Re: Another Snake Oil Candidate

I'm a beta-tester for it, and while I can understand a small twitch  
when they talk about miltary and beyond military levels of  
security, it is very cool.


It has hardware encryption and will erase itself if there are too  
many password failures. I consider that an issue, personally, but it  
appeals to people. The reason I consider it an issue is that I have  
had to use a brain-dead-simple password I'm not going to forget  
because if I get cute and need to try a number of things, poof, I'm  
dead.


Yeah, it's using AES CBC mode, but that's a good deal better than a  
lot of encrypted drives that are using ECB.


It also has their own little suite of Mozilla plus Tor and Privoxy  
for browsing and they've set it up so that you can run that on  
another computer from the drive.


It's not bad at all. My only real complaint is that it requires Windows.

The IronKey appears to provide decent security while it is NOT  
plugged into a PC. But as soon as you plug it in and you have to  
enter a password to unlock it, the security level quickly drops. This  
would be the case even if they supported Mac OS or *nix.


As I stated in my response to Jerry Leichter, in my opinion, their  
marketing department is selling snake oil.

 As I commented to Bruce, see what Kahn says about it:  But the work,
 while containing some cipher systems, mainly defends the occultism of
 Trithemius.

  Sure, that's what the *ciphertext* says  g

I think there is a difference between a product that is susceptible to
an attack and the pure distilled 100% natural snake oil, as we usually
define it.

Indeed, the encrypted USB token is susceptible to sniffing of the
password on the PC where it is entered. But in my opinion this is not
the type of flaw that snake oils the product, because:

1. It's a limitation that also exists in the state of the art products
of its type. That is, nobody could ever do better (I think).
2. It therefore does not reflect complete lack of understanding on the
developer's side...

So perhaps it's not pure snake oil but just a product with an attack
vector; most products have at least one.

Actually, this product is (almost) the first one that I saw which
actually bothers to deal with the brute-force attack vector, which does
exist in many other similar products. So it's not perfect, and I would
certainly not bet my life on it, probably not even my life's data, but
it's reasonable.

Hagai.
