We present a method for finding efficient instruction sequences for the Serpent S-boxes. Current implementations need many registers to store temporary variables, yet the common ...
Abstract. Byte pair encoding (BPE) is a simple universal text compression scheme. Decompression is very fast and requires small work space. Moreover, it is easy to decompress an ar...
In this paper, we suggest a block-restricted sifting strategy which is based on the restriction of Rudell's sifting to certain blocks of variables. The application of this st...
