Efficient Security Protocol for RESTful IoT devices

Sammanfattning: In this thesis, we presented comparisons with respect to Energy Consumption, bandwidth, the Constraint application protocol (CoAP) transaction time and throughput for four different security protocols. We simulated and implemented the Datagram Transport Layer Protection (DTLS) version 1.2, Transport Layer Protocol (TLS) version 1.2 & 1.3, and Object Protection for Restricted RESTful Environments (OSCORE). All of the above security protocols allow client/server applications to communicate over the internet with message forgery, eavesdropping, and tampering protection. In particular, we compared the simulation and implementation results of the mentioned protocols to extrapolate the performance of the DTLS version 1.3.
