摘　　要：为提高Camellia加密算法的灵活性,提出一种新的Camellia加密算法实现方法。通过改进Camellia算法的实现架构,在资源占用和数据吞吐率两个方面做到平衡折中。采用优化的紧凑型结构,在复用架构的同时,适当添加寄存以提高数据吞吐率。仿真结果表明,该方法资源占用比全流水结构减少70%,与紧凑型结构方法相比,数据吞吐率提升4倍。In order to improve the flexibility of Camellia encryption algorithm,a method of implementing Camellia encryption algorithm based on Field Programmable Gate Array（ FPGA） is proposed. By improving the implementation architecture of the Camellia algorithm,a balance can be achieved in terms of resource consumption and data throughput rate. With the optimized compact structure,the addition of hosting improves the data throughput while reusing the architecture. Simulation results show that the resource consumption of this method is reduced by 70% compared with the full-flow structure, and the data throughput rate is improved by 4 time compared with the full-compact type.
