A 2-Mpixel CMOS Image Sensor with Device Authentication and Encryption Key Generation based on Physically Unclonable Function
Proceeding of the 2019 International Image Sensor Workshop, pp. 119-122, 2019
In Internet of Things (IoT) applications, security of sensor information is being discussed seriously. We have demonstrated a utilization of pixel offset variations in CMOS image sensors (CIS) for Physically Unclonable Function (PUF) to authenticate individual CIS device. In this paper, we present further application of CIS PUF to generate keys for cryptographic purposes, effectively binding the key to the hardware.
