With the proliferation of connected internet of things (IoT) devices, trusted communications between such de-vices is an increasing concern. While researchers have spent significant resources to address this challenge, most solutions impose significant energy, delay, and complexity overhead on energy-constrained IoT devices. In this paper, we first provide an overview of some of the techniques used to incorporate security and trust features into IoT devices. Then, we propose and demonstrate an innovative encryption approach for wireless IoT communications which is low-energy, low-complexity, and low-latency. The proposed cryptography integrates the encryption into the RF front-end of a wireless transceiver and is energy-efficient, making it suitable for real-time and energy-limited IoT connectivity applications.
