Abstract
Terminal devices that perform machine-to-machine (M2M) communication may autonomously perform password authentication by autonomously generating a personal identity number (PIN) value, which is not exposed externally, using a physical unclonable function (PUF). A terminal apparatus that performs M2M communication may include a PUF embedded in the terminal apparatus to generate an authentication key for password authentication associated with the terminal apparatus, and an authentication unit to perform the password authentication associated with the terminal apparatus using the authentication key generated by the PUF.
