Quantum Computation article

David P. DiVincenzo from the IBM Research Division has written an article in the 13th October issue of SCIENCE magazine (vol. 270, pg. 255-261) entitled "Quantum Computation". The article is nicely divide into subsections: - Building blocks of quantum logic - Quantum circuits - Peter Shor's prime factorization - The decoherence problem - Outlook >From the outlook section "It is evident from this survey of the current state of the art in quantum experimental physics that the construction of quantum computers is presently in the most rudimentary stage, and that to even think about a procedure like Shor factorization, which might require millions of operations on thousands of qubits, might be absurdly premature." If that is the good news for Cypherpunks, then the great news is the following. ". . even a few bits of quantum computation will be very useful in performing so-called Bell measurements, which could be used to implement quantum teleportation, in which an unknown quantum state can be trasmitted to a remote location. At perhaps the 10-qubit level, a quantum computer becomes capable of performing Schumacher's quantum coding, which would be of interest in the implementation of efficient quantum cryptography. And at perhaps the 100-qubit level, a quantum computer becomes an efficient repeater for a noisy (that is partially decohered) quantum cryptographic link." It looks like the advantages of quantum computing accrue to Alice and Bob, long before it becomes useful to Eve and Mallet. A must read for aficianados of "alternative computing".

In a Federal Register notice which outlines "capacity requirements" for surveillance of the nation's communications infrastructure, the FBI is claiming that compliance with CALEA requires that telephone companies and other service providers in some regions of the country build in enough surveillance capacity so that *one percent* of all phone lines could be *simultaneously* wiretapped, calls isolated, and forwarded to the FBI. This would permit wiretapping at a level at least a thousand time greater than currently occurs in the United States. This level of surveillance is also far in excess of what Congress intended when it enacted the CALEA. The rule, if adopted, will lead to a radical change in the surveillance capabilities of the government. The methodology used to determine capacity requirements is also deeply flawed. Wiretapping reports, as required by law, have always been based on actual taps authorized, actual conversations intercepted, and actual lines surveilled. These numbers are reported annually by the Administrative Office of the U.S. Courts. The Bureau's proposed rule attempts to shift from the analytic approach required by current wiretap law to one that is based on percentages of total communications activity. It is similar (in purpose and magnitude) to a government agency that had received an annual appropriation of $12 m to argue by regulation that it was now entitled to 1% of the federal budget (roughly $18 b). EPIC has filed a Freedom of Information Act request seeking all documents relating to the development of this proposed rule. WHAT YOU CAN DO: (a) Submit comments to the FBI. Object to the "percentage approach" to wiretap capacity. Urge the FBI to follow the current measurement of wiretapping, as reported annually by the Administrative Office of the U.S. Courts, which considers the actual number of wiretaps authorized. If you are a telephone customer, ask the FBI to address the privacy risks of unauthorized, illegal, or excessive wire surveillance. Comments should be submitted in triplicate to the Telecommunications Industry Liaison Unit (TILU), Federal Bureau of Investigation, P.O. Box 220450, Chantilly, VA 22022-0450. For further information, contact TILU at (800) 551-0336. Refer to your question as a "capacity notice" inquiry. ** Comments must be received by November 15, 1995.** (b) If you represent or work for a telecommunications company, equipment manufacturer, or service provider, assess carefully the cost and liability that this proposed federal regulation may impose on your company and the risk that it may expose your customers to illegal wiretapping. If you are interested in challenging the final FBI rule, contact EPIC and send us a copy of your comments. We are prepared to assist individuals and companies with a legal challenge. The FBI Federal Register notice (October 16, 1995, Volume 60, Number 199, Pages 53643 - 53646) is available at: http://www.epic.org/wiretap/calea_notice_10_95.txt EPIC will soon post a copy of its FOIA request and its comments on the regulation to implement a national wiretap plan. ======================================================================= [2] Illegal Bugging by U.S. Agencies Continues ======================================================================= Reports of illegal wiretapping by U.S. agencies are on the rise. Last week Japanese officials expressed concern over a report of CIA spying during automotive trade talks earlier this year, and said they would ask the United States to investigate, according to an October 16 Reuters report. "This is certainly not a very pleasant matter," said Trade Minister Ryutaro Hashimoto. Ichiro Fujisaki, political minister at the Japanese embassy "expressed the Japanese government's concern that should the report be true, it could hurt our national sentiment and U.S.