SM4分组密码算法速度测试

 

 

 Intel(R) Xeon(R) CPU E5-2678 v3 @ 2.50GHz

 

一百万组，耗时约5.5秒

for (int i = 0; i < 1* 1000* 1000; i++)
{
cipher(data, text, key);
}

[root@localhost sm4]# g++ main.cpp
[root@localhost sm4]# time ./a.out

一千万组，耗时约50秒

for (int i = 0; i < 10* 1000* 1000; i++)
{
cipher(data, text, key);
}

[root@localhost sm4]# g++ main.cpp
[root@localhost sm4]# time ./a.out

速度约为3MB/s，感觉有点慢。。。。。。。
