The proposed concept is to mask intermediate data passing through internal registers L1 and L2 in the non-linear function part, and then unmask the data at the outputs of L2 and FSR-B.  We evaluate the performance of the proposed method through ASIC implementations on a 90 nm CMOS technology. Compared with the unprotected design, the performance overheads in circuit area and delay are increased at most 1.5 and 2.5 times, respectively.
