Security optimization of IoT platforms based on named data networking

When it comes to developing a smart system involving sensors and actuators, there are two main problems to be addressed: what platform to be used as infrastructure and how to develop the security layer? In this paper, Orion Context Broker (OCB) is chosen for data management, while security layer is composed by Named Data Networking (NDN) and FIWARE modules (IdM KeyRock and Wilma PEP Proxy). The work was focused on data confidentiality and integrity because this is an important aspect of an IoT system. Store capabilities of OCB were extended from one value for an attribute to long term store archive. This approach is benefic for obtaining data necessary for statistics and predictions, where historical data must be used.Peer ReviewedPostprint (published version
