Veda-PUF: A PUF based on Vedic Principles for Robust Lightweight Security for IoT

This paper proposes a new controlled Physical Unclonable Function (PUF), Veda-PUF, which uses an algorithm for pre-processing and post-processing the input and output of PUF to increase the security of the keys generated in Internet-of-Things (IoT) devices. The key size of the PUF can be increased using the proposed protocol without compromising the integrity of the keys generated. The uniqueness of the generated keys was 50 % and the reliability of the keys generated is 99.9 % which are close to the ideal values. The proposed control algorithm also increases the uniqueness and reliability of the PUF keys after processing. This increases the number of PUF keys that can be used for various applications.
