Abstract :
We propose a compatible design of CCMP and OCB AES cipher for wireless LAN. IEEE 802.11i defines the AES-based cipher system, which is operated in CCMP mode or in OCB mode. Our design supports both modes of operation. The implemented OCB and CCMP feature 40 Mbps and 243 Mbps throughput, respectively, at 50 MHz frequency, and are targeted to a Xilinx Vertex FPGA device.
