Viimeaikoina erilaiset tavat ker\u00e4t\u00e4 tietoa ja ohjata laitteita uusin tavoin ovat yleistyneet esimerkiksi teollisuudessa, kaupunkiymp\u00e4rist\u00f6jen melun ja saasteiden seurannassa.

New ways to gather more data and control devices are developed in many application areas from smart homes and cities, surrounding environments in cities as well as agricultural settings to industrial settings. This growth is due to miniaturization and the dropping costs. In order to deploy IoT applications in truly pervasive manner the physical size and cost of the devices should remain small. This means especially that in order to keep the cost low some of the device capabilities will be having constraints even when technologies evolve and the price might drop. The compromise is always going to be between narrower deployments with more capable devices and wider deployments with less capable devices. Wireless communication is in many cases the most economic way and for this reason Wireless Sensor Networks (WSN's) have been used in industrial settings for some time now. The same networking technologies can be used in constrained IoT devices. Many of the current WSN deployments are based on proprietary technologies and do not offer a secure end-to-end communication. Instead they provide the data for the Internet through gateways translating the WSN communication. The communication security is based on settings provided in the time of provisioning the devices. End-to-end connectivity and security can be realized by using IP-based protocols developed for constrained devices. But dynamic access control for these environments is still more or less an open question. A dynamic authorized authentication mechanism would make the systems even more integratable and easily maintainable. This paper deals with the problem field of conducting dynamic authorized authentication in constrained environments. The main artifact of this study is a framework that identifies both the constraints and security objectives for realizing authorized authentication in constrained environments.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Janne Poikolainen (jajupoik) on 2016-08-08 11:53:41.184706.
