Abstract

Negative capacitance Field Effect Transistor (NCFET) is a promising CMOS compatible technology that exhibits relatively lower subthreshold swing (SS) and higher ON current at scaled VDD. This paper for the first time exploresthe design and security evaluation of NCFET based ultra- light weight PRESENT-80 cipher at 0.5V VDD. The NCFET based PRSESNT-80 cipher is analyzed by varying the ferroelectric thickness (tfe) of NCFET device. NCFET basedPRESENT-80 exhibit energy efficiency at tfe of 4nm. At 0.5V, NCFET based PRESENT-80 at tfe of 4nm exhibits 3.2× lower energy consumption compared to baseline 40nm CMOS design with 100MHz operating frequency. Apart from this, the security of NCFET based PRESENT-80 is evaluated against differential power analysis (DPA). With non-linear variation of dynamic power consumption profile, NCFET based PRESENT-80 is proved to be resilient against DPA compared to the baseline MOSFET design.
