我正在嘗試使用ECDH/ECDSA來確保我的運輸。我將micro-ECC移植到mbed作爲測試，因爲我不熟悉裝配，所有裝配優化都被禁用。這裏是my project。ECC生成的密鑰保持不變是否正確？
的運行代碼打印信息到控制檯如下：

然而，結果保持相同，包括隨機數，公共/私人密鑰和共享密鑰。我實際上添加了一個random_test（）來檢查它的RNG。
#if defined(RNG_TEST)
void randtest()
{
uint8_t buf[16];
pc.printf("randtest():\r\n");
for(int i=0; i<16; i++){
buf[i] = rand();
pc.printf("%02X",buf[i]);
}
}
#endif
而且它的隨機數總是在變化。
