| Abstract(in English) | Physical unclonable function (PUF), which provides an intrinsic and chip-specific response, attracts increasing attention in the field of security. Random telegraph noise (RTN) is time-dependent threshold-voltage variation of metal-oxide-semiconductor transistors. The time constant of the RTN-induced threshold voltage variation varies greatly between transistors, which is suitable to enhance the uniqueness of PUF. In this paper, a novel PUF structure is proposed, which uses frequency variations of ring oscillators due to RTN to generate unique bit responses of each chip. Numerical experiments using synthetic RTN signals prove that the proposed PUF achieves greater uniqueness than existing PUFs. |
