Abstract

The rising popularity of the Internet of Things (IoT) on a global scale has led to an increase in cyber threats, and researchers are paying more attention to its security issues. So far, research on IoT security has focused on large-scale devices, but there is relatively less research on the security of small IoT devices. Therefore, our objective is to mainly study how to make the operation of small IoT devices safer. Raspberry House is a TCP/IP Layer 3 gateway built with Raspberry Pi, which can connect IoT devices to the private network generated by it, thereby preventing IoT devices from being exposed to outside networks. In addition, through a private network, IoT devices can also update their firmware wirelessly. This paper also studies the communication between IoT devices through different secure connections such as Secure Shell (SSH), and evaluates their results in different environments. Experimental evaluation of TCP/IP Layer 3 Gateway indicates that the proposed framework can provide security for small IoT devices.
