艳照门引来一系列商业机会，高登，天涯，贴吧的流量飙升，baidu，google，p2p也大行其道，各类加密软件也引起广大网友的关注，今天从Gerg处看到一个新鲜的技术方案，关于破解硬盘加密的新技术，难不成老外也受了艳照门的影响？开个玩笑，我们来看一下他具体的实现技术。

通常我们认为，电脑关机后所有内存的内容都清空了，安全专家Ed Felten 发了一篇文章Cold Boot Attacks on Disk Encryption告诉大家事实并不是这样的，即使电源关闭，内存中的内容依然能保留数秒到数分钟，如果对内存用液态氮实施冷冻，内容甚至能保留数个小时之久。有了这个发现后，Ed Felten 和他的八个同事运用这种方法破解了3款流行的硬盘加密产品，
“We show that disk encryption, the standard approach to protecting sensitive data on laptops, can be defeated by relatively simple methods. We demonstrate our methods by using them to defeat three popular disk encryption products: BitLocker, which comes with Windows Vista; FileVault, which comes with MacOS X; and dm-crypt, which is used with Linux.

这篇文章还介绍了如果破解的原理，当然这么挑战人们常识的文章也吸引了不少读者回帖，俗话说天下没有不透风的墙，看来再保险的加密也有破解的办法啊。
