摘要
旨在对AES加密算法进行研究,并采用Nios II CPU的SOPC集成实现方式,基于FPGA设计出了具有加解密功能的、密钥可配置的、资源利用和吞吐量都十分理想的SOPC加密系统。系统轮变换通过状态机进行控制,采用加密内部和解密外部的密钥扩展方式,大大提高了系统的实现速度。
The AES encryption algorithm is researched in this paper, which is designed using the Nios II CPU on SOPC integrated implementations. It includes encryption and decryption functions, configurable key. And resource utilization and throughput are ideal on FPGA design. System round transformation is controlled by the state machine. The encryption and decryption extende internal external key, greatly improving the speed of system.
