Abstract

The Physically Unclonable Function (PUF) is a technique that generates unique device identifiers based on variations in the manufacturing process. The Internet of Things (IoT) has become widespread, and various kinds of devices are now available. Device authentication and key management are essential to provide a secure service to these devices. We can use the unforgeable identifier generated by the PUF as a key for encryption and authentication. However, the existing PUFs require a dedicated hardware or low-level software, i.e., driver. Thus, they are impractical to use on smartphones or IoT devices due to the severe limitations of production cost and power consumption. In this paper, we propose a sensor-based PUF that utilizes the accelerometer and gyroscope, which are widely available on smartphones and IoT devices. We implement the proposed PUF on a smartwatch and show that accelerometer-based PUF achieves good usability, extreme robustness, and a high entropy of 91.66 bits.
