摘要：

SMS4 is a 128-bit block cipher used in the WAPI standard for protecting data packets in WLAN. In this paper, various S-box circuit architectures were evaluated firstly and the twisted BDD with m=4 was proved as the fastest one. A fast SMS4 cipher VLSI implementation was completed based on the twisted BDD S-box architecture, and achieved over 200MHz and 100MHz maximal frequency on SMIC 0.18 mu m and Chartered 0.35 mu m CMOS technology respectively.
