Query: pHGen: A pH-Based Key Generation Mechanism Using ISFETs   Digital keys are a fundamental component of many hardware- and software-based
security mechanisms. However, digital keys are limited to binary values and
easily exploitable when stored in standard memories. In this paper, based on
emerging technologies, we introduce pHGen, a potential-of-hydrogen (pH)-based
key generation mechanism that leverages chemical reactions in the form of a
potential change in ion-sensitive field-effect transistors (ISFETs). The
threshold voltage of ISFETs is manipulated corresponding to a known pH buffer
solution (key) in which the transistors are immersed. To read the chemical
information effectively via ISFETs, we designed a readout circuit for stable
operation and detection of voltage thresholds. To demonstrate the applicability
of the proposed key generation, we utilize pHGen for logic locking -- a
hardware integrity protection scheme. The proposed key-generation method breaks
the limits of binary values and provides the first steps toward the utilization
of multi-valued voltage thresholds of ISFETs controlled by chemical
information. The pHGen approach is expected to be a turning point for using
more sophisticated bio-based analog keys for securing next-generation
electronics.
