Key Generation Demonstration @ University of Liverpool

A WiFi-based key generation demonstration has been developed using WARP boards. A full key generation protocol has been implemented by the Python.

Overview

Our wireless communications are protected by the symmetric encryption, e.g., WiFi is secured by WPA2, which implements AES. However, the secure and efficient provision of keys for the symmetric encryption is very challenging for Internet of Things (IoT). We have been working on key generation from wireless channels and demonstrated this technique is very suitable for IoT.
