User talk:Sandy Harris

Welcome!

Welcome to the Citizendium! We hope you will contribute boldly and well. You'll probably want to know how to get started as an author. Just look at CZ:Getting Started for other helpful "startup" links, and CZ:Home for the top menu of community pages. Be sure to stay abreast of events via the Citizendium-L (broadcast) mailing list (do join!) and the blog. Please also join the workgroup mailing list(s) that concern your particular interests. You can test out editing in the sandbox if you'd like. If you need help to get going, the forums is one option. That's also where we discuss policy and proposals. You can ask any constable for help, too. Me, for instance! Just put a note on their "talk" page. Again, welcome and have fun! D. Matt Innis 10:40, 22 December 2007 (CST)

hi and welcome

Hi Sandy, Welcome to the Citizendium, and thanks for editing in the Computers Workgroup.Pat Palmer 20:38, 22 December 2007 (CST)

forums

Sandy, re: your enquiry on my user page, I believe the forums have been phased out, and people are encouraged to use the mailing lists instead. You might also post on the Computers Workgroup talk page if you have a suggestion for work someone might want to do.Pat Palmer 11:57, 28 December 2007 (CST)

Pat, I don't know where you got that idea -- the Forums are VERY active! I think, in fact, that that is where just about all of the discussions are going on.... Hayford Peirce 12:30, 28 December 2007 (CST)

I can clarify this. For general project discussion, the forums are the place to go. For discussion of workgroup-specific issues, go to CZ:Mailing lists. There are still workgroup-specific boards, but they are now discouraged... --Larry Sanger 12:34, 28 December 2007 (CST)

So far, after a dozen or so attempts on several different days, I've been completely unable to reach any forums. I suspect the Great Firewall of China is blocking them. Sandy Harris 12:43, 28 December 2007 (CST)

Still not accessible to me. Fine if I use a proxy, so it seems clear the Great Firewall has blocked them. Of course I can bypass that, but I am not willing to do so routinely. It slows performance a good deal and creates risks -- to me since it may be illegal under local laws and to others since if I over-use a bypass technique, the Chinese gov't are more likely to catch on and block that technique.

So I will use forums only if I think something I could do there is very important. Sandy Harris 09:59, 10 October 2008 (CDT)

Today they work. Sandy Harris 05:19, 21 November 2008 (UTC)

Well, I've extracted part of the broader discussion, to prepare a draft of the first navigation idea to go into the formal CZ Proposal system. See User:Howard C. Berkowitz > Strong Articles. I've gotten some feedback in email that I'll try to put in later tonight, or tomorrow. Hopefully, it can start in the Proposals system sometime next week. Howard C. Berkowitz 05:59, 21 November 2008 (UTC)

And today they are not accessible except through a proxy. Sandy Harris 10:01, 23 November 2008 (UTC)

For the last couple of months, the forums have been working fine for me. Perhaps the Great Firewall is now allowing that link. No telling whether or when it might be blocked again though. Sandy Harris 05:26, 24 August 2009 (UTC)

It seems to be consistent. It is now at least six months since I've seen a forum connection failure, although I do check the forums moderately often. Sandy Harris 02:44, 7 March 2010 (UTC)

one-time pad

Hi! Thanks for your notice. I've changed the status accordingly and left a note on the talk page so that the copyright issue is clear. Please note that imported articles are supposed to be improved here. The external content just copied from elsewhere and not developed further on Citizendium sooner or later gets deleted. An article that is improved becomes CZ_Live; still, it retains a notice about the original source (BTW, you may be interested in adding such a note at the bottom of your article). Cheers! Aleksander Stos 10:19, 17 January 2008 (CST)

Comment on CZ:Bold Moves addition

Moved from CZ:Bold Moves (which is just a log, not a discussion forum):

Sandy, I am unclear about what you're trying to do - and what is One-time pad is all about? Can you help me? And welcome to CZ, by the way! Stephen Ewen 02:44, 21 March 2008 (CDT)

Network architectural models

I appreciate your mentioning concerns on the talk page before making major changes. Now, since I wrote some of the articles in question, my "authority" as a Computers Workgroup editor cannot be asserted, due to conflict of interest.

