## Factorization of Dual-Prime Composite Integers

A dual-prime composite, can be looked at as a rectangle with prime numbers as sides, 'P' & 'Q'. Allow that P > Q, if we can discover the value of P - Q, then the finding the factors of the composite is just trivial algebra. The simplest method of discovering the value of P - Q.

This 25 digit dual-prime composite, illustrates my point, I constructed it with the help of my telephone directory and a pin and using the nearest prime integer. You may need Windows Calculator to follow the protocol. First enter the dual-prime composite:-

2,612,064,319,773,176,994,885,077

I will skip the explanation as to how we deduce that the ratio of the two primes, is about 137/207. The method involves an algorithm and a test of 'squareness'. We know if the two primes 'P' and 'Q' form a rectangle of given proportions, a similar much smaller rectangle with the same proportions, when multiplied together, the product is pseudo-square.

We know that:- (P + Q)^2 = 4(P x Q) + (P - Q)^2,

2612064319773176994885077 x (137 x 207)

= 74075532044447526397945898643

The square root of that is:- 272168205425335.32015070563454555

So let's try 272168205425336...Nope! Try again 272168205425337...Nope! Try Again 272168205425338...EUREKA!

272168205425338 x 272168205425338 = 74075532044448985137492414244

And 74075532044448985137492414244 minus 74075532044447526397945898643 is equal to

1458739546515601

And the square root of that is exactly:- 38193449

272168205425338 - 38193449 = 272168167231889

272168167231889 / 137 = 1986628957897

2612064319773176994885077 / 1986628957897 = 1314822432941

1314822432941 & 1986628957897 The two prime factors.—Preceding unsigned comment added by Alastair Carnegie (talkcontribs) 20:07, 31 May 2009 (UTC)

This is well known as Fermat's factorization method. The method only works when P and Q have a small difference. For factoring RSA moduli it is therefore not suitable. Other methods such as the Number field sieve are much faster for breaking RSA keys. Btw, this discussion would be more suitable on Talk:RSA (i.e. the page discussing the algorithm) and not here (i.e. the page discussing the company that owned the RSA patent.) 92.106.113.28 (talk) 07:03, 1 June 2009 (UTC)

## Why are the external links removed?

Could someone please check this edit: [1] and explain why company URL and blog URL in the External Links section is treated as self promotion. Many other company pages have their company and blog URL in the external links. Please clarify. -- Countableinfinity (talk) 13:38, 5 March 2009 (UTC)

## Competitors

I'm just removing a list of competitors from this page. To be fair and unbiased we should either include competitors to all pages describing companies or leave them away. Including them is difficult and is hard to do without bias. Thus it is better to remove the list of competitors. 85.2.122.37 11:44, 13 April 2007 (UTC)

I meant it as a list of important companies manufacturing similar products. I think that this information is very important when you are looking for a certain solution which is produced by more companies. You can find similar links in other articles under See Also or Competitors like in the Check Point article (not added by me). I think that there are other much bigger differences among articles about companies which are neither fair nor unbiased.
Do you think that creating List of User Authentication Solution Manufacturers or List of User Authentication Solutions would be a better approach to solve this problem? --pabouk 12:44, 13 April 2007 (UTC)
Categories, would seem like the right way to go. Unfortunately, categories are often badly maintained in wikipedia. 85.2.122.37 16:34, 13 April 2007 (UTC)

## Data mining

This company knows a lot about individuals and there should be a way to opt out of these databases. I have learned some of the thinks this company knows about be by using etrade which uses them. Does any one know how to find out exactly what they know about someone. Something like a credit report. 98.197.243.41 04:33, 18 September 2007 (UTC)

## Fair use rationale for Image:RSA EMC logo highres.jpg

Image:RSA EMC logo highres.jpg is being used on this article. I notice the image page specifies that the image is being used under fair use but there is no explanation or rationale as to why its use in this Wikipedia article constitutes fair use. In addition to the boilerplate fair use template, you must also write out on the image description page a specific explanation or rationale for why using this image in each article is consistent with fair use.

Please go to the image description page and edit it to include a fair use rationale. Using one of the templates at Wikipedia:Fair use rationale guideline is an easy way to insure that your image is in compliance with Wikipedia policy, but remember that you must complete the template. Do not simply insert a blank template on an image page.

If there is other fair use media, consider checking that you have specified the fair use rationale on the other images used on this page. Note that any fair use images lacking such an explanation can be deleted one week after being tagged, as described on criteria for speedy deletion. If you have any questions please ask them at the Media copyright questions page. Thank you.

## RSA Australia

Interesting: http://www.columbia.edu/~ariel/cryptofud/openssl/msg00090.html Details the establishment of RSA Australia to avoid US crypto export laws. Could be detailed on the wiki page... Scuba (talk) —Preceding undated comment added 03:50, 28 August 2009 (UTC).

