Research and implementation of access control model of internet of things

With the development of internet of things (IOT), the current focus of research has turned from the “material connected” to the open platform implementation of IOT [1]. In security considerations, authority management must be taken into consideration when we build open platform of IOT. Usually, authority management can be implemented by the access control model that is running in the open platform. In this paper, we analyze some popular solutions to authority management in open platform of Internet, and then put up a new access control model that can distribute permissions flexibly, simply which means authority manager can manage authorities pretty easily, and authorities can be allocated in a real-time, dynamic condition, which meets the features of IOT[2]. It can be a good solution to authority management in an open platform of IOT.
