Abstract
This paper presents an improved impossible differential attack on the block cipher SMS4 which is used in WAPI (the Chinese WLAN national standard). Combining with some new observations, this paper can filter out the wrong keys more efficiently, and present an impossible differential attack on 17-round SMS4, which updates the best known impossible differential attacks on reduced SMS4.
