Then, I’d calculate B to the power of X, modulo M.

然后，我计算 B 的 X 次方，模 M。

John does the same, picking a secret exponent Y, and sending me B to the Y modulo M.

John 也这样做，选择一个秘密指数 Y，然后将 B 发送给 Y 模 M。

So now in the 21st century, Venice's ambitious plan to fight back against the ocean and geography is called the modulo sperimentale elettromeccanico or MOSE system.

所以在 21 世纪的今天，威尼斯发起了雄心勃勃的计划来对抗海洋和地理位置的劣势，即“摩西”计划。

If I tell you I raised 3 to some secret number, modulo 31, and got 7 as the remainder, you'd have to test a lot of exponents to know which one I picked.

如果我告诉你我将 3 加到某个秘密数字上，对 31 取模，然后得到 7 作为余数，你必须测试很多指数才能知道我选择了哪一个。

So, for example, if we wanted to calculate 3 to the 5th power, modulo 31, we would calculate 3 to the 5th, which is 243, then take the remainder when divided by 31, which is 26.

因此，例如，如果我们想计算 3 的 5 次方，模 31，我们将计算 3 的 5 次方，即 243，然后取余数除以 31，即 26。