## RSA Security => RSA, The Security Division of EMC

• RSA SecurityRSA, The Security Division of EMC (move) – Hi, I'm an EMC/RSA employee reviewing our presence on Wikipedia. I suggest that the name of this page change to RSA, The Security Division of EMC. When EMC acquired the company in 2006, it became a division of EMC. Its official name is now RSA, The Security Division of EMC. In fact, this name is already noted in Wikipedia, above the quick facts box on the right side of this page and also in the first line of the page entry. I suggest the name of the page reflect the official name of the company, and that RSA Security redirect to the newly titled RSA, The Security Division of EMC. Socklessrebel (talk) 16:40, 12 October 2010 (UTC) Socklessrebel (talk) 16:40, 12 October 2010 (UTC)

This is an old request, but I'm inclined to agree with it. Our policy is to prefer common names over formal titles in general, but when a name must be disambiguated, a natural name is preferred over using parenthesis, as we have now. See WP:PRECISION. Comments?--agr (talk) 20:01, 24 April 2012 (UTC)

We generally favor natural disambiguation because it tends to be more elegant than the parenthetical type. This is a rare instance in which the opposite is true.
For related reasons, we also favor conventional English usage over special styling preferred by a trademark's owner. "RSA, The Security Division of EMC" is an unconventionally styled, slogan-like name. It receives fairly wide use in corporate documents (such as press releases and stock analysis), a context in which the owner's preference is honored indiscriminately (which we don't do). In general usage, simply "RSA" and even "RSA Security" (the former name) remain predominant. —David Levy 20:30, 24 April 2012 (UTC)
I don't see anything in WP:TRADEMARK that supports our current title. At most it might suggest "RSA Security, a division of EMC" as better matching English usage. Our guidelines say parenthetical is a last resort. I'd even prefer "RSA Security" over "RSA (security firm)," the latter being ugly and inaccurate, as RSA is no longer an independent firm.--agr (talk) 19:23, 25 April 2012 (UTC)
1. "RSA Security, a division of EMC" is neither the company's official name nor a name by which it's commonly known. "...editors should choose among styles already in use (not invent new ones)..."
2. In both that format and the one preferred by the company, the phrase set off by the comma is parenthetical in nature. That it doesn't include parentheses is immaterial; "RSA, The Security Division of EMC" is grammatically equivalent to (and no less ugly than) "RSA (The Security Division of EMC)".
As noted above, we generally prefer natural disambiguation because it typically is more elegant than appending "(disambiguation term)". In this instance, that simply isn't the case. When the logic behind a rule doesn't apply, we ignore it.
Suppose that the Iceland supermarket chain were to officially change its name to "Iceland, Your Source for the Highest Quality Frozen Foods Available". Would it then be desirable to move the article from Iceland (supermarket) to Iceland, Your Source for the Highest Quality Frozen Foods Available (on the basis that natural disambiguation is preferred)?
3. "Firm" is not inaccurate. Its definitions include "the name or title under which associated parties transact business" and "any commercial enterprise" (source). That RSA is no longer independent is irrelevant. —David Levy 20:16, 25 April 2012 (UTC)
1. I'm fine with the official name.
2. Parenthetical disambiguation is a special usage on Wikipedia that is used solely for dismbiguation, and one that is disfavored when a natural English title is available. And "RSA, The Security Division of EMC" is in no way compatible to "Iceland, Your Source for the Highest Quality Frozen Foods Available". The latter is puffery, the former is descriptive.
3. The general usage of "firm" implies an independent company. See e.g. http://www.thefreedictionary.com/business+firm There are no "divisions" in the many examples they give. But there is no need to split this hair when we have a title available that makes everything clear.
I think we ae at an impasse here. I'd like to invite a WP:third opinion.--agr (talk) 17:17, 27 April 2012 (UTC)
1. I'm not fine with the official name. It's inconsistent with conventional English ("The" instead of "the") and consists primarily of a slogan. (Appending a slogan to an official name doesn't make it cease to be one.)
2. Again, there's a reason why we usually disfavor parenthetical disambiguation when natural disambiguation is feasible: the latter typically is more elegant. We don't follow rules for the sake of following the rules.
You're entitled to disagree, but I don't believe that "RSA, The Security Division of EMC" (itself 85% parenthetical, I'll remind you) is more elegant than "RSA (security firm)" is. The slogan is descriptive, but so is "security firm". The former is part of a slick branding effort, while the latter is a common term used in ordinary speech and writing.
3. The word "independent" doesn't appear either, so I don't know why you believe that the absence of "division" constitutes evidence that "the general usage of 'firm' implies an independent company".
A Google search for the phrase "firm is a division" indicates otherwise. (See also: "firm is a subsidiary" and "firm is a wholly owned subsidiary")
I've cited dictionary definitions of "firm" under which RSA clearly falls (and your source provides similar ones). Reliable sources, such as The Wall Street Journal and BBC News, refer to RSA (under its current ownership) as a "security firm". I see absolutely no evidence corroborating your assertion that this is inaccurate/unusual. —David Levy 19:42, 27 April 2012 (UTC)
The name the organization has chosen for itself is merely descriptive, hardly slick. If you find the capitalized "The" offensive, we can make it lower case per WP:TRADEMARK. Ultimately, this is a judgement call, and hardly the most pressing of issues. I've list this on WP:3O to get another's viewpoint. --agr (talk) 22:07, 27 April 2012 (UTC)
The name the organization has chosen for itself is merely descriptive, hardly slick.
It's descriptive (as acknowledged above), but it isn't merely descriptive.
In no way did EMC's acquisition of RSA necessitate a name change. The division could have continued to operate as "RSA Security". "The Security Division of EMC" is a slogan used to advertise the parent company.
If you find the capitalized "The" offensive, we can make it lower case per WP:TRADEMARK.
That isn't the only issue. A Wikipedia article title's purpose is to identify the subject and distinguish it from others. In my view, "RSA (security firm)" best accomplishes that. "RSA, The Security Division of EMC", conversely, best supports the company's marketing efforts (hence an employee's visit to this page to request its use). That it's a "natural" form of disambiguation is a technicality with no meaningful significance to Wikipedia or its readers.
Ultimately, this is a judgement call, and hardly the most pressing of issues. I've list this on WP:3O to get another's viewpoint.
Fair enough. —David Levy 23:02, 27 April 2012 (UTC)
Note: I just repaired the WP:3O request by switching to a neutral description and removing your signature. —David Levy 01:22, 28 April 2012 (UTC)

