Summary:In the field of hardware security, Physically Unclonable Functions (PUFs) have emerged as a critical technology for ensuring the uniqueness and integrity of electronic devices [1]. One of the main distinctions lies in the challenge-response behavior [2]: weak PUFs have a small number of challenge-response pairs (CRPs) and are usually employed for secure key storage or device identification; strong PUFs are more resistant to modeling attacks due to the vast number of CRPs and are used in challenge-response authentication systems. One of the key parameters that measures the PUF security level is the entropy. \vert \mathrm{n} our study, we used as a measure for entropy the minimum size of a random digital memory that could effectively reproduce the PUF behavior.
