Abstract
This paper describes a design of AES(Advanced Encryption Standard)-based CCMP core for IEEE 802.1li wireless LAN security. To maximize its performance, two AES cores ate used, one is for counter mode for data confidentiality and the other is for CBC(Cipher Block Chaining) mode for authentication and data integrity. The S-box that requires the largest hardware in AES core is implemented using composite field arithmetic, and the gate count is reduced by about $20\%$ compared with conventional LUT(Lookup Table)-based design. The CCMP core designed in Verilog-HDL has 13,360 gates, and the estimated throughput is about 168 Mbps at 54-MHz clock frequency. The functionality of the CCMP core is verified by Excalibur SoC implementation.
