Abstract
The purpose of this paper is to explore the differences and relations between the protocols CoAP, OSCORE, DTLS and HTTPS. Our focus is at performance and the general security benefits of the different protocols. We evaluate the feasibility of using CoAP encrypted with OSCORE or DTLS as opposed to using HTTPS/1.1 or HTTPS/3. We find the CoAP based solutions to be more performant than HTTPS, however we also find them to be harder to implement, less widespread and potentially more insecure than HTTPS. From these findings, in most scenarios we recommend implementing solutions based on HTTPS if the performance and overhead can be tolerated.
