Calculating Cryptographic Degree of an S-Box

Prasanna Raghaw Mishra

Abstract: In this paper we propose an efficient technique to compute algebraic degree of an S-box (minimum of algebraic degrees of its component functions). Using our technique we have calculated algebraic degree of a $26\times 64$ S-box.