-Japanese friendship and mutual trust." The New York Times reported earlier that the Central Intelligence Agency conducted electronic surveillance in the course of preparing reports for American negotiators prior to an accord reached in June. The Times also reported that U.S. Trade Representative Mickey Kantor "was regularly supplied with information gathered about the Japanese negotiation position by the CIA's Tokyo station and the National Security Agency, which operates electronic eavesdropping equipment." (NYT, Oct. 14, 1995). The Washington Post confirmed the incident and noted that the "eavesdropping reflected the U.S. intelligence community's increasing involvement in economic and commercial information gathering since the end of the Cold War." The illegal wiretapping report follows an incident earlier this year when French officials charged that the United States intelligence agencies engaged in clandestine monitoring of trade negotiations. Meanwhile, the President of Estonia was forced to resign following news that he had engaged in secret wiretapping of political opponents. According to the New York Times, residents of Estonia wondered whether the days of Soviet police agents spying on citizens had returned. Newly chosen President Lennart Mei called the scandal "a crisis of democracy." He said, "We must ask ourselves: Does power belong to the people if surveillance equipment is in the hands of others?" (NYT, Oct. 18) Estonia is the most recent country to see its government fall after public disclosure of illegal wiretapping. In the last few years, Greece and France have replaced political leaders because of wiretapping scandals. ======================================================================= [3] Status of Wiretap Funding ======================================================================= In 1995 the Communications Assistance for Law Enforcement Act authorized the expenditure of $500,000,000 over four years to reimburse companies to design wiretap-ready communications technologies. But opposition to the "Digital Telephony" proposal forced the FBI and the White House to find a creative way to fund the unpopular program. Now the Administration is proposing that the $500 M be gathered from a special fund which authorizes the surcharge of 40 percent on all civil fines levied by the United States after October 1, 1995, excluding fines levied by the Internal Revenue Service. [The specific legislative provision may be found in Title IV of the Counterterrorism Bill, HR 1710 (Civil Monetary Penalty Surcharges and Telecommunications Carrier Compliance Payments). The terrorism bill is now under consideration by Congress and will be the subject of an upcoming EPIC Alert]. But even the "slush" fund may not generate enough money to reimburse companies to design wiretap capabilities, which some industry experts estimate may run in excess of $2 billion. The House appropriations bill for the Department of Justice sets aside only $50 M for the Telephone Carrier Compliance program. The U.S. Telephone Association earlier recommended that the government follow traditional funding methods for the program rather than the slush fund approach taken in the Counter-terrorism bill. The benefits of such a budget, said the USTA, include the fact that "it brings the process into the sunshine, making government surveillance expenditures an issue for public scrutiny." (USTA Wiretap Workshop, May 1995). The Office of Technology Assessment, before its demise, also prepared a useful overview of the bill and discussed the funding issues -- "Electronic Surveillance in a Digital Age" (OTA 1995). Further information about wiretapping is available at the EPIC web page: http://www.epic.org/privacy/wiretap/ ======================================================================= [4] Court Rules Against Hi-tech Spy Toys ======================================================================= In a case that illustrates that the protections provided by the Fourth Amendment against the intrusiveness of modern technologies are still very much alive, the U.S. Court of Appeals for the 10th Circuit ruled on October 4 that police must obtain a warrant before using Forward Looking Infrared Radar (FLIR) devices to examine private residences. FLIR measures heat differentials on surfaces of as little as 0.5 degrees Celsius to determine activities inside homes. Police use FLIR devices to scan neighborhoods an detect houses that emanate heat which may be caused by "grow" lamps. In U.S. v. Cusumano, No 94-8056, No 94-8057, Oct. 4, 1995, the court ruled that new technologies do not eliminate the normal expectation of privacy that individuals have in their homes. Echoing the words of Justice Brandeis' opinion in a 1928 wiretap case, the court said: the Defendants need not have anticipated and guarded