A Distributed Security Scheme to Secure Data Communication between Class-0 IoT Devices and the Internet

Abstract [en]

This thesis focuses on securing data exchanged between highly constrained IoT devices and the internet. This thesis builds on existing research by combining elements of different research solutions to create a more secure solution. This solution helps to solve gaps in security left behind by existing solutions through the use of symmetric cryptography in data objects and IoT security gateways which act as intermediaries between devices and the internet. The goal of this research is to provide a security solution for devices which do not have the resources necessary to effectively implement the recommended TLS based protocols for secure communication over the internet. The solution provides confidentiality to data traveling between device and gateway while also providing confidentiality, integrity and authenticity to data traveling across the internet. The solution works by delegating demanding security processes to an IoT security gateway which securely processes communications to and from the internet using HTTPS (SSL/TLS). Security of data being passed between device and gateway is provided with AES symmetric encryption at the Data Link and Data Object layers. The performance of the solution is measured by timing the security process of the IoT device while also measuring the resource requirements of applying the solution to the device.
