KNX IoT Point API Overview
KNX is an international standard (ISO/IEC 14543, EN 50090) for commercial and domestic building automation. KNX IoT Point API is the new transport medium of KNX. This new transport medium is fully compatible with existing KNX technology, KNX/TP, KNX/RF and KNXnet/IP.
Many IoT protocols use DTLS encryption between endpoints, which need to be un-encrypted and re-encrypted in the presence of intermediaries such as proxies. In addition, DTLS cannot encrypt multicast messages. This adds points of vulnerability.
KNX IoT Point API uses Object Security for Constrained RESTful Environments (OSCORE) to encrypt all types of messages end-to-end between endpoints, even in the presence of intermediaries such as proxies.
