What Clinton's proposal will mean to the Rest of the World
by R.Tait＠bnr.co.uk 18 Apr '93

18 Apr '93

Cypherpunkers, Having just digested the press release, and the subsequent followups on sci.crypt and on here, I am beginning to wonder what ramifications this might have in other countries, specifically the "Superpowers". Surely setting such a precedent in his own country will spark off a flurry of activity in places such as the UK, Germany, France et al, so that they are not "left behind", so-to-speak? To be quite honest, I can't see the English government taking such radical steps about secure telecommunications, quite simply, because BT have such a lacsidasical [sp?] approach to new and emerging technologies. Take for instance, IDSN. Their philosophy of marketing and "selling" ISDN is laughable - I once read a newspaper article which related a tale of a Corporation who wanted to learn if ISDN could be useful to it's business practices, and it seems that BT just kept jostling them between department (Dept X: "Phone Dept Y", Dept Y: "Phone Dept X" etc). Can anyone really see that the US government (or whoever) will completely outlaw all strong data encryption? This violates the basic human right of free communications/privacy.

AT&T Press Release on Clipper
by Dave Banisar 18 Apr '93

18 Apr '93

Here's AT&T's announcement on the Clipper. AT&T TO INCORPORATE NEW 'CLIPPER' CHIP INTO SECURE COMMUNICATIONS PRODUCT LINE GREENSBORO, N.C., April 16 AT&T (NYSE: T) said today it is moving to improve the security and privacy of telephone communications by incorporating a just-announced new U.S. government technology for voice encryption into its secure communications product line. AT&T will use the Clipper chip, announced today by President Clinton as a new technology for voice encryption, in all of its secure telephone products except those specially designed for government classified customers. The Commerce Department has announced a six-month timetable for the final certification of Clipper. "AT&T is pleased to be the first company to publicly commit to adoption of the Clipper chip," said Ed Hickey, AT&T vice president, Secure Communications Systems. "We believe it will give our customers far greater protection in defeating hackers or eavesdroppers attempting to intercept a call. "And now all commercially available AT&T voice encryption products will be compatible with each other, a major step forward in bringing secure communications capabilities to the business community." In standardizing AT&T voice encryption products on the Clipper chip, AT&T will include the algorithm in the Telephone Security Device as well as in the Secure Voice/Data Terminal. The AT&T Telephone Security Device is a compact, lightweight unit that brings advance encryption technology to conventional land-line and cellular telephones. It provides a powerful, convenient and reliable way to protect the most sensitive telephone conversations. The device works with a conventional land-line or transportable/mobile cellular phone. It turns the phone's signal into a digital stream of encrypted information that is decrypted by a Telephone Security Device attached to the phone at the receiving end of the call. The AT&T Telephone Security Device connects easily to desk telephones or tranportable or mobile phones. It weighs 1.5 pounds and is 7 inches long, 4.5 inches wide and 1.5 inches high. And it's as easy to use as it is portable. The AT&T Secure Voice/Data Terminals are desktop telephones that provide encryption for both telephone calls and data transmissions. These AT&T secure communications products use an enhanced voice encryption technique that provides very high voice quality. This technology allows calls placed with these products to approach the voice quality of normal calls. To further enhance interoperability, AT&T will consider licensing to other manufacturers its enabling technologies for interoperability. Interoperability of encryption devices requires common technology beyond the use of a common encryption algorithm, specifically common methods of digital voice encoding and signaling. AT&T has already performed integration tests with Clipper chips manufactured by the government's supplier, Mykotronx Inc., of Torrence, Calif., and is preparing to integrate the chip into the manufacturing of its secure products. AT&T's Clipper-equipped telephone security devices will be available to customers by the end of the second quarter. The federal government intends to adopt the Clipper chip as the standard for voice encryption to help protect proprietary information, protect the privacy of personal phone conversations and prevent unauthorized release of data transmitted electonically. At the same time, use of the Clipper chip will preserve the ability of federal, state and local law enforcement agencies to intercept lawfully the phone conversations of criminals. "Adoption of Clipper will support both the government's efforts to protect the public and the public's right to privacy," Hickey said. AT&T Secure Communication Systems provides products to protect voice, data, fax, cellular and video communications. It also engineers and integrates secure communications applications. Its customers include the governments of the United States and other nations as well as major corporations around the world. AT&T Secure Communications Systems is headquartered in Greensboro.

Mitch on the Clipper Mailing list

I had asked Mitch to repost any communications that have gone over this list. He has. I appreciate his willing to clear up this issue. As I have stated before, I believe him, that NIST simply created this list of people they wanted to be in direct contact with. /harry a conscious being, Mitchell Kapor wrote: > From mkapor(a)eff.org Sun Apr 18 00:58:00 1993 > Message-Id: <199304181257.AA06031(a)eff.org> > Date: Sun, 18 Apr 1993 08:58:00 -0800 > To: habs(a)Panix.Com > From: Mitchell Kapor <mkapor(a)eff.org> > Subject: Re: The mysterious mailing list > > I received the statement of the Press Secretary and the public fact sheet > from Ed Roback.

The gov't makes sense ;-)
by baumbach＠atmel.com 18 Apr '93

18 Apr '93

My eyes have been opened, after reading the White House press release. Privacy can only be allowed if the users don't break any laws. If through accident or other means we find that someone who is using privacy has broken the law, we need to be able to discover what has been hidden by privacy in the past to see if other laws were broken. It is for the greater good! Let's have the gov't set a good example for us too follow. I want all government employees and anyone they have spoken to, to be recorded always. The tapes will be encrypted and stored safely in the hands of all losing presidential candidates. If a citizen has probable cause to believe that a person in gov't has broken the law, then, with proper safeguards, he will be given copies of the appropriate tapes and the keys, to get to the bottom of this. If through accident or other means we find that someone who is using privacy has broken the law, we need to be able to discover what has been hidden by privacy in the past to see if other laws were broken. It is for the greater good. Peter Baumbach baumbach(a)atmel.com

The mysterious mailing list (fwd)
by Harry Shapiro 18 Apr '93

18 Apr '93

There have been reports about a mailing list set-up at NIST that had a number of people on it including Mitch Kapor. The list is named "clipper" and it was through that list that part of the Wire Tap Chip announcement came. I asked Mitch directly, what is involvement with that list was; I asked him if he was involved with the development of the Wire Tap Chip. Below is is reply. I believe him. /harry a conscious being, Mitchell Kapor wrote: > From mkapor(a)eff.org Wed Apr 17 23:11:38 1993 > Message-Id: <199304181111.AA05559(a)eff.org> > Date: Sun, 18 Apr 1993 07:11:38 -0800 > To: habs(a)Panix.Com > From: Mitchell Kapor <mkapor(a)eff.org> > Subject: The mysterious mailing list > > I believe the list in the question is an informational list set up at NIST. > My name was placed on it.
