With the emergence of Internet of Things (IoT), there is an urgent need to design energy-efficient and secure IoT devices. For example, IoT devices such as Radio Frequency Identification (RFID) tags and Wireless Sensor Nodes (WSN) employ AES cryptographic modules that are susceptible to Differential Power Analysis (DPA) attacks. With the scaling of technology, leakage power in the cryptographic devices increases, which increases the vulnerability to DPA attacks. This paper presents a novel FinFET based Secure Adiabatic Logic (FinSAL), that is energy-efficient and DPA-immune. The proposed adiabatic FinSAL is used to design logic gates such as buffers, XOR, and NAND. Further, the logic gates based on adiabatic FinSAL are used to implement a Positive Polarity Reed Muller (PPRM) architecture based S-box circuit. SPICE simulations at 12.5 MHz show that adiabatic FinSAL S-box circuit saves up to 84% of energy per cycle as compared to the conventional S-box circuit implemented using FinFET. Further, the security of adiabatic FinSAL S-box circuit has been evaluated by performing the DPA attack through SPICE simulations. We proved that the FinSAL S-box circuit is resistant to a DPA attack through a developed DPA attack flow applicable to SPICE simulations.
