Physically unclonable function using initial waveform of ring oscillators on 65 nm CMOS technology
This work addresses hardware security needs for integrated circuits by offering a more efficient PUF design, though it appears incremental as it builds on conventional RO-PUFs.
The paper tackled the challenge of reducing resource usage and time for generating IDs in silicon physically unclonable functions (PUFs) by proposing a ring oscillator (RO)-PUF using initial waveforms on 65 nm CMOS technology, resulting in a greatly reduced number of ROs and ID generation within a couple of system clocks.
A silicon physically unclonable function (PUF) using ring oscillators (ROs) has the advantage of easy application in both an application specific integrated circuit (ASIC) and a field-programmable gate array (FPGA). Here, we provide a RO-PUF using the initial waveform of the ROs based on 65 nm CMOS technology. Compared with the conventional RO-PUF, the number of ROs is greatly reduced and the time needed to generate an ID is within a couple of system clocks.
