A Lightweight PUF-Based Authentication Protocol Using Secret Pattern Recognition for Constrained IoT Devices

PUFs, or physical unclonable functions, are hardware security primitives that can offer lightweight solutions for constrained devices through challenge-response authentication protocols. However, the PUF-based have been presented often lack features such as mutual message encryption, which could be vital many applications. Other protocols suffer from vulnerabilities to denial of service attacks make them impractical use. This work introduces a protocol uses secret pattern recognition and authenticated exchange on Internet Things. The utilizes several techniques introduce nonlinearity, it employ any strong PUF circuit soft model generated. process requires simple bitwise operations along with true random number generator (TRNG). By avoiding use cryptographic hash protocol's nature is preserved. proposed against modeling tested showcase its resilience. Similar investigated found some essential features.
