved the way for the evolution of DNS via its RESTification. However, the latter
leads to an increase in latency and verbosity, which could ultimately compromise its widespread use. In this thesis we focus on reducing the impact of RESTification on DNS. Leveraging advances in the Internet of Things, we make two significant contributions concerning the size of data carried by protocols, and DNS architecture. We define a new format based on CBOR for efficient encoding of DNS messages. We present a new representation, called efficient CBOR (e-CBOR), which provides
compact and flexible DNS/DNSSEC formats while maintaining compatibility with existing protocols. Tests performed on the e-CBOR implementation show a significant reduction in message size compared to messages encoded in the traditional format. The second contribution concerns the design and implementation of a new entity called DNSBroker. It allows private DNS resolutions to control access to network resources, while reducing the number of messages exchanged when these resolutions are authorised. A demonstrator allows us to validate the relevance of our proposals by applying them to the use case of roaming between LoRaWAN network operators.
