In this paper, the design principle of the Arbiter Physical Unclonable Function (APUF) based on the arbiter is studied, the existing problems are analyzed, and the problem of its delay asymmetry is studied. This paper proposes two methods that can change the uniformity of PUF, by changing the delay on each path to make the uniformity of PUF closer to 50%. The improvement of PUF uniformity can greatly increase the security of PUF, making information storage more vulnerable to external attacks.
