ABSTRACT
The Internet of Things has become the latest point of interest in the IT industry. Due to this, many companies and individuals are beginning to make new innovations and conduct more research regarding IoT. As it always is when new IT innovations emerge, information security is a must, hence there has been researches on what the ideal security measures should be when it comes to IoT. However, one problem in IoT is with each new infrastructure and different security protocols are implemented. There is also no authentication and authorization protocol that can handle different types of infrastructures in one internetwork. The aim of this study is to make a system that can authorize and authenticate devices joining an IoT network, regardless of their infrastructure. With the proposed system, different infrastructure devices were able to communicate with one another. A device running on 802.15.4 was able to send a 256-byte packet to a device running on 802.11 with a latency of 300.111 milliseconds, while a device running on 802.11 was able to send a 256-byte packet to a device running on 802.15.4 with a latency of 1035.087 milliseconds.
