Abstract
The Internet of Things (IoT) is considered as the key enabling technology for smart services. Security and privacy are particularly open challenges for IoT applications due to the widespread use of commodity devices. This work introduces two hardware-based lightweight security mechanisms to ensure sensed data trustworthiness (i.e., sensed data protection and sensor node protection) and usage privacy of the sensors (i.e., privacy-aware reporting of the sensed data) for centralized and decentralized IoT applications. Physically unclonable functions (PUF) form the basis of both proposed mechanisms. To demonstrate the feasibility of our PUF-based approach, we have implemented and evaluated PUFs on three platforms (Atmel 8-bit MCU, ARM Cortex M4 32 bit MCU, and Zynq7010 SoC) with varying complexities. We have also implemented our trusted sensing and privacy-aware reporting scheme (for…
