Physical Unclonable Function(PUF) is lightweight hardware that provides affordable security for electronic devices and systems which can eliminate the use of the conventional cryptographic system which uses large area and storage. Among the several models, Bi-stable Ring PUF(BR-PUF) is considered as a secure and efficient PUF model since it has no mathematical model still found. In this thesis, we proposed a modified design called a hybrid model of BR-PUF and a Chaotic network to improve the BR-PUF resilience against machine learning attacks. We experimented with the current modification XOR technique to analyze the uniqueness, reliability and resource consumption. The proposed PUF was implemented on Xilinx Artix 7 FPGA and the PUF metrics were captured and compared with the results of XOR-ed based PUF integration techniques. The lightweight PUF model was achieved with 16% resource reduction when compared to XOR-ed BR PUF with no compromise in PUF quality.