Nevertheless, we really do need to discuss certain things on article talk pages. First, a great many real-world network architects and protocol designers really wish, for very specific reasons, that the OSI model be discarded as a teaching tool. It introduces many obsolete concepts or things that are just wrong, especially when the teacher tries to force incompatible Internet concepts into it. There is more relevance, at least with respect to telephony, to considering the SS7/ATM model, with due regard that even there, SIGTRAN is moving SS7 to an IP framework, and, while optical communications are very much alive, ATM itself is more historical; its assumptions involved some technological dead ends that, for example, did not predict that extremely fast routers do not need fixed-length cells.

I've commented on one example under VPN. Again, it may be a good idea to stress that not all models are PPVPN, but the terminology from PPVPN is useful and quite general in the IETF.

Existing VENONA article

There was already a substantial article, VENONA, before you deleted my reference to the primary source in cipher, and then created Venona. Please stop deleting citations and redirecting away from existing work. I have asked for assistance from the Constabulary.

I have indeed cited some of my own outside work on Citizendium, but I put prominent disclaimers on the talk page or referred only to peer-reviewed published material. There is no obvious peer review of the external material that you wrote. If you want to cite your own research, one way to do so is under the signed articles subpage. Howard C. Berkowitz 21:29, 2 August 2008 (CDT)

I am not "being silly" about having citations in relevant places; I am following consensus practices about putting references where they are relevant. If you don't think pseudorandom numbers are relevant to one-time pads, I'm not sure quite what to say -- except this is the sort of thing that tends to be an Editor call on CZ. It might be useful for you to discuss this with another Computers Workgroup editor, or a Constable. Do you understand that a workgroup editor has some content responsibility? Howard C. Berkowitz 21:57, 2 August 2008 (CDT)

Do not move citations without consensus, or when a relevant Editor states they are relevant in the place they are, unless you get a Constable or uninvolved Editor to mediate and/or arbitrate the matter. This is not Wikipedia, and we do not get into edit wars. I have added citations, where I felt they were appropriate, in my judgment as an Editor. I'm not sure what you are trying to accomplish besides confrontation. This is a sincere attempt to improve quality, but you seem unwilling to consider any opinion other than your own; I'd rather not have to see this enforced by a constable. Howard C. Berkowitz 23:13, 2 August 2008 (CDT)

I have commented at Cipher. Please remember to use the talk pages on these articles to avoid misunderstandings. Constable D. Matt Innis 08:48, 3 August 2008 (CDT)

It's a party, and you're invited!

Hi ! Your CZ Write-a-Thon MC here. Please head over to the Party Room and add yourself to the list of revelers in whatever category you think appropriate. Thanks for contributing! Aleta Curry 18:41, 6 August 2008 (CDT)

Starting some new material for cryptanalysis.

On the talk page for now -- I'll use a sandbox if it gets too big -- I'm doing some suggested basic text on "tactics" that go before strategy. They are quite basic, but a beginner may need them. Give me a little time to get out a rough draft: it's 1200 my time; I want to spend 30-60 minutes on this. I won't touch the main article until doing this. Howard C. Berkowitz 16:03, 17 October 2008 (UTC)

categories

At citizendium there is no need to manage the categories at the bottom of each page. We have a metadata page associated with each article; the one for ULTRA is at Template:ULTRA/Metadata. You'll notice that along with removing the categories from the article I made another edit to the metadata. That edit allows the subpages template to now place the correct categories on the article and all the subpages (notice the correct categories are still at the bottom of the page despite the fact I removed them). This has the advatange that we do not need to make many changes when we wish to add/change or remove a category. You can read more at CZ:Subpages. Chris Day 14:17, 20 October 2008 (UTC)

I gave you the wrong link. The more informative one is at CZ:Using_the_Subpages_template. Chris Day 14:06, 22 October 2008 (UTC)

Good work development

I know it's in flux, but I like what you are doing in moving some of the materiial from cryptographic snake oil to cryptography. You make the correct general point that some of this refers to security beyond cryptography.

