VXorPUF: A Vedic Principles - Based Hybrid XOR Arbiter PUF for Robust Security in IoMT

The Internet of Medical Things (IoMT) is playing a pivotal role in the healthcare sector by allowing faster and more informed hospital care, personalized treatment, and medical solutions. Several authentication systems are used to safeguard the data and authenticate the devices, but some of them are inefficient and some of them have some limitations. A very effective and trustworthy solution for resource-constrained medical devices is provided by Physical Unclonable Functions (PUF) - based identity and authentication systems. This paper proposes VXorPUF, a Vedic Principles - Based Hybrid XOR Arbiter PUF. Modeling attacks were performed on the proposed architecture and an accuracy of 49.80% was achieved. Uniqueness, Reliability and Randomness were the figures of merit used to evaluate PUF. A further study was evaluated the uniformity of (m,n,p)-OAN-XOR-PUF, and a result of 43.75% was found, which is close to the ideal value of arbitrary PUF response.
