Reducing the Gate Count of Bitslice DES

Matthew Kwan

Abstract: This paper describes various techniques to reduce the number of logic gates needed to implement the DES S-boxes in bitslice software. Using standard logic gates, an average of 56 gates per S-box was achieved, while an average of 51 was produced when non-standard gates were utilized. This is an improvement over the previous best result, which used an average of 61 non-standard gates.
