The hardware footprint for S-box specification in lightweight block cipher as appropriate to IoT and CPS information
security systems is presented in this paper. The S-box Boolean function in the lightweight block cipher is
defined using the Reed-Muller structure. A Rule Based–Common Sub-structure Sharing Optimization (RB-CSSO)
algorithm has been proposed towards improving the performance efficiency of Reed-Muller structure. This novel
hybrid RB-CSSO optimization mechanism first transforms the direct Positive Polarity Reed Muller (PPRM) S-box
representation into Mixed Polarity Reed-Muller (MPRM) S-box architecture using local rule based transformation.
Secondly, the Common Sub Term (CST) and Common Sub-expression (CSE) merging/elimination are employed
over the resulting MPRM structure. The combined rule-based transformation and the common sub-function
sharing demonstrate an overall reduction in area, delay and power of the Reed-Muller S-box structure. Both
the theoretical analysis and the experimental verification demonstrate reduction in area and delay of S-box. Post
synthesis results based on ASIC standard cell based implementations have been used to analyze area, delay and
power values across Process, Voltage and Temperature (PVT) corners for a wide range of operating conditions.
Extensive comparisons between direct PPRM and optimized MPRM implementations have been carried out. The
post layout simulations of S-box structures realized show the advantages of lower area-delay product, power-area
product and power-delay product. This work thus authenticates the application of proposed structure for lightweight,
resource constrained security systems. Industry standard full suite of Cadence® tools have been employed
in the simulations using 65 nm TCBN65GPLUS standard cells of TSMC technology library.
