One way to spoof nicknames is to simply add one or more space characters at the end, because the spaces don't show up in the interface (thus "stpeter", "stpeter " with one space at the end, and "stpeter " with two spaces at the end would all appear to be the same person). This seems like an obvious hole that we can plug by disallowing trailing (and perhaps leading) spaces in nicknames.

Ask, and ye shall receive. ### For comparison purposes (e.g., when a chatroom server determines if two nicknames are in conflict during the authorization process), an application MUST treat a nickname as follows, where the operations specified MUST be completed in the order shown (in particular, normalization MUST be performed before all other mapping steps and validity checks, consistent with [I-D.ietf-precis-framework]): 1. The string MUST be normalized using Unicode Normalization Form KC (NFKC). Because NFKC is more "aggressive" in finding matches than other normalization forms (in the terminology of Unicode, it performs both canonical and compatibility decomposition before recomposing code points), this rule helps to reduce the possibility of confusion by increasing the number of characters that would match (e.g., U+2163 ROMAN NUMERAL FOUR would match the combination of U+0049 LATIN CAPITAL LETTER I and U+0056 LATIN CAPITAL LETTER V). 2. Uppercase and titlecase characters MUST be mapped to their lowercase equivalents. In applications that prohibit conflicting nicknames, this rule helps to reduce the possibility of confusion by ensuring that nicknames differing only by case (e.g., "stpeter" vs. "StPeter") would not be allowed in a chatroom at the same time. 3. Non-ASCII space characters from the "N" category defined under Section 6.14 of [I-D.ietf-precis-framework] MUST be mapped to U+0020 SPACE. 4. Leading and trailing whitespace (i.e., one or more instances of the ASCII space character at the beginning or end of a nickname) MUST be removed (e.g., "stpeter " is mapped to "stpeter"). 5. Interior sequences of more than one ASCII space character MUST be mapped to a single ASCII space character (e.g., "St Peter" is mapped to "St Peter"). 6. Other mappings MAY be applied, such as those defined in [I-D.yoneya-precis-mappings]. (Note that mapping of fullwidth and halfwidth characters to their decomposition mappings is not necessary, since those mappings are performed as part of normalization using NFKC.) ### -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.18 (Darwin) Comment: Using GnuPG with Mozilla - http://www.enigmail.net/ iEYEARECAAYFAlCUe+8ACgkQNL8k5A2w/vxtIQCfTmw9qGRB1eFr9QbtMp9zbcQK jvsAn29QA3MmLc+JCwHwFBPaHFgKeE/E =wDpz -----END PGP SIGNATURE----- From marc.blanchet@viagenie.ca Sat Nov 3 16:23:04 2012 Return-Path: X-Original-To: precis@ietfa.amsl.com Delivered-To: precis@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 0C2D821F9C43 for ; Sat, 3 Nov 2012 16:23:04 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -101.942 X-Spam-Level: X-Spam-Status: No, score=-101.942 tagged_above=-999 required=5 tests=[AWL=0.658, BAYES_00=-2.599, NO_RELAYS=-0.001, USER_IN_WHITELIST=-100] Received: from mail.ietf.org ([64.170.98.30]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id 3q7EWBe38T3v for ; Sat, 3 Nov 2012 16:23:03 -0700 (PDT) Received: from jazz.viagenie.ca (jazz.viagenie.ca [IPv6:2620:0:230:8000::2]) by ietfa.amsl.com (Postfix) with ESMTP id A564021F9C3E for ; Sat, 3 Nov 2012 16:23:03 -0700 (PDT) Received: from [IPv6:2001:df8::64:e05e:a88d:5ad3:608b] (unknown [IPv6:2001:df8:0:64:e05e:a88d:5ad3:608b]) by jazz.viagenie.ca (Postfix) with ESMTPSA id E9D53467B6 for ; Sat, 3 Nov 2012 19:23:02 -0400 (EDT) From: Marc Blanchet Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: quoted-printable Date: Sat, 3 Nov 2012 18:39:14 -0400 Message-Id: To: precis@ietf.org Mime-Version: 1.0 (Apple Message framework v1283) X-Mailer: Apple Mail (2.1283) Subject: [precis] minute taker volunteers X-BeenThere: precis@ietf.org X-Mailman-Version: 2.1.12 Precedence: list List-Id: Preparation and Comparison of Internationalized Strings List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sat, 03 Nov 2012 23:23:04 -0000 Hello, we would use the wg ether pad for minute taking.

