Let me start by saying that my opinions may or may not count for much, as I don't pursue cryptography as a career, but rather as an interested observer. I also subscribe to the belief that software patents serve no useful purpose except to enrich the coffers of large corporations, all the while inhibiting useful work. Anyway, I just finished reading the IEEE Spectrum special issue on data security and I really have a hard time believing that they could present such a biased view of the NIST DSS issue. I also had a similar problem with the sneering attitude presented in the Communications of the ACM special issue on cryptography. In both magazines, the editors introduction to the issue carried a sneering tone and implied that anyone who didn't immediately go out and jump on the RSADSI bandwagon and whole-heartedly support this ``de facto industry standard'' must perforce be a lackey of the NSA. The ACM articles allowed Rivest, et al., completely free rein to spout off with criticism of the NIST DSS, which seemed to boil down to three main issues: 1) RSA has a bandwagon - you better jump on! 2) NSA advised NIST on DSS -- they must have inserted a trap door! 3) 512 bits won't work as a maximum key length. In other words, both magazines allowed people with vested *financial* interest in one side of the issue to present their personal views as scholarly criticism of the NIST DSS. I personally find it hard to go along with the RSA bandwagon argument. Supposedly, the RSA patent has existed for *ten* years already. In that time, where one might expect to see a product or two. I don't see *any* products on the market. This reminds me of the ACE bandwagon, the OSF/1 bandwagon, ... Overall, I think the IEEE did a better job of presenting the NIST/NSA side of the issue -- the ACM articles only managed to do a lot of sneering and giggling about how inept NIST acted in allowing NSA in the door. I also admit to some distrust of the NSA. However, in spite of years of criticism of DES and lots of people speculating about trap doors, none seem to exist. I want to see a discussion of the pros and cons of DSS, not sneering remarks and specious arguments. I also want to see a *national* level debate of how the ``crytpography as munitions'' policy costs the US in terms of lost business, lost competitive edge, etc. Overall, the ACM articles disappointed me since I expected scholarly behavior and I got childish sneering and name calling. The IEEE articles raised real issues of policy and actually allowed the NSA and NIST to defend themselves, but still stooped to sneering and specious arguments, especially Rivest's response to the NSA. Bidzos at least brought up real policy issues about competitiveness in addition the the ``hop on the bandwagon'' cheer. I expect better of both magazines. /Joe Obviously my personal opinions.

I also read the ACM issue, but my reaction is quite different. The main
complaint that people had about the proposed NIST scheme is that it had
appeared out of nowhere, with no adequate chance for public review.
Design of cryptographic schemes is very difficult and nobody takes a
scheme seriously until it has withstood attack for quite a while. One of
the articles pointed out some fairly obvious bugs in the proposed scheme
which makes one wonder whether they'd tested it at all.
The RSA patents are annoying, but RSA does have the advantage that it's
been around for over a decade and has withstood attack.

In most fast moving technical fields, all the experts have a financial
interest on one side or another. This doesn't disqualify them from having
useful opinions. Rivest et al. make no secret of their affiliations, and
even keeping that in mind I found their counterarguments to the NIST
scheme compelling.

John, please retract your statement. Nowhere in the July 1992 CACM issue is there any hint of Rivest's association with RSADSI. In CACM Rivest states ``DSS is different from the de facto public key standard (RSA).'' Of course RSA is not the de facto standard; see the letter by Stallman, Minsky, et al. in prep.ai.mit.edu:pub/lpf/bidzos.r*. And Rivest does not point out his financial interest in claiming that RSA is a de facto standard. Rivest states ``Public Key Partners (PKP) asserts that DSS infringes U.S. patents #4,200,770 and #4,218,582.'' Needless to say, PKP and RSADSI are for all intents and purposes the same company---but Rivest doesn't point this out. Rivest also does not point out his financial interest in the two patents he cites. ---Dan
