MV3: A new word based stream cipher using rapid mixing and revolving buffers [PDF]

open access: yes, 2006
MV3 is a new word based stream cipher for encrypting long streams of data. A direct adaptation of a byte based cipher such as RC4 into a 32- or 64-bit word version will obviously need vast amounts of memory. This scaling issue necessitates a look for new
