LFSR based S-box for lightweight cryptographic implementation

This paper presents the hardware implementation of the Linear Feedback Shift Register (LFSR) based Substitution Box (S-Box) using ALTERA FPGA platform. Unlike the conventional designs, the proposed architecture is low in terms of its hardware cost; the total area and power consumptions. Hence, the new LFSR based S-box can be deployed in block ciphers to achieve lightweight cryptographic implementations.
