检查vps对于AES(AEAD)算法的支持和性能[0]

Posted on 2023年11月14日2025年5月6日 by

上图显示vps支持aes算法

上图显示vps对于aes-256-gcm算法的执行效率

aes算法是现代x86计算机上cpu支持的指令集,采用硬件解码,效率较软件实现解码cpu占用低,对于ARM架构的处理器到V8才开始支持AES,并且性能较差,明显没有优化。

上述算法对于加密数据通讯有较强的应用意义。

 

补充说明:

1)Intel(R) Xeon(R) Gold 6348 CPU @ 2.60GHz——chacha20算法的效率

openssl speed -evp chacha20-poly1306

2)Intel(R) Xeon(R) Gold 6348 CPU @ 2.60GHz——aes-256-gcm算法的效率

openssl speed -evp aes-256-gcm

3)rockchip-armv8——chacha20

4)rockchip-armv8——aes256

 

认识的提高:

1)就解码性能而言,x86处理器再aes解码上性能远超chacha20

2)在arm处理器上,aes性能不如chacha20

欢迎回来
