在这里恭喜 Diffie 和 Hellman 两人，前两天刚凭借这个密钥交换算法获得了 2015 年度的图灵奖。 首先，对于 $y equiv g x quad ( bmod p)$ 这个等式中，知道 g、x、p 是很容易计算出 y 来的。 但是知道 y、g、p 的情况下，算出 x 来却十分困难。 首先，通信的双方 Alice 和 Bob 分别选择一个随机数 $r A$ 和 $r B$，然后分别计算他们自己的. M A = g {r A} quad ( bmod p)$. M B = g {r B} quad ( bmod p)$. 然后 Alice 和 Bob 分别把自己算出来的 $m A$ 和 $m B$ 发送给对方。 所以 Eve 是知道 $m A$ 和 $m B$ 的。 但是由于反方向计算十分困难，所以 Eve 无法反推出 $r A$ 和 $r B$。 Alice 和 Bob 分别接收到对方的 $m B$ 和 $m A$ 后。 S = (g {r A}) {r B} quad ( bmod p) $. S = (g {r B}) {r A} quad ( bmod p) $. 假设某条加密过的数...

Toying With Cryptography: Crib Dragging. Cryptograhpy has become very topical in the UK over the last few years, what with the UK government wanting to do nasty things to it. It also happens to be one of my weakest areas. I don’t know a whole lot about how it works and I probably should. Because of this, I’m reading crypto101.io. It’s a book written by lvh. And made available for free. It all begins with an ideal: one-time pad. The XOR operation is often denoted with a (caret) and works like this:. The a...

Intriguing matters, engaging content, interesting stuff. Summary Critique of the New PCA Agenda. A friend asked me to summarise my critique of the new PCA Agenda. What follows is a very brief summary of my critique based on many weeks of Sabbath School discussions ranging across the broad sweep of the proposed agenda. It is by no means exhaustive, but is intended to be brief and summary. Shall we resolve to discipline those who fail to support bringing Syrian refugees to the US? The point here is that as...
