Abstract
  In this paper, we present four low-cost substitution boxes (S-boxes) including two 4-bit S-boxes called $S_1$ and $S_2$ and two 8-bit S-boxes called $SB_1$ and $SB_2$, which are suitable for the development of lightweight block ciphers. The 8-bit $SB_1$ S-box is constructed based on four 4-bit S-boxes, ...  Read More
