Optimization Design of AES Encryption Algorithm Based on FPGA

摘要: 现如今随着网络技术的不断发展，网络设备的数据处理速度变得越来越快，与此同时，信息安全相关的问题也逐渐显现了出来。针对高速网络信息的报文加密的优化问题，提出了一种AES加密的优化方法。通过对明文的识别、分组加密和替换，有效地隐藏了明文序列，提高了网络报文的保密性和安全性。经测试，优化后的AES加密算法可以正确有效地完成高速网络报文的加解密部分的工作。

Abstract: Nowadays, with the continuous development of network technology, the data processing speed of network equipment is becoming faster and faster. At the same time, the problems related to information security have gradually emerged. Aiming at the optimization problem of packet encryption in high-speed network, an optimization method of AES encryption is proposed. Plaintext identification, packet encryption and replacement can effectively hide plaintext sequence and improve the confidentiality and security of network messages. After testing, the optimized AES encryption algorithm can correctly and effectively complete the encryption and decryption of high-speed network packets.
