T1 insecurity (was Re: Remailers and ecash)

shamrock(a)cypherpunks.to: > Once you have all the mail going in and out, you make use of the simple > fact that Type 1 messages must shrink with each hop. See the classic > essay "Mixmaster & Remailer Attacks" at > http://www.obscura.com/~loki/remailer/remailer-essay.html This describes a pure Type 1 without a remix feature. This idea due to Andy Dustman allows Type 1 and 2 remailers on the same host to cooperate, hiding the message size and type. Another fault of pure Type 1 blocks when reused is that they are easily recognisable as the same stage of the same block on different occasions. You can do sneaky things with cutmarks, but it doesn't buy you much. You can point your reply blocks to a message pool, so avoiding the worst effects of Type 1. You still (even with mixmaster) have the timing issues involved with addresses that communicate regularly. > If you run a Type 1 remailer, do your users a favor: shut it down and > replace it with a Type 2. Say this when there's a good way to receive anonymous email. The sooner the better. Meanwhile all Type 1 remailers should remix. And as far as fitting ecash into headers is concerned: Ulf and I think that you could cannibalize the 2nd header to contain the cash. (We were talking about hashcash in fact.) You'd need to avoid sending cash to remailers that wouldn't read it, and you'd reduce the maximum number of hops permissible. I was meaning to add hashcash to these remailers. Lucky's persuaded me not to do it to t1. -- ############################################################## # Antonomasia ant(a)notatla.demon.co.uk # # See http://www.notatla.demon.co.uk/ # ##############################################################

Re: remailer latencies

Monty, Just so you know that the less-than-100-percent message rate doesn't necessarily mean that messages are getting lost: Last update: Tue 30 Sep 97 15:09:32 EDT remailer email address history latency uptime ----------------------------------------------------------------------- bureau42 remailer(a)bureau42.ml.org -----------+ 3:31:14 100.00% It's a fluke; I just happened to look at this list (by fingering rlist(a)anon.lcs.mit.edu) while I'd been on the net for a while, and so no messages were in transit. Mere seconds later, the EFGA list showed my uptime as 99.97% and Raph's list showed a meager 94.08% (it looks like somewhere, about three days ago, messages got dropped somehwere). On balance, the remailer network is rather more reliable than you seem to give it credit for. (Side note: the more reliable remailers, with bureau42 being a notable exception :) tend to be faster too. The top remailers as of _right_now_ all have reliability above 99.90% and delay times less than twenty-five minutes. Chain a few of those together and your message will almost certainly arrive in less than an hour. Few would argue that that's an unacceptable delay. Messages routinely take longer than that to be delivered, due to random nameserver burps and other "normal" factors.) dave (bureau42 gearhead)

Pauline hanson's One Nation Newsletter
by Global Web Builders 17 Dec '03

17 Dec '03

Pauline Hanson's Monthly electronic newsletter: October 1997 Issue: 1.3 nsw There are several issues that we would like to cover this month. They are all very important and need your support to create the momentum we need to address the wrongs that are currently taking place in Australia. ___________________________ 1) Petition to the Prime Minister: Firstly please take a moment to sign the on-line petition to the Prime Minister's office demanding that he not be pressured into putting One Nation last on the How to Vote cards at the next Federal Election: The petition is at: http://www.gwb.com.au/petition.html ___________________________ 2) The Canadian experience - Canada is now being divvyed up into independent states. Pauline Hanson's press release at: http://www.gwb.com.au/onenation/press/011097.html looks at the implications to you. The architect of Canada's break up is now living in Brisbane and advising the Aboriginal Central Land Council on how to go about divvying Australia up into a number of Aboriginal States financed by the Australian Federal Government! ___________________________ D O N A T I O N S P L E A S E...... 3) One Nation is growing (we now have nearly 200 branch offices established) and we need you to put your hand in your pocket to keep this growth on course. We have established a web site called 'Take a byte for Australia'. http://www.gwb.com.au/pledge.html We aim to raise $100,000 through the Internet during this financial year. We know that this is a big ask but if you believe that the on-line service provides value and if you would like to help One Nation please 'Take YOUR byte for Australia now'. A gauge will display how well we are going towards achieving this target of on-line donations to One Nation. You can print out a donation form and send it to Pauline Hanson's One Nation head office in Sydney. Donations of up to $100 are fully tax deductable. ___________________________ 4) Important Internet addresses: Pauline Hanson's One Nation: http://www.gwb.com.au/onenation Pauline Hanson's One Nation press releases: http://www.gwb.com.au/onenation/press/press.html The Hanson Phenomenon: http://www.gwb.com.au/hanson.html Archive of One Nation launch and branch launches: http://www.gwb.com.au/gwb/onenation ____________________________ Thank you for your support.

Latency may be a means to get security in the current remailer design, but it is a means to the end and not the end itself. This doesn't mean we shouldn't use latency to get security, but it is undesirable, like using cinderblocks for construction. The reason I point this out is that it is important to separate design choices to achieve a goal from the goal itself. If we had a remailer network in which each customer had a constant bandwidth connection to one or more remailers, you could have zero latency mail. (Actually, this would be nice to use with those Comsec phones.) It is my understanding that serious naval vessels like aircraft carriers use constant bandwidth channels to defeat traffic analysis. That is, to every place they might wish to communicate, they continuously broadcast encrypted information. Most of the time the channel is empty, of course, but nobody outside can tell when.

Any company which desires to suppress opinions or discussion over their product clearly has something to hide. This is what I tell my customers and they seem to understand the utility of such an approach.
