Recent years have seen the rapid growing market of smart phones. At the same time, pirated, knockoff or refurnished phones have also flooded into the worldwide market and inflicted great loss on the mobile phone industry. Existing anti-counterfeiting, authentification and identification methods, which rely on the verification of the IDs stored in the phone(More)
In the applications of biometric authentication and video surveillance, the image sensor is expected to provide certain degree of trust and resiliency. This paper presents a new low-cost CMOS image sensor based physical unclonable function (PUF) targeting a variety of security, privacy and trusted protocols that involves image sensor as a trusted entity.(More)
One main problem encountered in the FPGA implementation of Arbiter based Physical Unclonable Function (A-PUF) is the response instability caused by the metastability of delay flip-flop. This paper presents a new multi-arbiter approach to extract more entropy to extend the number of response bits to a single challenge. New multi-arbiter schemes based on the(More)
