Abstract:In recent years, Physical Unclonable Function (PUF) based hardware encryption has raised its significance in information security. Generally, a PUF is evaluated by three metrics: reliability, uniqueness, and uniformity. It is crucial for a PUF to have a good uniformity if it is used to generate cryptographic key. This paper focuses mainly on the Arbiter PUF and proposes a uniformity adjustment scheme for it. The main idea of this scheme is to add an adjustment module to the original circuit and construct an al… Show more
