In Bletchley Park in England, a center was set up to break Enigma. Machines called turing bombes were constructed to break the cipher. In the end, the Allies were able to intercept and decrypt Enigma transmissions, and great effort was expended to ensure that the Germans were unaware that their messages were being read—and more importantly—understood. Cryptography Explained More recently, in the last 10 years, a lot of public attention has focused on cryptography. Several critical events elicited this attention, but two are particularly worth noting.
That’s like the last six pixels in an electronic image. ” It was all Greek to Sam, but the news that the guy might be on to something was welcome. Sam himself had drawn a blank looking through the colonel’s papers. The computer guy started explaining what he was doing. “I’m using this program called S-Tools, Cryptography Explained and a few other programs I’m writing on the fly, to extract hidden data. And there’s definitely stuff here. ” Sam could hear the frustration in the guy’s voice: They were so near, but without a key, the hidden information would stay hidden.
Unfortunately, with crypto, there is no definitive way to prove that an algorithm is secure. In fact, the only way to determine that a crypto algorithm is probably secure is to have a bunch of really smart people try to break it. If, after five or more years, they cannot break it, you can assume that it is probably secure. There could still be a vulnerability that they missed, but the chances are slim. That is why new algorithms are not considered to be secure for at least five to eight years. In doing an analysis of an algorithm there is no mathematical principle that guarantees that you tested for every possible vulnerability.
