IoT Border Gateway Remote Access and Security in Connecting Multiple IoT Autonomous Systems

This thesis aims to find the best approach to remote access and security in connecting multiple IoT Autonomous Systems over the Internet. Currently, remote access and security is achieved through traditional technologies such as VPN, port forwarding and proxies. However, these technologies were not designed specifically for IoT. This makes them subject to a number of shortcomings in regards to authentication, authorization and accounting. To overcome these limitations, the IoT Border Gateway (BGW) is introduced. The BGW consists of External Interface, HTTP Proxy, MQTT Proxy, Auth Server and AAA Client. The resulting BGW is evaluated by measuring the throughput and comparing it against state of the art.