against every investigative tool in the government's arsenal. To hold otherwise would leave the privacy of the home at the mercy of the government's ability to exploit technological advances: the government could always argue that an individual's failure (or inability) to ward off the incursions of the latest scientific innovation forfeits the protection of the Fourth Amendment ... [T]he government would allow the privacy of the home to hinge upon the outcome of a technological race of measure/counter-measure between the average citizen and the government -- a race, we expect, that the people will surely lose. Other courts have split on this question. Recently, the Washington State Supreme Court ruled that a warrant is required before FLIR can be used (State v. Young, 867 P.2d 593 (Wash. 1994), while several other federal appeals courts have ruled that the heat is "waste" not protected by the Fourth Amendment. The 10th Circuit opinion rejected the waste argument "because the interpretation of that data allows the government to monitor those domestic activities that generate a significant amount of heat. It . . . strips the sanctuary of the home of one vital dimension of its security: the 'right to be let alone' from the arbitrary and discretionary monitoring of our actions by government officials." ======================================================================= [5] NTIA to Release Privacy "Policy" ======================================================================= The National Telecommunications and Information Administration is expected to release today (October 23) a white paper entitled "Privacy and the NII: Safeguarding Telecommunications-Related Personal Information." In an agency press release, NTIA administrator Larry Irving said, "We hope to contribute to the effort of addressing the public's concerns regarding the protection of their personal information." NTIA says the paper will focus on "privacy concerns associated with an individual's subscription to or use of a telecommunications or information service." But if the final NTIA report is at all similar to a privacy policy discussed by an NTIA official at a conference earlier this month in Brehmen, Germany there is little that will reassure the public about this policy. Ignoring mounting evidence that voluntary codes have failed and that new technologies of privacy should be promoted, the NTIA recommends a "be careful out there" strategy, in effect saying that it is better to post warning signs along the information highway than to make the road safer to travel. The NTIA proposal specifically recommends the "contract" approach to privacy that was rejected by European officials earlier this year as an inadequate safeguard for consumers using advanced communications services. NTIA officials, and other members of this Administration, have claimed that with changing technology it is too difficult to legislative effectively. But a different group of public officials, facing a similar challenge 20 years ago did not make such excuses. *Records, Computers, and the Rights of Citizens* (1973) was a ground-breaking report that spoke clearly of the need to protect citizens rights, led to passage of the Privacy Act of 1974, and established firmly the importance of Fair Information Practices. NTIA's report, like the other privacy "policies" of this administration, will occupy no similar place in history. The spirit of Clipper has infused this government. Copies of the report are available from NTIA at 202/482-3999 and will soon be posted at the EPIC web site with a complete critique. EPIC has also prepared a detailed review of an earlier administration privacy code: http://www.epic.org/privacy/internet/epic_nii_privacy.txt ======================================================================= [6] Privacy Success -- Marketry Drops Plan to Sell Net Data ======================================================================= In a notable victory for consumer privacy and on-line activism, a Bellevue, Washington company has backed off plans to sell personal information gathered from the Internet following reports in the Washington Post and a call to action in the EPIC Alert. Marketry President Norm Swent announced last week "Marketry's resignation as manager of the email Internet Interest Selector list." However, Marketry was not the compiler of the data. Another agent could still be found. Washington Post reporter John Schwartz broke the Marketry story in the paper's Business section following news of the proposal in the industry trade publication The Friday Report. The Marketry data was to be gathered from newsgroup posts, website visits, and chat room comments. ======================================================================= [7] ACLU Civil Liberties Alert / Privacy Rights Clearinghouse ======================================================================= An excellent civil liberties on-line newsletter is the ACLU Cyber-Liberties Update/ To subscribe to the ACLU Cyber-Liberties Update, send an e-mail message to infoaclu(a)aclu.org with "subscribe ACLU" in the subject line of your message.

