Due to the exponential growth of wireless and mobile applications, security has become a paramount design aspect. New techniques have been proposed for replacing the broken Wired Equivalent Privacy (WEP) protocol, which arguably is the most widely security tool used up to now in wireless environments. Under this scenario, AES in CCM (Counter with CBC-MAC) mode has been included in the IEEE 802.11i wireless standard as a promising alternative to the compromised WEP protocol. In this contribution, we present an FPGA implementation of the CCM mode of operation using AES as its block cipher. Our design achieves a throughput of 1.05 Gbits/Sec with reasonable area requirements.
