Our article, “Benchmarking of Secure Group Communication schemes with focus on IoT”, has been accepted for publication in the International Journal of Discover Data. With the proliferation of IoT devices comes an increase in cybersecurity threats. Unlike standard 1-to-1 communication, IoT requires efficient n-to-n encryption, which is achieved through Secure Group Communication schemes. However, the abundance of available schemes makes selecting the right one daunting. Our paper addresses this challenge by presenting a benchmark specifically tailored for IoT, assisting developers in their scheme selection process. We define business problems, design a specification-based benchmark, and extend it to a hybrid benchmark suitable for real-world IoT environments.
