In this paper we are interested in algebraic immunity of several well known highly-nonlinear vectorial Boolean functions (or S-boxes), designed for block and stream ciphers. Unfortunately, ciphers that use such S-boxes may still be vulnerable to so called " algebraic attacks " proposed recently by Courtois, Pieprzyk, Meier, Armknecht, et al. These attacks(More)
