Physical Unclonable Functions (PUF) for IoT Devices

PUF – Physical Unclonable Functions

from historical banking and telecommunication applications to electronic passports, electronic IDs, anti-counterfeiting devices, smartgrid applications, and more. The security requirements for most of these applications are crucial and evolving. In addition, more and more sophisticated attacks are being developed every day. As a result, design of Smart Card ICs is a growing challenge. This pape...

Physical Unclonable Functions for IoT Security

SD-PUF: Spliced Digital Physical Unclonable Function

Digital circuit physical unclonable function (PUF) have been attracting attentions for the merits of resilience to the environmental and operational variations that analog PUFs suffer from. Existing state-ofthe-art digital circuit PUFs, however, are either hybrid of analog-digital circuits which are still under the shadow of vulnerability, or impractical for real-world applications. In this wor...

6.2 Physical Unclonable Functions

11:00 6.2.1 EFFICIENT ATTACKS ON ROBUST RING OSCILLATOR PUF WITH ENHANCED CHALLENGE-RESPONSE SET (Paper/SoftConf ID: 699) Speakers: Phuong Ha Nguyen, Durga Prasad Sahoo, Rajat Subhra Chakraborty and Debdeep Mukhopadhyay, Indian Institute of Technology Kharagpur, IN Abstract Physically Unclonable Function (PUF) circuits are an important class of hardware security primitives that promise a paradi...

Physical Unclonable Function (PUF) Based Random Number Generator

Physical Unclonable Functions (PUFs) are widely used to generate random Numbers. In this paper we propose a new architecture in which an Arbiter Based PUF has been employed as a nonlinear function in Nonlinear Feedback Shift Register (NFSR) to generate true random numbers. The rate of producing the output bit streams is 10 million bits per second. The proposed RNG is able to pass all NIST tests...
