We present a method for nding e cient instruction sequences for the Serpent S-boxes. Current implementations need many registers to store temporary variables, yet the common x86 processors only have 8 registers, of which even fewer are available for computations. The instructions are also destructive, replacing one input with the output. Alternative versions of the S-box instructions are presented, requiring only 5 registers and also utilizing parallelism. Speedup of C language implementations… CONTINUE READING
