<nettime> (fwd) IPv6 standard to include unique identifier in all packets |
<http://www.techweb.com/se/directlink.cgi?INW19991004S0052> Where's All The Outrage About The IPv6 Privacy Threat? Bill Frezza What happens when companies such as Intel or Microsoft are found to have embedded unique identifiers in their hardware or software that pose potential privacy problems for Internet users? As we know from experience with both the Pentium III Serial Number flap and the Microsoft Win98 Registration Wizard brouhaha, professional privacy advocates sound the alarm, the press launches a feeding frenzy, Wall Street shudders and the alleged corporate miscreants are flogged into backing off. Now, what happens when the Internet Engineering Task Force does the same thing, specifying an addressing structure in its next-generation Internet protocol, IPv6, such that every packet can be traced back to each user's unique network interface card ID? Apparently, nothing. It's a conundrum that makes one wonder about the motives of the reigning Internet digerati, who spend much of their time assuring us that they are protecting our interests as they quietly arrogate power in the new world order. IPv6 was initially proposed to solve the "problem" that IPv4 has with running out of addresses. You would think that the 32-bit address field of IPv4, supporting more than 4 billion unique addresses, would be sufficient to last quite some time. Unfortunately, the cabal that controlled the disposition of these addresses had a habit of handing out large blocks to their friends, who parlayed these into start-ups with multibillion-dollar market caps. Hence, the "shortage." IPv6, on the other hand, has 128 bits of address space, enough to provide a billion-billion addresses for each square meter of the earth's surface. How one could ever route that many addresses is an interesting question, but at least IPv6 will never run out. As you might expect, the address field is so huge that the IETF didn't know how to assign it. So, in a move to get buy-in from established industry standards bodies, the right-most 64 bits were designated to contain EUI-64 format information. This is used by the IEEE to assign Ethernet addresses, which are normally not transmitted outside a user's LAN. Included in EUI-64 are two interesting pieces of information: the registered manufacturer of your NIC card and your 48-bit Ethernet address. Surprise! Every packet you send out onto the public Internet using IPv6 has your fingerprints on it. And unlike your IP address under IPv4, which you can change, this address is embedded in your hardware. Permanently. The spooks and weirdos in Washington, ever eager to empower the surveillance state as they fight a rear-guard action against strong encryption, must be thrilled with such a gift. They appear so thrilled that the Institute for Information Sciences, heavily funded by the Defense Department, is writing a reference stack for IPv6 that it is quietly hoping to slip into Windows 2000. Where are the professional privacy advocates on this issue? Let's start with the Electronic Frontier Foundation (EFF), champions of freedom in cyberspace and cofounders of the TRUSTe initiative. TRUSTe's mission is to build "trust and confidence in the Internet" with a branded, online "trustmark" assuring users that their privacy will be respected. Go search EFF's site and see if you can find a single word about IPv6 and its privacy problems. The EFF's silence is matched by a similar lack of concern from the Center for Democracy and Technology and the Electronic Privacy Information Center, both of which are usually the first to man the barricades when Big Brother comes knocking. Could it be that this unusual averting of the collective gaze is just an embarrassing attempt to avoid airing the family's dirty laundry? With all the interlocking boards, directorates, subcommittees and associations that keep the digerati in sync, it's hard to know where responsibility for this snafu begins and ends. A new advocacy group called the IPv6 Forum, headed by honorary chairman Vint Cerf, is leading the charge for adoption, and the usual alphabet soup of geek groups appears to be falling into line. This may be the reason the press hasn't shown much interest. It's a lot more fun to kick Intel and Microsoft than to rail at the folk heroes credited with creating the Internet. It looks like the geeks screwed up this time, though. I hope they have the wisdom to fix things before it's too late. Bill Frezza is a general partner at Adams Capital Management.