As I think I've mentioned, I started an article, communications security, but am not happy with the title and have various thughts of developing it, with the clear intention that the article is about the goal and the abstract requirements (e.g., content confedentiality, atomic integrity). Now, those particular requires are most often met with cryptography (nods head in direction of covert channels, steganography, etc.).

There are, however, goals, more on the hardware side, that are minimally, if at all, implemented with cryptography, such as low-probability-of-intercept and direction finding. Yes, LPI can use a synchronized PRNG for frequency agility and spectrum spreading. Physical protection is very different for an antenna and a communications line.

At the other end of the spectrum, there are things like privilege levelsl, mandatory access control, etc., that are primcipally in software rather than the network or the transmission system. Again, they may make use of cryptography, as in digital certificates for authentication, but biometrics and multi-factor authentication need not depend on cryptography.

I think we need that unifying article — information assurance is one term that might fit, although I've never liked it. Information assurance, though, also picks up fault tolerance.

As I say, I'm frustrated and need some fresh eyes on it. Could you give me your opinion? If you think some of the non-cryptographic security material you are moving out of snake oil might fit better there, feel free to try to work them in.

The workgroups are getting very complex at this point -- mathematics and computers are pretty easy, but engineering, physics, law, and other fields touch. Howard C. Berkowitz 04:16, 23 October 2008 (UTC)

Could you look at ..

Hi, I haven't forgotten this, just haven't had the time (yet) to give it enough attention to have something intelligent to say. If I can get done with Crash of 2008 I'll try and make time. J. Noel Chiappa 18:56, 30 October 2008 (UTC)

PS: Thanks for all the hard work; I haven't had much time for articles yet, I seem to be busy with other stuff, but maybe some day I can join in too. J. Noel Chiappa 18:56, 30 October 2008 (UTC)

Your testimony

Please let us have it! --Larry Sanger 21:01, 3 November 2008 (UTC)

Electronic probing

Sandy, I remember you asked whether there was a term used for active measures to tease out information useful for cryptanalysis, but I don't remember which talk page had it. Anyway, you might want to look at electronic warfare#electronic probing. It's different than what you described, but you might want to link to the heading/reference and build on it.

Personally, I would't think it too much like original research even to create as small article titled something like "cryptanalytic probing", link to the EW definition, and explain that the term introduced is an organizing article to pull together several non-obvious common threads. "Organizing article" isn't a wonderful term, but occasionally, the function, if not the name, is needed in a knowledge navigation structure. Howard C. Berkowitz 02:18, 9 November 2008 (UTC)

Developing articles of interest

If you haven't seen them, there are two groups of articles that might tie to some of your interests, and be worth some cross-linking. User:David MacQuigg is doing a series of articles starting with Email system, and he has a special interest in authentication. There's also a series of articles, including group theory, by User:Richard Pinch, with topics that might tie to crypto algorithms. Howard C. Berkowitz 02:32, 25 November 2008 (UTC)

Hi Sandy. Thanks for your interest in my articles under Email System, and the link to PGP. I am the developer of ZCrypt, a little-known, but very secure secret-key system, so I have an interest also in cryptography. I appreciate also your link to the Global Trust Register. This has gotten me thinking about changing the title of my Registry of Internet Transmitters. Although email is the main application, it could be used with any application needing to establish trust in a TCP-based transaction on the Internet. David MacQuigg 13:59, 25 November 2008 (UTC)

I'm delighted to see this connection. While I can say I know a good deal about communications intelligence and information security, I don't pretend to be immersed in the details of modern cryptographic algorithms. If I can be more in the role of editing as one knowledgeable in the context and how a non-subspecialist would see the topics, that's more useful for everyone.

Me network engineer. Push bits and packets around. Some encrypted. Router not care unless in header; then link encryptor cares. Physical and electronic security — ah, those are equines of a different reflective wavelength. ;-) Howard C. Berkowitz 14:32, 25 November 2008 (UTC)

About approval of Brute force

Sandy, I have added my name to the Metadata template as an approval nominator for Brute force. However, I did ask you to create some of the subpages. Please have a look here. Milton Beychok 20:29, 26 March 2009 (UTC)

Please look at my response to your request for a review of the Bibliography and External links subpages. Sorry, I got held up in replying. But I think my response is a bit more clearly explained than Howard's. (Don't tell him I said so.)

