Wireless Security

Wireless transmissions are vulnerable against eavesdropping due to the broadcasting nature. Thus, it is often required to consider secure transmissions using encryption. While existing ciphers can be used as in wired transmissions, a group of new approaches based on physical layer security (PLS) has been studied in order to exploit wireless channels. For the Internet of Things (IoT) and wireless sensor networks (WSN), PLS based secure transmission schemes become good candidates in order to provide small devices of limiting computing power with lightweight security. The list of our related publications is as follows.
