For the last time: I have nothing to do with Netscape. So, please, stop making silly associations. What I do to defend my opinions it to try and get more people involved in the subject, explain the problems in terms they can understand, discuss with them about possible solutions (sometimes they have better ideas than me) and try to promote an effective course of action. And in any case that's *my* business. Being in a different country and even continent, what I do may not be of any direct consequence to you. And since I have nothing to do with any commercial company -hey I don't even use Netscape- it has no relationship whatsoever with Netscape or any other company. If you think that people likes to hear complains, go along. In my experience people is more cooperative when they see better solutions than just making a boicott and renouncing to use things they like. So, I'll keep on explaining what crypto can do for them and how easy it is to be taken advantage of. And how easy it is for them to press and get what they deserve. WRT legal courses of actions, just remember there's a whole world our your privy. It's sad you don't know better, but if you look around carefully you'll discover that many of the proposed actions are not feasible in many places. Just go out of your shell. I haven't either. I wouldn't be here if I did. jr

Uh-oh! I'd better shut down my remailer, but fast, based on an unsubstantiated rumor. Especially one that makes little sense. Why do you need a sting? All you have to do is use a single remailer, and send the mail from yourself, to yourself. You know the source, destination, and who handled it. IF a court can be convinced that forwarding email containing illegal materials is the same as asking to receive email containing illegal materials, then ALL of our butts are toast. > My questions are a) is it possible to perform this type of > monitoring on a mixmaster remailer and, b) what is the identity of the > cooperating remailer operator? > > This concerns me greatly as I use remailers to privatize my > important email regularly and I don't want my identity or my email > compromised because of a "spook in cypherpunks clothing". You fool. If you use remailers regularly, then YOU ARE KNOWN TO THE SPOOKS. Face facts. We know that the FBI spends a minimum of $10,000,000 each year (count the wiretaps, multiply by agents and do the math) just for telephone wiretaps. Computer wiretaps are a LOT CHEAPER. -russ <nelson(a)crynwr.com> http://www.crynwr.com/~nelson Crynwr Software | Crynwr Software sells packet driver support | PGP ok 11 Grant St. | +1 315 268 1925 voice | Flushing, NY.

Every week, this new column will feature questions from readers about a given topic. You can send questions as well as suggestions for topics you'd like to see Miller address in future columns. As Miller puts it: "My print column is really an essay on a particular topic. I try to focus on a broad variety of things, although most my print columns have been Internet-related lately. That's not too much of a surprise, as I've been spending a lot of time working with new tools and content for the Internet. This column will be more conversational. It will give me an opportunity to answer reader questions and address their concerns. In addition, this Q&A will be more timely than my magazine column because it doesn't have to be printed, bound, and mailed."

Re: Info on Netscape's key escrow position
by James M. Cobb 17 Dec '03

17 Dec '03

Blanc, On 12 02 95 you pointed to: ...an underlying problem, which is of not having a sense of freedom to stand up to the Dark Side. You have put your finger on perhaps THE problem: Why did we cast aside our sense of freedom? How may we re-ignite the spirit of freedom? I believe excerpts from a newsstory in today's Electronic Telegraph provide a hint regarding the first question: JOHN Major and Lord Taylor, the Lord Chief Justice, are to have informal talks at No 10 Downing Street in an attempt to avert a deepening rift between Government and judiciary. The meeting has been arranged following concern over the number of adverse court judgments against ministerial de- cisions and mounting opposition by judges to plans by Mi- chael Howard, the Home Secretary, to impose tougher man- datory sentences on habitual criminals. It was being emphasised in Whitehall last night that the in- formal meeting was intended to explore ways of improving relations. It was in no sense an attempt to put pressure on the judges. It emerged last night that Mr Major and Lord Taylor are like- ly to discuss ways of increasing the pay of the judiciary. Senior judges are said to be aggrieved that their salaries have fallen behind. In no sense is one part of the the State putting pressure on another part of the State... Through every sense, the populace is trained to appreciate the justice of not having a sense of freedom to stand up Except at the pay window. Cordially, Jim NOTE The URL of The Electronic Telegraph's website is: http://www.telegraph.co.uk The newsstory's headlined: "Pay and peace talks for judges." Its online filename is: 1judge05.html. It's dated 12 05 95. The story was written by: GEORGE JONES and TERENCE SHAW.

