| 摘 要： | 高级加密标准AES是Linux系统中安全网络协议采用的主流的加解密算法。该文通过分析AES加解密算法，结合龙芯平台的体系结构特征，提出基于多媒体指令扩展（SIMD技术）优化AES性能的方法。优化前后的安全文件传输协议Sftp（AES加解密）数据传输结果表明，龙芯SIMD技术优化AES算法减少了加解密时间，有效地提高了Sftp的网络传输速率。

| Abstract: | The advanced encryption standard is the mainstream encryption algorithm in the security network protocol used in Linux system. Through analysis of AES encryption algorithm,with the architecture characteristics of the Loongson platform,the method for performance optimization of AES based on the expansion of multimedia instructions (SIMD technology) is proposed. Before and after optimization,the results of data transmission using security file transfer protocol Sftp (AES encryption) shows that the Loongson SI... |
