Abstract

The Priority Arbiter-based Physical Unclonable Function (PA-PUF) is a one-way function implemented in hardware, where output or response bits, corresponding to a given set of challenge bits, are influenced by the device-specific parameters. An n-length PA-PUF can be represented as an n-variable Boolean function. The research we conducted demonstrates the exploration of Boolean functions obtained by implementing a PA-PUF construction with randomly selected delay parameters. We observe that the set of Boolean functions generated from PA-PUF is significantly larger than the set of Boolean functions generated from classical Arbiter-based PUF. Further, we look into the bias estimation of the response bit generated from PA-PUF towards the impact of changing specific bits in the challenge input. Finally, we perform a comparative analysis on PA-PUF to study its cryptographic properties and a detailed analysis of the machine learning attacks.
