The IEEE has completed 802.11r, a standard that lets Wi-Fi devices roam quickly between wireless access points (WAP) and which improves the performance of VoIP on enterprise LANs. Traditionally, 801.11 devices can roam from one access point to another, but it takes about 100ms to re-associate, and several seconds to re-establish authenticated connections using 802.1x. Not good for time-critical apps like VoIP.According to InfoWorld, "the new standard, 802.11r, known as Fast Basic Service Set Transition, ...

My recent article on cloud computing has sparked quite a discussion about how realistic the scenario is, and how no one is going to use cloud computing as a standard way of working because it puts their privacy and security at risk. The truth is, everybody with a computer and internet access is already performing cloud computing. When in need for information, do you go to the library or do you use search engines and ...

We all know cryptography is hard. Time and time again we in the security community give advice that goes something like, “Unless you have an unbelievably good reason for developing your own cryptography, don’t!”. Even if you think you have an unbelievably good reason I would still take pause and make sure there is no other alternative. Nearly every aspect of cryptography is painstakingly difficult: developing new crypto primitives is hard, correctly implementing them is ...

Adi Shamir，图灵奖获得者，同时也是RSA公钥加密技术中的“S”，最近在Crypto 2008大会上介绍了一篇论文，声称一种新的密码分析技术能攻击范围广泛的加密方法。Shamir的论文还没有公开。 新的攻击可能影响到哈希函数（如MD5，SHA-256），流密码（如RC4），分组密码（如DES，Triple-DES，AES）。这种新的密码分析方法称为“cube attacks”，基于代数密码分析学。暂时还不会对上述列出加密方法有效，但它提供了一种新形式的攻击方法。 密码专家Bruce Schneier在博客上称，这种攻击不适用于任何分组密码。

Moving databases around is pretty common, as is moving databases between servers running different Editions of SQL Server, especially during a disaster recovery situation. You may not know this, but in SQL Server 2005, if you had partitioning anywhere in a database, you could only attach/restore that database using an Enterprise or Developer instance. I say 'you may not know this' because partitioning isn't really widely used (from what I can gather from talking to ...

Gmail recently rolled out a change to its settings, where now you can permanently turn on SSL encryption. Do it now—your personal data will thank you for it. Besides, it's going to get a lot easier to hack Gmail sessions very soon, because some guy is planning on releasing a hacking tool to the public in order to force Google to implement better security.

If you’re surfing on the free, public wi-fi at your local coffee shop, anyone with a modicum of computer skills will be able to sniff your traffic with this tool and take over your account. ...

To understand why serious encryption algorithms are so complex, and why it's so important to be careful with the critical secrets that make an encryption system work, it's useful to understand something about how people break encryption systems. The study of this is called cryptanalysis, and it's an amazingly fascinating field of applied mathematics. I'm going to be interspersing information about cryptanalysis with my cryptography posts. One thing to remember here is that we'll be ...

我们有太多的密码要记住，其中许多都是不安全的。Carleton大学的安全研究人员提出新的建议，让用户选择用数字内容如mp3，照片或视频去代替密码。因为每个文件都有一个独一无二的字符串哈希值，它可以如密码一般使用。虽然方法称不上完美，但非常值得一试。但是如果选择一个流传很广的图片，其安全性可能比常用的密码好不到哪里去。关于此设想的论文已在最新的Usenix大会上成为安全方面的热门话题。一个以此设想为基础的Firefox扩展程序也已发布(使用方法为：选择文字、图像或链接，单击右键，选择Get ObPwd from.....)。

The starting point talking about encryption is to understand what the point of it is; what it's supposed to do, what problems it's supposed to avoid. Encryption is fundamentally about communication: you've got two parties who want to communicate, but don't want anyone else to be able to listen in. They way that you do that is by sharing a secret. You use that secret to somehow modify the information that you're going to send, ...
