Ross TCPA paper
by Larry J. Blunk 24 Jun '02

24 Jun '02

For those who question the use of the TCPA spec as part of a DRM system, I refer you to the following article where the author interviewed Jim Ward of IBM (one of the authors of the TCPA spec) -- http://www.101com.com/solutions/security/article.asp?ArticleID=3266 In particular, note the following text: "The TCPA specifications center on two main areas: trusted reporting and public key infrastructure (PKI). The TCPA reporting guidelines create profiles of a machine's security settings as the machine boots. Ward says content providers such as Bloomberg or Hoover's may take advantage of this feature to ensure users do not redistribute content." And then there is the DRMOS patent granted to Paul England, et al. of Microsoft -- http://cryptome.org/ms-drm-os.htm. Mr. England is also one of the authors of the TCPA specification. Note the section describing the interaction of the DRMOS with the CPU and the cryptographic/certificate requirements of the CPU. This is precisely how the TCPA spec works. The TCPA website avoids mentioning the DRM applications of the spec precisely because it is so controversial. However, it's no big secret that this is clearly one of the intended uses of the spec. ------ Larry J. Blunk Merit Network, Inc.

We run the main MTA for my university this way (of course it will relay without authentication if the client source address is within the university IP ranges), using sendmail and cyrus-sasl. It's my impression that many US universities are starting to do this. We started it as a one-off MTA handling submission of mail for travelers, then realized that the regular MTA could just provide this service. It also does Kerberos authentication, which I use (though not many MUAs support it). > Since more and more misguided ISP's are flat out blocking outgoing > connections to port 25 from inside their network, I have postfix > listening at a higher port number in addition to port 25, just as many > hosts today are running sshd on several ports to help compensate for > similarly misguided corporate firewall policies. The obvious port is 587, the "submission" port (see RFC 2476), which in fact is the one that MUAs "should" use, rather than 25 (we support it, I'm submitting this mail using it, via my home ISP). Of course if it actually becomes popular those misguided ISPs will block it too ... - RL "Bob" --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to majordomo(a)wasabisystems.com

RE: DOJ proposes US data-rentention law.
by Trei, Peter 24 Jun '02

I tried sending this last week, but it did not seem to go through: Two points: 1. According to Poulson, the DOJ proposal never discussed just what would be logged. Poulson compared it to the European Big Brother legislation, which required storage to Web browsing histories and email header data (NOT email body text or IP traffic). 2. After I posted the same info to /. http://slashdot.org/articles/02/06/19/1724216.shtml?tid=103 (I'm the 'Anonymous Coward' in this case), Kevin updated his article. The new version may be found at: http://online.securityfocus.com/news/489 The relevant portions read: - start quote - U.S. Denies Data Retention Plans The Justice Department disputes claims that Internet service providers could be forced to spy on their customers as part of the U.S. strategy for securing cyberspace. By Kevin Poulsen, Jun 19 2002 12:24PM [...] But a Justice Department source said Wednesday that data retention is mentioned in the strategy only as an industry concern -- ISPs and telecom companies oppose the costly idea -- and does not reflect any plan by the department or the White House to push for a U.S. law.

