Maybe it is mulish stupidity after all

Three weeks
ago I wrote about the U.S. government's efforts to keep the pending electronic
passport from being too secure. I still don't know for sure why the government
tried so hard to do this, but it's beginning to look like we should apply the
old adage "Never ascribe to malice what can be adequately explained by
stupidity."
Deputy
Assistant Secretary of State Frank Moss spoke on a panel about electronic
passports at the Conference on Computers, Freedom & Privacy in mid-April.
Security guru Bruce Schneier and Barry Steinhardt, director of the ACLU's
Freedom and Technology Program, joined him on the panel. You have to give Moss
credit for being willing to come to what was obviously going to be a den of
doubters.
Network World
sister publication PC World covered the event and provided audio recordings of
the talks. Schneier spoke first and focused on putting the issues in context
(zipped audio file).
Next came
Moss, who said the government had received more than 2,400 comments on the
electronic passport proposal (zipped audio file). He did not say, but it's my
guess that most of the comments did not much like the proposal. He said that
the passports, which are scheduled to be given to U.S. diplomats in August,
would not be implemented unless the government was sure that they would be
safe. (The government is doing a test drive of its own targets.) He said that
the government was looking at a number of options, including building a Faraday
cage into the passport to block scanning, but then he reiterated that the
passports could only be read by a scanner from a distance of 10 cm. He went on
to say: "The idea that you can walk down a hallway in a hotel and pick out
the Americans, is quite honestly, poppycock. The same thing goes for the bar in
Beirut. These things can only be read at very short distances." I expect
Moss is right about the hotel hallway, but expect he is incorrect about the
Beirut bar - something that he was about to find out.
Third up on
the panel was Steinhardt, who proceeded to give a live demonstration of
scanning a passport, which was outfitted with an RFID chip of the type
specified in the standard, at a distance of three feet. Moss finally seemed to
have paid attention when this was demonstrated in front of him because a few
days later, he told Wired News that the government was suddenly "taking a
very serious look" at the scanning issue. He didn't say what the result of
the serious look might be, but maybe the government will adopt the Basic Access
Control standard developed by the same people who developed the rest of the
standards for electronic passports. See the paper "Security and Privacy
Issues in E-passports" by researchers Ari Juels, David Molnar and David
Wagner for an analysis of this and other security issues about e-passports.
So maybe Moss
and company just needed to be shown they were wrong - in public - to get them
to listen. We will know soon if they learned any lasting lessons.
Disclaimer:
Lasting lessons are what places like Harvard are all about but we prefer to not
use public embarrassment to get a student's attention. Anyway, the above is my
hope, unshared (as far as I know) by the university.
