摘　　要：针对Rijndael算法特点,结合雷达网数据通信需要,提出一种适于FPGA实现的改进的快速方案.本方案采用轮内流水线结构和密钥并行处理,ECB操作模式,并且可支持128 bit、192 bit、256 bit 3种密钥长度.仿真结果表明该设计相比其它一些设计具有更高性能.According to the characteristic of Rijndael algorithm and the requirement for radar network data communication, an ameliorated celerity Rijndael algorithm suitable to FPGA implementation was presented. An inner-pipeline and parallel key, ECB model, which supports 128 bit, 192 bit, 256 bit three keys, was adopted. Simulation results show that this design has better performance than any other FPGA implementation of Rijndael.