For your info in the future, CZ:Citation templates has instructions on how to use a bunch of different citation templates. Regards, Milton Beychok 03:21, 27 March 2009 (UTC)

About reviewing or nominating other crypto articles

Sandy, in response to to your query on my Talk page this morning:

• Yes, I still support the approval nomination of Brute force attack and have said so on the article's Talk page.

• But I really cannot undertake reviewing or nominating any other crypto articles. Milton Beychok 15:10, 30 March 2009 (UTC)

Additional articles

I'm still going to be playing catchup for a few days. Just glanced at FreeSWAN -- it does have some rendering problems -- but my initial thought is that we should first work on Cypherpunk. I'm trying to understand the political context for FreeSWAN. I'm probably not explaining this very well, but I see several related things here: the OE article, the Cypherpunk movement, FreeSWAN saying essentially why Cypherpunk wanted to do OE and any criticism thereof (or should FreeSWAN fold into Cypherpunk?). Not to be forgotten is that I'd like to see reasonable cross-linking between these and IPSec, and maybe VPN. It would be nice if VPN unified my more provider orientation and your more end system one (or so I think is yours).

We also may want to get Dave McQuigg's thinking on this, and for that I have to get back to some material he's sent me for review. My logic here, which may be faulty, is that some of his secure email work might tie in. I'd like to find someone better on secure DNS than I am; the best explainer I know is Ugandan.

Please don't take this complexity as meaning it all has to happen at once. It doesn't, but I'd like to see a plan among a few of us. We just might be close to breakthrough on getting some outside computer visibility here; I have a couple of people in mind who might at least guest review--not that we really have a mechanism. I'll drop you an email as I don't want to name them without permission. Howard C. Berkowitz 01:29, 2 April 2009 (UTC)

New Draft of the Week - formatting test

Hi Sandy, I have been fiddling around with the formatting of the Article of the Week and New Draft of the Week and would be thankful if you would play the guinea pig (in terms of testing the documentation) by changing the formatting for the New Drafts. I have also asked Milt and Howard, so please do one article at a time. Thanks! --Daniel Mietchen 05:03, 7 June 2009 (UTC)

Finite fields

Hi. The article on finite fields is far from satisfactory. But what do you mean by "multiple types" of finite fields? Peter Schmitt 10:30, 5 August 2009 (UTC)

article approved

Hi, Sandy, I just finished approving your article, correctly, I hope! Hayford Peirce 19:24, 1 December 2009 (UTC)

Cryptography

Sandy, I have to apologize that I have not yet read the article. --Peter Schmitt 19:23, 27 April 2010 (UTC)

new member

Hi, Sandy, I've just approved a new Author named http://en.citizendium.org/wiki/User:James_R._McCarthy whose background and interests seem similar to yours. Cheers! Hayford Peirce 20:21, 3 May 2010 (UTC)

Hi Sandy, James here,yes some similar interests, and your also in China (what part? I'm in Jiangxi), Am I right in assuming that your interest in computer security and cryptography began after you moved to China?--James R. McCarthy 13:06, 4 May 2010 (UTC)

I'm currently in Fuzhou, likely move to Shanghai/Suzhou area next academic year. Your assumption is wrong; I was interested in this stuff long before moving here. Sandy Harris 15:36, 4 May 2010 (UTC)

Random generators

Hi Sandy. Your work is wonderful, but not close to my expertise. Your message is moved by me from Talk:Boris Tsirelson to User talk:Boris Tsirelson (and answered there). Boris Tsirelson 05:29, 9 May 2010 (UTC)

Cryp. article at [1] approved

Congratulations, Sandy, we've finally got your article approved! Sorry for the various delays.... Hayford Peirce 21:08, 26 May 2010 (UTC)

Kerckhoffs' Principle

Congratulations on another approval! (Thanks for the Howard bump ;) D. Matt Innis 14:42, 1 June 2010 (UTC)

