Abstract

This paper presents Dragon, a new stream cipher constructed using a single word based non-linear feedback shift register and a non-linear filter function with memory. Dragon uses a variable length key and initialisation vector of 128 or 256 bits, and produces 64 bits of keystream per iteration. At the heart of Dragon are two highly optimised 8 × 32 s-boxes. Dragon uses simple operations on 32-bit words to provide a high degree of efficiency in a wide variety of environments, making it highly competitive when compared with other word based stream ciphers. The components of Dragon are designed to resist all known attacks.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
