N2 - This paper presents a new light-weight key scheduler in AES using linear feedback shift register (LFSR). The conventional substitution-box (S-box) based key scheduler in the AES suffers from a considerable hardware resource consumption. To improve overall hardware efficiency, the proposed key scheduler exploits an LFSR based structure with XOR operation. The proposed design is implemented in a 32-nm CMOS technology, it is shown that our LFSR-based scheduler reduces area, delay, power, and energy by 53%, 56%, 12%, and 61%, respectively, compared to the S-box based counterpart.
