Physical Unclonable Functions (PUFs) are a set of emerging technologies to deal with cloning, Intellectual Property(IP) protection, and security against reverse engineering schemes to restrict the over production of semiconductor chips. Delaybased PUFs represent an inviting option due to minimal space circuitry over conventional type arbiter PUF. This paperpresents a novel transmission gate based arbiter PUF for authentication of the electronic hardware systems. These PUFs havebeen widely used as security primitives for device authentication and identification. By measuring the statistical parametersusing Monte Carlo analysis we demonstrated that the proposed design significantly enhances the performance of the arbiterPUF. Our arbiter PUF produced 48.5% of uniqueness for 64 bit challenge pair, and their reliability was demonstrated acrossdifferent environmental variations.
