On-demand security configuration for IoT devices

IoT, as one of the main focuses, links various kinds of devices to the Internet and even exchanges its data. The advent of IoT which has vast amount of connected devices enables us to monitor and control of real world and changes our daily lifestyle never available before. With such a massive amount of devices, if we don't set and organize security features on them properly, we will face unexperienced challenges on security issues. In this paper we propose the on-demand security configuration technique that we can configure required security functions and reorganize them without recreating device image. With the help of this approach, if there is a change on this security service, we can substitute the old modules for new ones without regenerating device image.