Secure versus ?
by solman＠MIT.EDU 17 Dec '03

17 Dec '03

Thanks to everybody who replied to my previous message. As most of you suspected, it turned out to be possible to break the permutations I was using. The reason why I have pursued this despite its non-intuitiveness is that the following well known protocol also seems to have the same property I claimed. Please tell me how a computationally unbounded adversary could defeat the following: (without active attack against which this immediatelly fails (i.e. it has to be combined with an authentication algorithm)). Please help me, this problem is totally driving me crazy! A VARIATION OF SHAMIR'S THREE PASS PROTOCOL SAFE FROM PASSIVE ATTACK BY A COMPUTATIONALLY UNBOUNDED ADVERSARY: Alice wants to send Bob a message. She is going to send her message a fraction of a bit of a time via the following protocol. Before hand: 1. Enumerate all the primes from 256 to 511. Call them N. 2. For each prime, enumerate all the numbers less than it that are also relatively prime to N-1. Call these E. 3. Number each pair of E and N. The algorithm can be divided into an inner loop and an outer loop. The outer loop calls the inner loop. Inner Loop: Alice wants to use the inner loop to send bit b. 1. Alice randomly chooses seven bits of salt, and prepends b to them creating an 8 bit M 2. Alice randomly chooses an (Na,Ea) pair from the list of possibilities. 3. Alice calculates D such that E*D mod (N-1) equals 1 4. Bob randomly chooses an (Nb,Eb) pair from the list of possibilities. 5. Bob calculates D 6. Alice sends Bob the nine bit number (M^Ea) mod Na = C1 7. Bob sends Alice (C1^Eb) mod Nb = C2 8. Alice sends Bob (C2^Da) mod Na = C3 9. Bob calculates (C3^Db) mod Nb = M, the bit being the MSB. The unbounded passive adversary calculates a probability (p) between 0.5 and one with which he/she can guess the bit. This is based on the facts that 1. only a fraction of all pairs of Na and Ea will map C2 to C3, 2. only a fraction of all pairs of Nb and Eb will map C1 to C2, 3. only a fraction of all Na are high enough to produce C1. With thousands of transform pairs, there are more bits of entropy in the transform and salt selection, than there is information in the three messages. Alice, Bob and Eve can thus know what p is. Outer Loop: 1. Alice sends Bob an initialization vector using the inner loop. 2. Alice uses the inner loop to send Bob a series of bits. Each bit is either a random bit or the next bit of the message depending what the value of p for the previous inner loop was. A simple proper (but VERY INEFFICIENT) outer loop algorithm would be the following: Alice: 1. If the p for the previous inner loop was 0.5, send the XOR of the message and the previously sent bit. 2. If the p for the previous message was not 0.5, send a random bit. Bob: 1. If the p for the previous message was 0.5, take the bit, XOR with the previous bit, and append it to the message. 2. Otherwise just save the bit for one more itteration. PLEASE help me. I CAN'T find how this fails to be information-theoretically secure, but I am convinced that it should not be possible to do this, and I have been absolutely unproductive at anything since I first started working on this. Cheers, Jason W. Solinsky

Do companies ever do the "right thing"?

Remember, corporations are in business to >make money by providing a product or service that people will pay >money for. Whatever gets in the way of that will fall by the >wayside. That's an economic fact of life. I can think of many cases where companies chose courses of actions that seemed to be motivated by choices about what is right and what is wrong. Viewing the "profit landscape," corporations have to balance movement to the "locally most profitable" regions (fertile valleys) or to movement further out into even more profitable regions. It is just not that case that all corporations make decisions about what is the "most profitable," at any cost. They have Boards of Directors with influence, and they have various sorts of "mission statements." This applies to small businesses as well, where the owners often make decisions about which markets to compete in based on their own personal moral choices. Vegetarian restaurants, for example, choose not to offer meat, even when market studies indicate their patronship would probably increase. I also know of electronics companies that, for various reasons, refuse to bid on government contracts. (Partly they fear sinking into a bureaucratic mess, partly they don't want to do military work.) Finally, many companies understand the value of "good will" (as we discuss so often in talking about reputations) and think carefully about how their actions will be perceived _long into the future_. It is the belief, I think, of most of us that Netscape will have its reputation diminished if it acquiesces without a strong fight to government plans for GAK. In this sense, if we are right, Netscape's longterm profits may be affected by their choice. --Tim May Views here are not the views of my Internet Service Provider or Government. ---------:---------:---------:---------:---------:---------:---------:---- Timothy C.

Re: Meeting notes from ANSI X.9 Meeting on Electronic Payment

From: IN%"pfarrell(a)netcom.com" 5-DEC-1995 02:49:01.83 Accountants know how to meet acceptable auditing standards when transactions are in cash. I learned this from the CPA I live with. ----------------- How does this work? While I can see tracking expenditures (i.e., the advertized price of an item and the amount of that item purchased by a store), it would appear decidedly more difficult in the case of service companies (and even more so for self-employed individuals). I am not referring to a company being able to keep track of its own books; I am referring to the IRS accepting those books as the real ones, when a large part of the company's income is in cash and therefore hard to trace. -Allen