Links in references

Sandy, could you check (and fix) the links in references 8, 12, 17, 18, 19 8, 14, 19, 20, 21? --Peter Schmitt 14:35, 19 June 2010 (UTC)

Claude Shannon article

Sandy, unless I misperceive, it appears that you have removed the sentence from Claude Shannon that stated that he worked at Bell Laboratories and that he suffered from Alzheimers late in life. Unless you have a major objection, I would like to restore that information to the article, as I believe both pieces of information to be worthly of mentioning in the broad overview of his life and work.Pat Palmer 20:50, 24 June 2010 (UTC)

Oops, sorry! I was looking at the diffs and didn't pay close enough attention. Thanks for the reply. Thanks also for the work you do here in CZ.Pat Palmer 15:06, 25 June 2010 (UTC)

Cryptanalysis

Hi, Sandy. Is now a good moment to resume Cryptanalysis approval?. I do not want to hurry you, of course. --Peter Schmitt 10:33, 10 July 2010 (UTC)

Up to you. I will not be around for at least a week, though. I'm in the process of packing, then move, then get set up at new place. Sandy Harris 12:22, 10 July 2010 (UTC)

Then it is better to wait. As you know, there are a few fixes that I cannot do if I want to approve it.

I sympathize with you ... moving is hard work. --Peter Schmitt 00:02, 13 July 2010 (UTC)

Moving is done & I've just got Internet service at new place. Sandy Harris 02:09, 24 July 2010 (UTC)

Sandy, if the remaining issues (broken links) are resolved I shall resume the postponed approval process. --Peter Schmitt 10:48, 27 July 2010 (UTC)

Homeopathy

Sandy, thank you for your contributions on Homeopathy. I appreciate your thought process and ability to state the obvious in a neutral fashion. Keep up the good work, please. D. Matt Innis 12:50, 15 September 2010 (UTC)

You've been Nominated!

Someone has nominated you for a position in the new Citizendium. They have noticed you're dedication to the project and like what they see. To be listed on the ballot for the position, it is necessary that you accept the nomination on the Nomination page. Just place accept next to your name along with the four tildes. The nomination period will close at midnight October 7 (UTC). Article 54 of the new charter details the requirements:

Article 54

• In conjunction with the Declaration of the Editor-in-Chief regarding the effectivity of this Charter, there shall be a call for nominations for the following offices: Managament Council (five seats), Editorial Council (seven seats), Managing Editor (one), Ombudsman (one). This shall be the effective date of the Charter.
• Any Citizen may nominate candidates for these positions.
• Nominations shall be collected and collated by the Chief Constable.
• Nominations shall be accepted no more than fourteen days after the effective date of the charter; the ballot shall be available starting on the twentieth day after the effective date of the charter; the election shall be completed no more than twenty-eight days after the effective date of the charter; all elected officials shall begin their term of office on the thirtieth day after the effective date of the charter.
• Only candidates who accept their nomination shall be eligible to appear on the ballot. Nominated candidates can accept nominations for no more than two official functions. Accepting a nomination serves as a declaration of commitment, in the case of being elected, to fulfill this function until the limit of the term.
• All positions shall be elected by a simple majority of the voting citizenry. In the case of a tie, an immediate run-off election shall be held.
• In the event that a candidate has been elected for two functions, the candidate shall declare which one he or she accepts within three days of announcement of the election results. In the event that such a declaration has not been made during this period, the candidate shall be considered elected for the position for which the nomination was accepted first. The same procedure applies to a reserve member that becomes elected by a seat being vacated this way.

If you would like to make a statement to help voters, click the "Statement" link to the right of your name.

Thanks again for the commitment you're making to assure that Citizendium becomes the premier quality online source we all have envisioned.

Godwin's Law

Please take a look at this, and revise and extend. Were you thinking of doing an EFF article? Howard C. Berkowitz 00:36, 5 October 2010 (UTC)

Homeopathy

Hi Sandy. I had a window today in which I could take a look at the article, and I've put an explanation on the Talk page of what I was doing in my edits. If you want my opinion on any specific point, ask - but feel confident that I trust your judgement.Gareth Leng 16:37, 5 October 2010 (UTC)