FV -- What we have learned
by Nathaniel Borenstein 17 Dec '03

17 Dec '03

Please excuse the cross-posting, I'll keep it short. With my colleagues at First Virtual, I have recently completed what we intend to be the definitive statement about what FV has learned from a full year of processing payments over the Internet. This is not intended as a puff piece, but a serious academic-style overview. We're hoping it will prove to be a valuable resource for anyone trying to process payments on the net, even those who disagree with some aspects of FV's approach. The paper will be presented next week at the "Frontiers in Electronic Commerce" conference in Austin. In Postscript, it's a 14 page paper with a nearly 30 page appendix, so it doesn't *have* to be a long paper to read unless you want it to be. :-) Plain text and postscript versions are available on the net by anonymous ftp: ftp://ftp.fv.com/pub/nsb/fv-austin.{txt,ps} -------- Nathaniel S.

COMMUNITY CONNEXION TO OFFER REWARD FOR REVEALING HOLES IN ECASH
by sameer 17 Dec '03

17 Dec '03

For Immediate Release Contact: Sameer Parekh sameer(a)c2.org 510-601-9777 (pager: 510-321-1014) COMMUNITY CONNEXION TO OFFER REWARD FOR REVEALING HOLES IN ECASH October 23, 1995 - Community ConneXion, an internet privacy provider in Berkeley, California, announced the extension of its existing "Hack" contests to the electronic cash system announced today by Digicash bv and Mark Twain Bank. "The ecash deployment an important step towards making internet commerce more than just a curiosity," said Sameer Parekh, President of Community ConneXion. The contest is meant, as with the other "Hack" promotions being run by Community ConneXion, to encourage the examination of the security of the ecash system so as to reveal holes before they are exploited by a criminal element. Community ConneXion hopes that the inquiry being done into the security of these products results in a secure infrastructure for the new paradigms provided by internet commerce. "All internet commerce systems thus far released have been based in old, out-of-date, insecure technology, such as credit cards. DigiCash is the first revolutionary system which can change the way we do business," said Parekh. "If the move to internet commerce does not radically improve the way people do business, then we have not taken full advantage of the potential inherent in the technology." Details regarding the Hack DigiCash promotion are available on Community ConneXion's webserver at http://www.c2.org/hackecash/. Contest submissions should be sent to hackecash(a)c2.org. Community ConneXion is the premier internet privacy ISP. They offer anonymous accounts, remailers, and psuedonym servers, in addition to the standard ISP fare of webspace and dialup IP access. Information is available from http://www.c2.org/ or from sending email to info(a)c2.org. Ecash, DigiCash, Cyberbucks, and Mark Twain Bank are trademarks of their respective owners.

ANNOUNCEMENT: Digest Version Changes Hosts
by Alan B. Clegg 17 Dec '03

17 Dec '03

The digest version [cypherpunks-d] of the cypherpunks mailing list has been moved to a faster host. Previously it was under the care of majordomo(a)gateway.com, but it has been moved to the care and feeding of majordomo(a)hidden-foes.gateway.com. The new machine has a big more disk, a bit more processor, and is on the fast end of a T1 [the other was at my home on the good 'ole shared 28.8k SLIP]. ANYWAY----> If you were subscribed to the digest version already, you are still there. If you would LIKE to subscribe to the digest version, just send e-mail to 'majordomo(a)hidden-foes.gateway.com' with the line 'subscribe cypherpunks-d' in the BODY. The digest is created every 40k [or about 2-3 times/day it seems]. Please let me know directly if there are any problems with this new system. BTW, the first issue after moving to the new system will be Volume 2, Issue 1. Thanks, -abc
