Dragon: A Fast Word Based Stream Cipher

This paper presents Dragon, a new stream cipher constructed using a single word based non-linear feedback shift register and a nonlinear 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