I think we should also add the confusable mapping (see: http://www.unicode.org/reports/tr39/#Confusable_Detection) here. This brings up another point, however. I think that things that are acting as registries (such as a chat server ensuring that there aren't two people using the same nickname) MUST NOT transmit these liberally-normalized names. That means they probably have to keep at least two (and maybe three) versions around: - The pr=E9cis-mapped version for equality checking - The confusable-mapped version for uniqueness checking - The original version (maybe, if the pr=E9cis-mapped version is losing information) This way, the spaces would still exist, but they aren't an attack vector. --=20 Joe Hildebrand From marc.blanchet@viagenie.ca Tue Nov 6 12:55:40 2012 Return-Path: X-Original-To: precis@ietfa.amsl.com Delivered-To: precis@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 0B55321F8AF3 for ; Tue, 6 Nov 2012 12:55:40 -0800 (PST) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -102.483 X-Spam-Level: X-Spam-Status: No, score=-102.483 tagged_above=-999 required=5 tests=[AWL=0.116, BAYES_00=-2.599, USER_IN_WHITELIST=-100] Received: from mail.ietf.org ([64.170.98.30]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id NLZ9pdJWnNkk for ; Tue, 6 Nov 2012 12:55:39 -0800 (PST) Received: from jazz.viagenie.ca (jazz.viagenie.ca [IPv6:2620:0:230:8000::2]) by ietfa.amsl.com (Postfix) with ESMTP id 9439C21F85D8 for ; Tue, 6 Nov 2012 12:55:39 -0800 (PST) Received: from dhcp-5059.meeting.ietf.org (dhcp-5059.meeting.ietf.org [130.129.80.89]) by jazz.viagenie.ca (Postfix) with ESMTPSA id D7DFA414AD for ; Tue, 6 Nov 2012 15:55:38 -0500 (EST) From: Marc Blanchet Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: quoted-printable Date: Tue, 6 Nov 2012 15:55:37 -0500 Message-Id: <288A1AE8-D308-40A5-99EE-ECE36F573A37@viagenie.ca> To: precis@ietf.org Mime-Version: 1.0 (Apple Message framework v1283) X-Mailer: Apple Mail (2.1283) Subject: [precis] IETF85 precis meeting minutes X-BeenThere: precis@ietf.org X-Mailman-Version: 2.1.12 Precedence: list List-Id: Preparation and Comparison of Internationalized Strings List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 06 Nov 2012 20:55:40 -0000 hello, thanks to Matt and others who contributed, please find the IETF85 = precis meeting minutes at:=20 http://www.ietf.org/proceedings/85/minutes/minutes-85-precis Please send corrections to the chairs (precis-chairs@tools.ietf.org) Regards, Marc&Yoneya-san= From stpeter@stpeter.im Tue Nov 6 20:48:56 2012 Return-Path: X-Original-To: precis@ietfa.amsl.com Delivered-To: precis@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 3EB2D21F8BD9 for ; Tue, 6 Nov 2012 20:48:56 -0800 (PST) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -103.599 X-Spam-Level: X-Spam-Status: No, score=-103.599 tagged_above=-999 required=5 tests=[AWL=1.000, BAYES_00=-2.599, GB_I_LETTER=-2, USER_IN_WHITELIST=-100] Received: from mail.ietf.org ([64.170.98.30]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id 0ZCGiZWQNKtp for ; Tue, 6 Nov 2012 20:48:55 -0800 (PST) Received: from stpeter.im (mailhost.stpeter.im [207.210.219.225]) by ietfa.amsl.com (Postfix) with ESMTP id 4A38821F8BD2 for ; Tue, 6 Nov 2012 20:48:55 -0800 (PST) Received: from [10.0.0.74] (unknown [50.73.80.245]) (Authenticated sender: stpeter) by stpeter.im (Postfix) with ESMTPSA id 2BB994010C; Tue, 6 Nov 2012 21:52:38 -0700 (MST) Message-ID: <5099E833.6030808@stpeter.im> Date: Tue, 06 Nov 2012 23:48:51 -0500 From: Peter Saint-Andre User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:16.0) Gecko/20121026 Thunderbird/16.0.2 MIME-Version: 1.0 To: "Joe Hildebrand (jhildebr)" References: In-Reply-To: X-Enigmail-Version: 1.4.5 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 7bit Cc: "precis@ietf.org" Subject: Re: [precis] spaces at end of nickname X-BeenThere: precis@ietf.org X-Mailman-Version: 2.1.12 Precedence: list List-Id: Preparation and Comparison of Internationalized Strings List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 07 Nov 2012 04:48:56 -0000 -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 On 11/6/12 6:51 AM, Joe Hildebrand (jhildebr) wrote: > On 11/2/12 8:05 PM, "Peter Saint-Andre" > wrote: > >> Ask, and ye shall receive. >> >> ### >> >> For comparison purposes (e.g., when a chatroom server determines >> if two nicknames are in conflict during the authorization >> process), an application MUST treat a nickname as follows, where >> the operations specified MUST be completed in the order shown (in >> particular, normalization MUST be performed before all other >> mapping steps and validity checks, consistent with >> [I-D.ietf-precis-framework]): >> >> 1.
