Radio
Frequency Identification (RFID) Systems
FACT OR FICTION
The recent
panic that resulted from the media hype blitz regarding a team of individuals capturing a transponder code was, at the
least, extremely over exaggerated and misinterpreted to a greater degree by the media, which was subsequently passed on to
the members of the insurance companies Special Investigations units, law enforcement personnel and to the public.
FACT:
The team of individuals was actually composed of a team of graduate students and a scientist from the John Hopkins
University in Baltimore Maryland and from the RSA Laboratories. The tests were limited only to a Texas Instrument
transponder, one of five companies that use transponder technology in today's vehicles.
FACT:
The team admits in their reports that transponder technology in today's vehicles has reduced
auto theft as much as 90%.
FACT:
The team also sites Texas Instruments in their report as stating that after they were advised of the test results "they
have recieved no reports due to the vulnerability" of the transponder system.
FACT: The team bought a commercial microchip costing less
then $200.00 and programmed it to find the KEY for a gasoline purchase tag. They then linked 16 such chips
together and cracked the key code in about 15 minutes.
FACT: The team did not consist of a group of auto thieves, or for that matter even sophisticated
well educated auto thieves, but did consist of three graduate students, one faculty member and two industrial scientists
all of whom specialize in the field of data security and applied cryptography.
FACT: Based on the information provided by the media, relative
to auto applications, the " CRACK" affected only a single chip currently used only on the Ford Focus and Escape
and the Ford produced Mazda Tribute. WHEN WAS THE LAST TIME YOU HAVE HAD ONE OF THESE VEHICLE'S REPORTED STOLEN.
FACT: The team did not
physically defeat the steering column ignition locking system, which also must be defeated. They would have
had to use a properly cut key.
FACT:
Does the JHU/RSA teams study findings mean that it is easy to steal gasoline and automobiles equipped with the transponder
technology? NO! What the researchers have shown is that these types of crimes are easier than widely believed.
It must be understood that the experts in the field of data security and applied cryptography conducted these tests under
ideal laboratory conditions, with apparently no time restraints as well as an unlimited amount of resources.
The
tests were undoubtedly funded with an unspecified amount of funds available to the team.
Although the team has
so far demonstrated an ability to scan a victims device at a range of only a few inches, the team still believes that
this poses a real practical threat in public spaces, as it is not difficult to brush up in such close proximity to a potential
victim. The team is still testing the device with a greater distance than only a few inches.
To date the
team has not been able to "CRACK" other transponder systems, especially the "ROLLING CODE" system of the
BMW, Mercedes Benz, and others that use this technology.
Texas Instrument expresses a confidence in the security
of RFID systems and have stated the following when asked: What should an existing Speed Pass user or car owner
with an RFID vehicle Immobilizer do to protect themselves?" "RFID-enabled products like any other car key
or payment device needs to be protected from being lost or stolen. There are no additional protections necessary".
In addition, if you observe a person with a laptop in your close proximity, do not panic, as they only may be
doing there homework or surfing the World Wide Web.
It took this group and a handful of
computers three months of full time work to crack this one chip.
