There are traditional cyber threats and also new threats. There is no guard and immunity for systems against the innumerable variance of attack and exploitation. In this paper, an approach base on Polling System is presented for secure routing IoT devices.

Although the new IoT functionality of smart devices causes to the better life for the human, there are traditional cyber threats and also new threats. However there were many works on the IoT security, most of them were not Use-Centric. In against of the previous works, the proposed approach is base on the interaction with users, so it is User-Centric completely. In a broad view, we divide IoT networks into two categories: 1- consumer and 2- industrial. While we use IoT devices in a smart home, we emphasize on the smart point of the IoT devices. In other words, the ideal point of IoT devices is communicated and adjusting to other physical devices in the home. While a set of smart home devices has a particular behavior or need for special decision making, we called them as user-centric IoT (UCIoT) [10]. There is no guard and immunity for systems against the innumerable variance of attack and exploitation. Thus security mechanism has fought to keep with IoT. Intelligence is successful to detect the intruder. IoT has the challenge to bridge physical with the cyber world [11]. Previous security mechanisms must be adapted in order to maintain defensive expectation. In this paper, an approach base on Polling System is presented for secure routing IoT devices. In the classical view, Polling System is a set of one server and multiple queues. Clients are arrived and set into queues and then get server according to a particular policy. (figure 1)
