Ironkey High Security Flash Drive: Use and Review
The Ironkey is a high security thumb drive designed to provide strong AES
encryption, tamper resistance and other security services. I'd seen the Ironkey
advertised quite a bit, and even read about its crypto systems and ruggedness,
but was left wondering about how it works in operation. Since the hardcore tech
side has been covered elsewhere, I'll concentrate on the Ironkey's usability and
features. Some of the topics covered will include: How is the drive mounted
without admin privileges in Windows? How is it mounted in Linux? How does the
"Self Destruct" feature work? What is Secure Sessions? How is the Ironkey better
than just using Truecrypt? I made this video to answer those sorts of questions
for myself and others. If you want more details on the crypto involved, see the
links section at the end of this video. The model I will be working with is the
1GB Ironkey Personal. I'll show its use and give my opinions on the device.

Slightly after I posted my video, Marc Luo from Ironkey sent me the following
email. It may clarify some of my points in the video:
I enjoyed your video. You definitely spent a lot of time playing around
with the product.
Couple of points:
· For linux you're for the most part correct. Depending on the
distribution, it may require root access in order to mount the cd-rom.
Some distributions like ubuntu mounts the drive automatically for a user
who does not have root. A partial way around this is to copy the
unlocker program onto the linux machine. If a user can execute the
unlocker program, then they do not need to mount the cd-rom or have root
· We are currently in process of changing the backup to hide the file
names. Not the first time we've heard this. J
· The keys that encrypt the IronKey never leave the crypto chip. When
the backup is done, new keys are generated and the backup is generated
and encrypted. In order to retrieve the backup an IronKey needs to start
the process (whether it's the original or a different one). In order to
decrypt the backup the password for the original IronKey is needed.
· As for cost, part of it is the dual SLC flash that is used. It's much
more expensive than MLC. SLC is by far higher quality. In addition the
crypto chip and quality of the drive itself is second to none. IronKey
is cost competitive or cheaper than drives that are classified in the
· Size is partially due to the dual SLC. IronKey wants the drive to be
of a certain size so that it looks and feels like a substantial product
that is difficult to lose.
· I believe in the pros should be the hardware encryption, which we
believe is far superior to software encryption (ie. Truecrypt). Also the
added features like the password manager and backup. There will be more
applications to come in the future that will be free updates.
Not really sure what you mean by non open source crypto. We use AES CBC
that has been certified FIPs level 2. We've had outside auditors look at
the source code to make sure it meets the highest standards.
The IronKey is on the expensive side if you're just looking for a usb
mass storage drive. It all depends on where your priorities are. If you
are security conscious, and looking for applications to protect your
presence on the web and protect sensitive data in a portable manner,
then I believe the IronKey is a small cost.
Thank you for your thorough video of the how-to's of the IronKey. You
did an outstanding job.
Let me know if you have any questions, and we're always looking for
suggestions on how to make the product better.
