Gadget Steals Encryption Keys

Here’s how it works: the PITA consists of a bunch of off-the-shelf parts and it runs on four AA batteries. Using an antenna that can read electromagnetic waves emitted by computer processors from up to 19 inches away, the device can swipe RSA and ElGamal data and decrypt it. Stolen data is then stored locally on the device’s microSD card, or the PITA can transmit data over Wi-Fi to the attacker’s computer.

The cost of the radio device has been estimated at $300 / €270 and it can be built with readily available components: a Rikomagic controller, a piece of wire acting as an antenna and a FUNcube software defined radio (SDR).


The FUNcube Dongle Pro+: LF to L band software-defined radio


No drivers required! Device drivers are already included in your operating system – Windows, Linux or Mac OSX, 32 or 64 bit.
* The guaranteed coverage of the FUNcube Dongle Pro+ is from 150kHz to 1.9GHz, and there is a gap in coverage between 240MHz and 420MHz.

Installing the very latest on Ubuntu Linux

You'll find recent packages of bluefish in the Bluefish PPA maintained by Klaus Vormweg. Follow the instructions given there to add this repository. Then bluefish can be updated to its latest release:
sudo apt-get update
sudo apt-get upgrade
Please note, that the http://debian.wgdd.de repository has become obsolete. See below, how to clean your system.

Removing obsolete debian.wgdd.de entries from sources.list

The http://debian.wgdd.de/ repository no longer provides packages of bluefish. The above steps make the following entries to either /etc/apt/sources.list or /etc/apt/sources.list.d/debian.wgdd.de_*.list or any other file in /etc/apt/sources.list.d/ obsolete. You can safely remove any references to the http://debian.wgdd.de repository, that may look like these:
deb     http://debian.wgdd.de/debian wheezy main contrib non-free
deb-src http://debian.wgdd.de/debian wheezy main contrib non-free
deb     http://debian.wgdd.de/debian stable main contrib non-free
deb-src http://debian.wgdd.de/debian stable main contrib non-free

deb-src http://debian.wgdd.de/ubuntu UBUNTU_VERSION_HERE main restricted universe multiverse 
and update your system:
sudo apt-get update
sudo apt-get upgrade
Also the wgdd-archive-keyring package then is obsolete together with the repository keyring. If you have the package installed, do:
sudo apt-get autoremove --purge wgdd-archive-keyring
... or if you only had the key:
sudo apt-key del E394D996

Installing Bluefish on openSUSE

Bluefish is available in the main repository. Launch YaST and search for "bluefish" to find and select the appropriate package to install.
This process is also automated through 1-Click-Install on the openSUSE Build Service: https://software.opensuse.org/package/bluefish

Installing Bluefish on AltLinux

Installing Bluefish on Slackware

Installing Bluefish on Mac OS X

Download the latest version installer from http://www.bennewitz.com/bluefish/stable/binaries/macosx/, open it and drag the bluefish icon onto Applications.
In Mavericks there is a system setting called Gatekeeper that only allows you to install packages from Apple-identified developers. Bluefish is not distributed through the Apple app store, so you will have to workaround that setting.
Use the contextual menu (e.g. secondary-click button), and you'll see a menu with "Open" in it. This will present you with a dialogue box, asking you for permission to run the software. You will only be asked this the first time.
Alternatively, the Gatekeeper setting can be disabled. For information, see: https://kb.wisc.edu/helpdesk/page.php?id=25443 or http://support.apple.com/kb/ht5290

Download any language dictionaries you wish to be able to install: http://www.muleslow.net/files/aspell/lang/
Place the files in a new directory named 'redist' in the same directory as the Bluefish installer. e.x.
Bluefish\
Bluefish\Bluefish-2.2.7-setup.exe
Bluefish\redist\gtk2-runtime-2.24.8-2011-12-03-ash.exe
Bluefish\redist\aspell6-en-7.1-0.tbz2
The installer will fall back on downloading the files if they are not found in the redist folder, or if the checksum of the local copy is invalid.

I was looking at the isotope's table and noticed that one of Lead's isotopes can actually turn into stable gold through this mechanism :
Pb82197  81197Tl  80197Hg  79197Au

I know (or at least guess) that such a process must be awfully ineffective. Still, I was wondering :
  • How could we get a great quantity of Pb82197 ?
  • How long would it take for it to turn into gold ? Can that be accelerated ?
  • Once most of it has been turned into gold, how can we extract the gold ? (there are still remaining Pb,Tl,Hg molecules)
  • What would be the yield of the process ? How much money would it approximately cost compared to how much we win in gold ?

Interesting idea, but it has already been done, and not cheaply - read on.
How could we get a great quantity of Pb82197 ?
There would be two problems with getting a large amount of Pb82197. First, the parent nuclide of Pb82197 is Bi83197 which is unstable and has a half-life of only 9.33 minutes - so you can't get a large quantity of Pb82197's precursor to begin with. Second, once Pb82197 is formed, it has a half-life of 8.1 minutes, so it transmutes quickly to Tl81197.
How long would it take for it to turn into gold?
Pb82197 half-life = 8.1 minutes
Tl81197 half-life = 2.84 hours
Hg80197 half-life = 64.14 hours
After 10 half-lives, ca. 0.1% of the starting material will be left
(12)10=0.0009766
The last step is the slowest by far, so after about 641.4 hours (26.73 days), you should have something around 99.9% pure gold.
Can that be accelerated?
Unlike chemical reactions that can heated, catalyzed, etc., this type of nuclear transformation keeps a set schedule.
Once most of it has been turned into gold, how can we extract the gold ? (there are still remaining Pb,Tl,Hg molecules)
As noted above, you can get whatever purity you desire, just wait.
What would be the yield of the process?
It would be high for the 3 nuclear transformations you listed. Each of the elements you listed decays directly and only to the daughter isotope you've shown. However, as noted above, you can't start with Pb82197, you generate it from Bi83197, the decay of which adds some impurity along with lead. And then since the bismuth isotope is not long-lived you'd probably start with its precursor, and so on until you find something that has a long enough life that you could assemble a reasonable quantity.
Back around 1980 Glenn Seaborg actually transmuted bismuth to gold, but only a few thousand atoms (see this reference also).
How much money would it approximately cost compared to how much we win in gold?
The Wikipedia article I referenced directly above notes, "the expense far exceeds any gain." There are other ways (fission and fusion) to produce gold, but at least with the methods available today, the cost would be astronomical.

Can't Pb82197 be obtained by sending particles on normal lead ? - Also, what would the obtained gold look like ? (as it forms particle by particle, would it be some kind of dust provided we have enough molecules ?) – Hippalectryon Aug 23 '14 at 17:14

Anything is possible, but... The stable isotopes of lead are 204, 206, 207 and 208, you'd have to knock a lot of protons and neutrons out to get down to 197. – ron Aug 23 '14 at 17:18

Don't knock off protons otherwise you wouldn't have lead anymore. – s0rce Aug 24 '14 at 4:37
One thing Ron didn't cover is the side effects of all that decay. All that short-half-life stuff will be rather radioactive, to the point where you might not survive to see the results. It's also possible that if you get enough together to be profitable that it will simply vaporize itself. The stable gold should eventually condense so as long as you contain the vapor it might work. Or you'll have a very pretty gold-lined flask.

Shame! Knock a proton off of lead and it turns into thallium. But as that's the point of the exercise just bump off two more and we're done
