Has anyone heard anything from the Schlafly vs PKP case? There were supposed to be patent validity hearings on Wednesday. I don't know if they are still going on, Roger hasn't updated his web page yet. Kent Briggs

Development of an Open and Flexible Payment System
by Gary Howland 17 Dec '03

17 Dec '03

Information on our payment system is now available: Development of an Open and Flexible Payment System Abstract: The Internet is in need of a simple, open, flexible and secure payment system. Many payment systems that currently exist are either proprietary, insecure, inflexible or all three. This paper examines the types of payment system in use today, the payment system requirements of Systemics Ltd., an overview of the Systemics Open Transaction (SOX(tm)) payments system that was developed, and a summary of how this system met the requirements. The SOX payment system is currently in live use for a bond trading system, and a reference implementation will shortly be made available on the Internet. http://www.systemics.com/docs/sox/overview.html

Moneychangers and Shylocks
by Timothy C. May 17 Dec '03

17 Dec '03

There've been a couple of "you must be trolling us" responses to my point about the First World spending money in the Third World not being exploitation ("and we give them worthless trinkets like penicillin, schools, and roads"). I happen to believe economic development is a positive good. Were I living in a shantytown or favelo on the outskirts of some Third World town, I would want at least the _chance_ of eventually having running water, electricity, health care, and opportunity for me and my family, Arguing that native peoples were better off before the arrival of Europeans is fatuous nonsense--you can't go home again. Further, many of the leftist critiques of "moneylending as exploitation" are similar to past (and current) demonizations of moneychangers, moneylenders, shylocks, and other assorted stereotypes. I don't favor nationalistic lending and borrowing policies, which, for example, involve some central government borrowing money, sending the borrowed funds to personal Swiss bank accounts, and then sticking the nominal taxpayers with the debt. Nothing I have said here endorses this. But much lending is useful. It's the way factories get built, the way things get done. Much of the criticism of "moneylenders" is closely related, if you think about it, to criticism of "money launderers." Cypherpunks should relish the rise of new mechanisms for money laundering, moneylending, tax evasion, etc. I took the "Wired" quote about Walter Wriston "sounding like a cypherpunk" to represent this new view, in explicit contrast to his earlier views when he headed Citibank and they had a more statist approach. Your mileage may vary, but tired homilies about lending being exploitation are not very useful in this day and age. --Tim May "The government announcement is disastrous," said Jim Bidzos,.."We warned IBM that the National Security Agency would try to twist their technology."

Re: New Bihman-Shamir Fault Analysis Paper
by Martin Minow 17 Dec '03

17 Dec '03

There is an inherent conflict between two claims that are central to the fault-analysis paper(s): "the secret key [is] stored in a tamperproof cryptographic device" and "the cryptographic key is stored in an asymmetric type of memory, in which induced faults ..." If the device is truly tamperproof, the attacker should not be able to induce faults. Even given susceptable "consumer- quality" devices, it would be trivial to store the cryptographic keys in a redundant memory configuration, such as ECC "error-correcting code" memory that can self-correct a range of failures and detect a much wider range. It would also seem reasonable to protect the cryptographic core (algorithms and data) with a digital signature that would "crash" the device, rather than proceed with incorrect key information. My naive reading of the attack suggests that storing the cryptographic key together with its one's complement would minimize the chance that an attacker can exploit asymmetric fault inducement. Finally, I'm curious whether this attack would work on masked ROM or fusable-link (one-time programmable) PROMs (not EPROMs that have no reprogramming window). These are more likely to be used in production devices than EEPROMs, if only for cost-savings. Martin Minow minow(a)apple.com

Yes, all products which may create RF radiation (e.g., personal computers) are required to pass FCC certifications (e.g., Part 15).

The war trials for the Japanese were compromised by a variety of political intrigues. Ranging from political issues regarding the best way to govern the war torn country (ie can't kill too many of them or the Japanese will simply pick up weapons again with an estimated 1,000,000 US dead as a result) to the biological weapons that were developed which were quite useful for the Allies sans the Soviets. > According to Toland: > > The US president, selected members of his cabinette and a > few admirals and generals knew - from Magic and the 'winds' > execute, radio traffic analysis, diplomatic sources, double > agents - exactly when and where the Japaneese were going to > attack, but didn't warn Hawaii, fearing that too efficient > counter-measures by the Oahu military might make the attack > abort and so not convince the isolationists. The unexpected > tactical capabilities of the Japaneese armada then made a > cover-up all the more important. Hawaii appears in *NO* MAGIC transmissions of that time period. If you, Toland, or anyone else can give specifig MAGIC intercepts I would be greatly appreciative. The MAGIC intercepts did mention Borneo, The Ka Peninsula, and the Phillipines (where the B-17's were headed that were destroyed at Pearl). The radio traffic analysis, ship movement analysis, etc. did not point to a specific target (how could they considering the breath of the Japanese opening attacks all over the Pacific) only that the Japanese were serious. The isolationists were never convinced (eg Lindbergh) that war was the right thing to do. There was nothing unexpected about the tactics. There were two previous test of shallow water torpedo attacks, both successful. The first was by the British and the second was by the US at Pearl (how is that for irony?) which was attended by Japanese observers. The heads of state and military did not seriously believe Hawaii was a realistic target and therefore looked elsewhere. Sun Tzu says the first target in war is your opponents mind, the Japanese took it to heart. Jim Choate

Even given susceptable "consumer- OK, so the authors might have better used the phrase "putatively tamperproof." Or the more accepted modern phrase, "tamper-resistant." As with safes, castles, and "bulletproof vests," all claims of absolute security are dubious. What the Bellcore and Biham-Shamir (and other, reportedly) attacks have done is to show another vector by which "tamperproof" is not. >quality" devices, it would be trivial to store the cryptographic keys >in a redundant memory configuration, such as ECC "error-correcting >code" memory that can self-correct a range of failures and detect >a much wider range. It would also seem reasonable to protect the >cryptographic core (algorithms and data) with a digital signature >that would "crash" the device, rather than proceed with incorrect >key information. Faults can be induced as well in logic devices. I agree that redundancy can be added to logic devices (I worked on this for Intel a while back), but this would require an almost complete re-doing of smartcard processors. (For starters, imagine implementing triple redundancy in smartcards....not cheap.) Again, what these recent attacks show is a theoretical avenue by which nominally tamper-resistant cards may have their defenses breached. Whether this is an important threat depends on a bunch of factors. Whether cardmakers change their chips also depends on a bunch of factors. --Tim May P.S. A while back there were a bunch of posts with the title "Professor Shamir Arrested." Was it ever established whether or not the arrested Shamir was in fact _our_ Adi Shamir? And what the charges were? "The government announcement is disastrous," said Jim Bidzos,.."We warned IBM that the National Security Agency would try to twist their technology."
