Silicon based Physical Unclonable Function (PUF) is a popular security primitive for mitigating such hardware security vulnerabilities. In the recent years, Quasi-adiabatic logic based physical unclonable function (QUALPUF) was proposed. The QUALPUF has ultra low-power consumption, hence it suitable to implement in low-power portable electronic devices. In this paper, we present a new adiabatic PUF which is based on QUALPUF. With improving the circuit topology using a small number of the power supply, the proposed PUF have become compact in size compared with the conventional adiabatic PUF. Through the simulation results, we show that the proposed adiabatic PUF provides higher reliability and lower energy consumption.
