Digicash will not fly
by James A. Donald 17 Dec '03

17 Dec '03

While Chaum is a brilliant cryptographer, he is an incompetent businessman He has demonstrated this in numerous ways. The latest being "Cash" where the bank skims off 4% to 10% every time. No one is going to use digicash under these kinds of terms and conditions. --------------------------------------------------------------------- | We have the right to defend ourselves | http://www.jim.com/jamesd/ and our property, because of the kind | of animals that we are.

Hi. A group of us at the U. of Penn. are doing a presentation on STT. I would like to know if you have any suggestions for us. I've taken a look at the Visa & MS home pages and have a good amount of information on STT. I'm esp. interested in finding out about the potential weaknesses in STT. thanks, Mahesh +-----------------------------------------------------------------------+ Work Home ------- ----- 1717 Arch St., 3E4 1801 JFK Blvd., #512 Phila., PA 19103 Phila., PA 19103 (215)-466-5476 (215)-567-2006 Internet: prakriya(a)gradient.cis.upenn.edu http://www.cis.upenn.edu/~prakriya/home.html PGP fingerprint = 6A EC 5B F3 D4 33 F6 D1 4C DA 99 11 F9 D9 89 A7 +-----------------------------------------------------------------------+

If there are any other cypherpunks-readers attending the e-commerce conference in Austin on Monday and Tuesday, it might be fun to get together for an impromptu BOF either at lunchtime or later in the evening. Email me if there is interest. _______________________________________________________________________ Stephan Somogyi Senior Editor Digital Media

I'm not sure if it would be better or worse than >current setups from that point of view. One way to deflect this attack is to encrypt the message for storage using a symmetric-key algorithm with a randomly generated session key, and send the session key to the recipient with the notification. You still have 300 MB of planted kiddy-terrorist narcopornography on your machine, but it's encrypted and you can happily tell the judge that you _can't_ decrypt it because you don't have the key. The Feds _could_ get the keys by eavesdropping on your outgoing correspondence or using your system to send the material to themselves (or a conveniently employed child), but at least you're not storing it in plaintext. More of a problem with this system is that it's only useful for terminal remailers; to use it in the middle of a chain, the next remailer would need to be configured to auto-accept such messages, or else your remailer would need to have a list of known remailers and use direct delivery for all mail sent to them. #--- # Thanks; Bill # Bill Stewart, Freelance Information Architect, stewarts(a)ix.netcom.com # Phone +1-510-247-0664 Pager/Voicemail 1-408-787-1281 #---

(If you don't believe me, look into it. Start by reading the > FTL discussions about Bell's Theorem.) The actual transportation of the state is instantanious as it must be by quantum theory, just as the change in orbits of an electron occurs instantly. However, the catch is that the command/synchronization channel must be sent in parallel and it at some point can't use the quantum transportation technique and hence the speed-of-light comes back into play. This was specificaly discussed in the original quantum transportation announcement sent out by AIP. ____________________________________________________________________ | | | The most powerful passion in life is not love or hate, | | but the desire to edit somebody elses words. | | | | Sign in Ed Barsis' office | | | | _____ The Armadillo Group | | ,::////;::-.

List of reliable remailers
by Raph Levien 17 Dec '03

17 Dec '03

I operate a remailer pinging service which collects detailed information about remailer features and reliability. To use it, just finger remailer-list(a)kiwi.cs.berkeley.edu There is also a Web version of the same information, plus lots of interesting links to remailer-related resources, at: http://www.cs.berkeley.edu/~raph/remailer-list.html This information is used by premail, a remailer chaining and PGP encrypting client for outgoing mail, which is available at: ftp://ftp.csua.berkeley.edu/pub/cypherpunks/premail/premail-0.33a.tar.gz For the PGP public keys of the remailers, finger pgpkeys(a)kiwi.cs.berkeley.edu This is the current info: REMAILER LIST This is an automatically generated listing of remailers. The first part of the listing shows the remailers along with configuration options and special features for each of the remailers. The second part shows the 12-day history, and average latency and uptime for each remailer. You can also get this list by fingering remailer-list(a)kiwi.cs.berkeley.edu. $remailer{"extropia"} = "<remail(a)extropia.wimsey.com> cpunk pgp special"; $remailer{"portal"} = "<hfinney(a)shell.portal.com> cpunk pgp hash"; $remailer{"alumni"} = "<hal(a)alumni.caltech.edu> cpunk pgp hash"; $remailer{"bsu-cs"} = "<nowhere(a)bsu-cs.bsu.edu> cpunk hash ksub"; $remailer{"c2"} = "<remail(a)c2.org> eric pgp hash reord"; $remailer{"penet"} = "<anon(a)anon.penet.fi> penet post"; $remailer{"ideath"} = "<remailer(a)ideath.goldenbear.com> cpunk hash ksub reord"; $remailer{"hacktic"} = "<remailer(a)utopia.hacktic.nl> cpunk mix pgp hash latent cut post ek"; $remailer{"flame"} = "<remailer(a)flame.alias.net> cpunk mix pgp. hash latent cut post ek reord"; $remailer{"rahul"} = "<homer(a)rahul.net> cpunk pgp hash filter"; $remailer{"mix"} = "<mixmaster(a)remail.obscura.com> cpunk mix pgp hash latent cut ek ksub reord"; $remailer{"syrinx"} = "<syrinx(a)c2.org> cpunk pgp hash cut reord mix post"; $remailer{"ford"} = "<remailer(a)bi-node.zerberus.de> cpunk pgp hash ksub"; $remailer{"hroller"} = "<hroller(a)c2.org> cpunk pgp hash mix cut ek"; $remailer{"vishnu"} = "<mixmaster(a)vishnu.alias.net> cpunk mix pgp. hash latent cut ek ksub reord"; $remailer{"robo"} = "<robo(a)c2.org> cpunk hash mix"; $remailer{"replay"} = "<remailer(a)replay.com> cpunk mix pgp hash latent cut post ek"; $remailer{"spook"} = "<remailer(a)valhalla.phoenix.net> cpunk mix pgp hash latent cut ek reord"; $remailer{"rmadillo"} = "<remailer(a)armadillo.com> mix cpunk pgp hash latent cut"; $remailer{"ncognito"} = "<ncognito(a)gate.net> cpunk"; $remailer{"precip"} = "<mixmaster(a)mix.precipice.com> cpunk mix pgp hash latent cut ek reord"; $remailer{"ecafe"} = "<remail(a)ecafe.org> cpunk mix"; $remailer{"wmono"} = "<wmono(a)valhalla.phoenix.net> cpunk mix pgp. hash latent cut ek"; catalyst(a)netcom.com is _not_ a remailer. lmccarth(a)ducie.cs.umass.edu is _not_ a remailer. usura(a)replay.com is _not_ a remailer.

If not listed in conjunction with mon, then only messages destined for public forums are subject to filtering. Raph Levien
