Implementation of Data Encryption with AES-CCM in WiMAX based on FPGA
Yun Wei-guo · Communications technology · 2008
Based on the original security mechanisms of IEEE802.16D version,the data encryption with AES in CCM mode is introduced into IEEE802.16e to solve the problem of original security mechanisms lacking anti-replay protection and encryption algorithm itself’s insecurity.This paper analyzes the data encryption with AES in CCM mode defined in the standard of IEEE 802.16e,implements synchronous design with RTL Verilog descriptions.The design is evaluated by Static Timing Analyzer,Functional Simulation,Timing Simulation and Power analysis,and also debugged on Virtex-4 XC4VFX12 FF668.The implementation results indicates that the design occupies less resources and has a higher throughout.
