The summary/abstract/whatever isn't really saying anything new. We've known we can make a brute force attack on WPA2 by temporarily de-authenticating a client for years, and yes, obviously it takes longer the longer the password is. I know they want to sell the article, but did they really need to keep the detail of what exactly do they improve upon also in secret? Are they really mentioning de-auth, spoofing and brute forcing as if they were anything new? Would someone that bought/knows someone who bought the article be kind enough to clarify on whether or not these guys actually came up with someone new or not, and if whatever they came up with is actually an important improvement from previous techniques?
