Physical-layer Security Based Authentication and Key Generation for Seamless IoT Communications

Abstract Details

2019, Master of Science (M.S.), University of Dayton, Electrical and Computer Engineering.
The Internet-of-Things (IoT) will connect different types of cyber physical systems that are supported by different wireless transmission technologies, e.g., Wi-Fi, ZigBee, etc. However, the security protocols of those wireless technologies cannot be implemented to support seamless and secure IoT communications. Moreover, security protocols need to be light-weighted since some IoT devices have limited computation resources. In this thesis, we propose a light weight physical-layer security based authentication and key generation scheme to bridge different transmission technologies in IoT communications. In the studied scenario, a group certificate is generated based on physical-layer information, i.e., received signal strength (RSS) for all legitimate IoT devices in a network. The group certificate is to support mutual authentication between any pair of IoT devices within the network. Furthermore, the proposed scheme also generates a session key for the authenticated pair of IoT devices for other purposes of security features. The proposed scheme also addresses the issue of access control for new IoT devices with a short-term session key generation process. Security analysis is provided to show the efficacy of the proposed scheme against eavesdropping and replay attacks. A testbed based experiment is conducted to further demonstrate the RSS based value generation and distribution.
