building a better zyklon-B (Re: KRA on ADK vs KR, NAI membership)
by Adam Back 17 Dec '03

17 Dec '03

Writing about PGP's key recovery mechanism (CMR (Commercial Message Recovery) or ADK (Additional Decryption Key)), Dave Del Torto quotes from a letter he sent to info(a)kra.org: > I'm not aware of the KRA's public position on the recovery of > plaintext using cryptographically sound and ethically responsible > alternatives to the escrowing of keys in organizational situations, > e.g. PGP's Additional Decryption Key (ADK) mechanism. I don't see that ethics has any bearing on the difference between Key Escrow, and PGP's CMR "message recovery" design. They are both just yet another protocol to allow third parties to decrypt encrypted traffic. Ethics enter into the discussion when one one starts to argue about which third parties will be able to eavesdrop on the traffic. This issue is largely orthogonal to the general technique used. Parties which people are most concerned about having access to data are the spooks and governments via organisations such as NSA, GCHQ, ECHELON etc. In a commercial setting there is also some political debate about whether the employee has any expectation of privacy. One might also argue about whether it is ethical to design software which helps or makes it easy for third parties to gain access to the plaintext in general. > What is the KRA's public position on PGP's ADK? So one has to be clear of one's aims in asking KRA if they think PGP's CMR or ADK is a nice technology for adding NSA backdoors to crypto. Say, for example that they decided that CMR is neater than their CKRB mechanism. Now what? NSA/KRA lobby companies to include a modified CMR with the NSA's public key as a mandatory additional recipient? And NAI gets `asked' by the NSA to burn an NSA public key into PGP 7. Adam

Re: Securing data in memory (was "Locking physical memory (RAM) under Windows")

SCNSM 1.0 Beta, a non-swappable memory allocator for Windows 3.x/95/98, is available and can be downloaded from http://soundcode.com/content/download/products/scnsm/default.htm (docs) http://soundcode.com/content/download/products/scnsm/scnsm10b.zip (source) The SCNSM driver supports allocation of non-swappable memory on Windows 3.x/95/98. The principal design goal of SCNSM is to provide memory that will not be swapped to disk, under any circumstances. Typically, security applications require such memory to store private keys, passwords, and sensitive intermediate results of cryptographic calculations. SCNSM uses the same technique as allocating DMA buffers for hardware device transfers. The idea being that Windows doesn't swap DMA buffers and therefore won't swap this buffer either. The SCNSM source-code is copyrighted freeware. The intent here is to end the perennial nuisance of having sensitive security data swapped to disk which undermines the public's confidence in commercial security products. Please send any questions or bugs to me or support(a)soundcode.com. Jim ================ Jim Adler Soundcode, Inc. www.soundcode.com

[text deleted] Sounds cool, but I have a couple of questions: 1. Is it OpenSource? 2. I assume since it never swaps to disk the memory requirements for the computer are large. What is the minimum suggested if one runs say 5 apps that each require 16M each, 5*16M & OS overhead? And what is the suggested OS overhead with no swap to disk? (OK, that last one might be a 3rd question) ____________________________________________________________________ Technology cannot make us other than what we are. James P.

Re: Digital bearer postage stamps

Quoting Robert Hettinga (rah(a)shipwright.com) > I wonder if these guys have heard of double spending? > > Does anyone know whether this is some kind of 2-d barcode (it must be) or > is it something else? > > Cheers, > Robert Hettinga It's a 2-d barcode, with a bunch of info encoded into it.. Short answer: they use statistical security measures to prevent double spending, but they have a *scary* reputation and limitless resources to pursue fraud, something no one else really has. I would not be brave enough to double spend with this system from my home state, if I were in the US. Longer rambling answer: The E-stamp folks are pretty hardcore as far as security goes, I recall. They use a Dallas Semiconductor iButton (plug: check out the ibuttonpunks mailing list....) as a local value store, after paying for postage at a central location, and do other security measures I don't quite recall -- perhaps encoding your local post office, such that the local post office could keep its own database of double spenders, or having a global double spending database. The post office is pretty much protected from fraud, in any case -- much more than existing letters (which can be forged against high-speed equipment using a phosophor pen). I'm not sure how E-stamp protects itself from fraud, or protects its customers from E-stamp committing fraud, but I'm fairly convinced there is at least statistical security for the USPS against users. I believe the USPS published a standard during the search for a new postage system -- they did a pretty good job of it, I just never bothered to buy a copy. If someone bought a copy and mailed it to jya, it would be doing everyone a service. (Even if you have the nerve to commit bank wire fraud, check fraud, armed robbery, espionage, sedition, etc., you probably still aren't brave/reckless enough to commit postal fraud, though -- USPS inspectors make IRS auditors look passive) Cheers, Ryan ryan(a)venona.com

A tad more on Goldbach's...
by Jim Choate 17 Dec '03

17 Dec '03

I figure I'll drop a couple of more points on this since nobody else seems to have twigged to them.... Goldbach's original conjecture is crap. There is NO way that 3 odd numbers will ever equal an even number. Odd + Odd is Even. Even + Odd is Odd. Fermat was a hell of a lot more charitable to the original assertion than I would have been. Goldbach's existing conjecture can be worded another way: Any even number may be represented by the sum of 3 even numbers provided two of the numbers are 1 less than a prime and we add 2. It's obvious that an even number can always be the sum of other even numbers, it's axiomatic. The question actualy is: Is the set of even numbers whose members are one less than the corresponding member of the primes sufficient, when added to 2, to sum to all the even numbers. As far as I can find nobody has written a lot on patterns of even numbers 1 less than the odds. There's not even a name for the set that I can find. As to somebodies assertion that an odd number can be represented by the sum of two odds, better study your math a tad better. Odd + Odd is *always* Even, never Odd. Happy Thanksgiving! ____________________________________________________________________ Technology cannot make us other than what we are. James P. Hogan The Armadillo Group ,::////;::-.
