VoIP products could face export crackdown

(continued from previous page)

It wasn't immediately clear what percentage of enterprise-level networking products could be affected by the export regulations, and members of the Commerce advisory committee were inaccessible for the remainder of the day because they entered a so-called closed session (click for PDF) to discuss classified material. One committee member did indicate, however, that the exact number of permitted conversations would be discussed during a closed session.

As microprocessor speeds and privacy worries have increased, manufacturers are gluing encryption into the routers used for VoIP communications. Cisco's 2800 series offers the Secure Real-time Transport Protocol, a standard that supports an encryption protocol believed to be one of the world's most secure. Patton Electronics, a Gaithersburg, Md.-based manufacturer, in February began selling a VoIP router that, like Cisco, uses the well-regarded AES algorithm.

Export controls' troubled past
This is hardly the first time that export control laws have yielded unexpected results. In 2000, Japan's government slapped export controls on the PlayStation 2, saying it could be used for military purposes.

In the past, U.S. export controls have targeted processors as slow as a 450 MHz Pentium. As recently as 2004, federal rules have required computer sellers to get a license to export a computer using a Pentium 3 processor running at 650MHz.

But encryption restrictions on software were what caused the loudest outcry. Because encryption code could be exported in printed form but not exported on a floppy disk or through the Internet, it led to bizarre twists like a band of cypherpunks legally exporting a book of PGP source code and then scanning it in from a computer in Europe. It also sparked a "munitions" T-shirt on which was printed a functional encryption algorithm written in Perl.

Eventually, after facing at least three federal lawsuits claiming First Amendment violations, strident opposition from the U.S. business community and the reality of programmers abroad churning out high-quality code, the Clinton administration relented in September 1999. Even after the Sept. 11, 2001, terrorist attacks, Sen. Judd Gregg, a New Hampshire Republican, was the only politician to talk seriously about cracking down on encryption use.

Complicating the regulatory picture today is VoIP's flexible nature: Unlike a circuit-switched network that allocates a circuit for each phone call, Internet telephony travels as a stream of bits.

Henry Brandt of IBM, co-chairman of the Commerce committee, said that as phone networks move increasingly toward packet-switching, "the control becomes meaningless... because nowhere along the chain will you ever know it's VoIP."

When data travel over the Internet, packets take multiple different routes that make talking about "channels" a bit awkward, said Don McGill, director of enterprise support systems for CNET Networks, publisher of News.com. "It's not quite the same kind of environment, so it's hard to put it in terms of channels per se," McGill said.

Angelo, the committee member from NetIQ, suggested that "where IPsec lives is where the (export) control would be applied." IPsec, which stands for Internet Protocol security, uses encryption to authenticate messages and scramble them as well. It's often used with virtual private networks, or VPNs.

This has to be some low attack by the Ma Bel Companies
Does goverment need that much control,

Well i just need to thank the cold war and tell them to get off. This is becomming rediculous finding a 10 year old law to prevent the distribution of equipment thus putting a major tack in the road for VoIP adoption. Maybe they will outlaw SSH.
