Logic Locking Using Emerging 2T/3T Magnetic Tunnel Junctions for Hardware Security

With the advancement of beyond CMOS devices, a new approach to utilize inherent physics such emerging structures for various applications is great interest in recent research. Spintronics-based devices offer key advantages like ease fabrication with Si-substrate, non-volatile memory, low operational voltage, and non-linear device characteristics, which have shown potential several fields study. Hardware security one areas heavily relies on CMOS-based ICs, defense attack mechanism mostly based structures. This work explores 2T/3T magnetic tunnel junctions (MTJ) possible logic locking hardware systems. We demonstrate effect MTJ-based implement even presence process variations, its ability robustness imperfections has been evaluated using monte carlo simulations practical applications.