The Revolution Will Be All Business
by R. A. Hettinga 24 Jun '02

24 Jun '02

http://www.anti-state.com/kennedy/kennedy4.html The Revolution Will Be All Business by John T Kennedy Many market anarchists continue to embrace the paradigm of the political movement. They believe that the society they favor can only come about when enough people have been persuaded of the benefits or moral correctness of such a society. Thus they seek to build a movement. I have good news and bad news. The bad news is that there is no market anarchist movement and there is never going to be a market anarchist movement. Better mass marketing of market anarchist principles will not advance market anarchism. Rational evangelism will not convert the masses, or even a critical mass of individuals, to market anarchism. The entire project of building a movement is misguided and of no use to market anarchists. The impulse to build a movement is collectivist in nature; it is rooted in an egalitarian and even democratic view of society. The idea is that when enough people come to see what is truly in their common interest, they will voluntarily cooperate to secure that common interest. It's not terribly surprising that many would have difficulty escaping this mindset, it's not far from the democratic ideals set forth by the Founding Fathers, ideals that we are taught to revere from an early age. But these democratic ideals are not appropriate to market anarchism and they will not advance it. Did I say there was good news? The good news is that a movement is unnecessary. It's difficult to get this idea across to those still stuck with the paradigm of the political movement. They tend to not even hear it. In A Porcupine's Worth Is His Price I wrote: "Some advocates of anarcho-capitalism think that to achieve liberty from government we need to convince a majority or some critical number of people that anarcho-capitalist society will be better for them than governed society. The porcupine teaches a different lesson - that men will be free from government whenever they become too expensive to govern." Bob Murphy saw in this passage only a "compulsive need", on my part, "to engage in product differentiation". He asks "How are these two statements different? You're claiming that there isn't some critical number of people necessary to become free?" I was trying to say plainly that it is not necessary to persuade a critical number of people of the merits of market anarchism in order for people to become too expensive to govern. The question, along with other evidence, persuades me that the message is not being heard. I'm accused of being a fatalist because I say there will be no movement. I'm accused of being a cynic because I say that rational evangelism won't work. But I'm neither a fatalist nor a cynic. I'm an optimist. How can market anarchism come about without a movement? This is the essential question that is asked again and again. But the question is almost always asked rhetorically, the person asking is not looking for an answer because he's already decided that none is possible. So when an answer is offered that answer tends not to be heard, or else it is quickly forgotten. I asked the same question, looking for answers. And there are answers. That's the good news. There is a model of voluntary collective action appropriate to market anarchism. It is business. A business is not held together by a rational argument persuading individuals to pursue a common goal; a business must primarily appeal directly to the self-interest of employees and customers. A successful business must deliver value to both employees and customers on an ongoing basis. A business does not require a critical number of participants; in some cases very small groups of individuals can produce dramatic results within the framework of a business. Consider Assassination Politics. I do not advocate AP because I do not think it would operate as its creator intends; I offer it only as an example of an approach to advancing market anarchism. If AP worked as intended people would become too expensive to govern, since those who sought to govern could expect to pay with their lives. There would be no need to persuade people to use AP; they would use it out of self-interest. In theory, a small team, perhaps even an individual, could implement the guts of AP. The full implementation of it would require a business, but certainly not a huge business. The project would be quite lucrative, which is why certain individuals would be willing to attempt it. And this business would change the world, assuming that AP worked as advertised. Look Ma: No movement. AP is not the answer, but it is the right kind of answer. It's a business. What kind of businesses can advance market anarchism? Businesses which make people more expensive to govern. Businesses which offer their customers the means to protect their property and their persons from government. One of the highest leverage possibilities is a business that offers its customers the means to shield their income from taxation. Taxes become voluntary to the extent that individuals can avoid them, and when taxes become sufficiently voluntary governments must fail. What is the incentive for businesses to offer such services? Such businesses would be going after a piece of the same massive revenue stream that governments now control, the financial rewards would be immense. I don't expect one business to step forward with a turnkey solution for individual freedom. Rather I expect lots of businesses to attempt to carve out their own share of that revenue stream, each of them making people a little bit more expensive to govern. The cumulative effect will be the same. If you can provide people with the means to protect their property and their persons from government you won't need to waste any breath persuading them to do so. They will overwhelmingly do so out of self-interest, regardless of their political views. Government can be seen as an attempt to solve public goods problems by punishing those who defect from cooperating with the collective. The problem with this solution is that we become prisoners of government. Our Prisoner's Dilemma is that we'd all be better off if we collectively defected from government, but individually we can incur severe penalties for defection. The solution to the dilemma is to introduce agencies which can reap tremendous rewards for protecting individuals from the penalties government can inflict, businesses, which can reap tremendous rewards for enabling their clients to defect from government without penalty. Worry about marketing market anarchy when you have a viable business plan. Forget movements. The business of market anarchy is business. June 19, 2002 discuss this article in the forum!
