In this paper, the authors propose the implementation of high speed crypto system for secured communication that is hard to crack and improve the safety of data communicated. S-box that uses the combinational logic is introduced in this paper to improving the system computing speed instead of using ROM based LUTs. In this paper, the authors synthesize both the S-boxes and compare the performance. Comparison shows that S-box using the combinational logic is faster. It is very efficient in terms of memory consumption. Using this method of encryption the data could be protected effectively.