──────────────────────────────────────────────────────────────────────────────────────────────────── Hey, guys, I'm here from the 3O board. I'd say that just disambiguating it as "RSA (EMC division)" or some such thing is the least awkward way of doing it. "The Security Divison of EMC" is just too long and really just beside the point. It's not so much that it's advertising, it's that it seems like a description more than a name, and titles just aren't supposed to be descriptive like that. It's just too cumbersome with that long phrase tacked on the end. I know that having something in parentheses is pretty cumbersome too, but at least we have some flexibility that way to improve it. Writ Keeper 03:29, 28 April 2012 (UTC)

I'm not sure that's enough of an improvement to warrant a change. In general, I prefer the terms in a parenthetical disambig be clear to a reader unfamiliar with the subject. I think its time to concede the argument to David and move on. Thanks for your help, though.--agr (talk) 09:35, 30 April 2012 (UTC)

## Blacklisted Links Found on the Main Page

Cyberbot II has detected that page contains external links that have either been globally or locally blacklisted. Links tend to be blacklisted because they have a history of being spammed, or are highly innappropriate for Wikipedia. This, however, doesn't necessaryily mean it's spam, or not a good link. If the link is a good link, you may wish to request whitelisting by going to the request page for whitelisting. If you feel the link being caught by the blacklist is a false positive, or no longer needed on the blacklist, you may request the regex be removed or altered at the blacklist request page. If the link is blacklisted globally and you feel the above applies you may request to whitelist it using the before mentioned request page, or request it's removal, or alteration, at the request page on meta. When requesting whitelisting, be sure to supply the link to be whitelisted and wrap the link in nowiki tags. The whitelisting process can take its time so once a request has been filled out, you may set the invisible parameter on the tag to true. Please be aware that the bot will replace removed tags, and will remove misplaced tags regularly.

Below is a list of links that were found on the main page:

Triggered by \bcbronline\.com\b on the local blacklist

From your friendly hard working bot.—cyberbot II NotifyOnline 15:47, 8 December 2013 (UTC)

Resolved This issue has been resolved, and I have therefore removed the tag, if not already done. No further action is necessary.—cyberbot II NotifyOnline 13:13, 20 December 2013 (UTC)

## Security company?

Currently in the article RSA is listed being "an American computer and network security company". How about we drop the security from this definition, as the company surely isn't about security at all? (Ref. December 20, 2013 backdoor for 10M$.) Usv (talk) 00:03, 21 December 2013 (UTC) I know this comment is ironic and/or sarcastic, but it raises a question I've had. How confident are we of the$10m figure cited by Reuters? They don't give their source; in particular, they don't attribute it to the Snowden leak compendium. Should we require more of a citation than a single unidentified source before including it in the article? Scryer (talk) 19:06, 22 December 2013 (UTC)
Fair point. I have at least reverted "revealed" to the less credulous "reported". PRRfan (talk) 05:29, 23 December 2013 (UTC)

How about we change their name to the more accurate 'NSA inSecurity' ? 87.50.51.170 (talk) 12:53, 22 December 2013 (UTC)
