Security architecture elements for IoT enabled automation networks

Internet of Things (IoT) technologies have recently gained a lot of interest from numerous industries, where devices, machines, sensors, or simply things are talking to each other over standard Internet technologies. The objectives of the EU project IoT@Work are to transfer Internet of Things approaches to industrial automation environments and to develop mechanisms and protocols to enable plug & work of devices. This introduces new security challenges as the current security solutions based on perimeter protection are not sufficient as single measure for Internet of Things enabled industrial automation environments This paper introduces additional security architecture elements being researched in the EU project IoT@Work in a general way and with focus on the network and device related aspects.
