网络研讨会:KSK 轮转推迟和后续步骤讨论

洛杉矶——2017 年 10 月 4 日——互联网名称与数字地址分配机构 (Internet Corporation for Assigned Names and Numbers, ICANN) 于今天宣布主办一轮互动网络研讨会,题为"根区 KSK 轮转推迟:流程审视和后续步骤。"

本网络研讨会将由 ICANN 首席技术官办公室研究副总裁麦特·拉森 (Matt Larson) 负责主持。

另外,来自威瑞信公司 (Verisign, Inc.) 的著名工程师杜安·维塞尔 (Duane Wessels) 也将参加由拉森主持的研讨会,他还针对即将进行的根区 KSK 轮转一题搜集了解析器筹备情况的数据。

根区 KSK 是最为重要的密钥,保护着整个域名系统 (Domain Name System, DNS)。该密钥原预定在 2017 年 10 月 11 日进行变更,又称"轮转"。9 月 27 日,本组织宣布在分析了最新数据后,决定推迟轮转。新数据显示过多互联网服务提供商 (Internet Service Providers, ISP) 和网络运营商 (Network Operators) 并未对密钥更换做好准备,ICANN 因而不愿鲁莽变更密钥,因为此举可能会导致这些运营商的互联网终端用户无法连接上域名系统 (DNS)。


为了促进全球性参与,本次会议将提供以下语种的同声传译服务:阿拉伯语、中文、法语、葡萄牙语、俄语和西班牙语。参会人员将有机会在这节会议结束后提出自己的问题。在网络研讨会举行期间,参会人员还可以通过 Adobe Connect 系统的聊天功能提交问题。

在本轮网络研讨会召开之前,所有问题可提交至。我们将尽力在网络研讨会中答疑解惑,或在会后通过电子邮件的形式回复问题。请务必在 10 月 9 日星期一之前提交您的问题。




日期:2017 年 10 月 11 日

时间:世界协调时 15:00 至 16:00 时

Domain Name System
Internationalized Domain Name ,IDN,"IDNs are domain names that include characters used in the local representation of languages that are not written with the twenty-six letters of the basic Latin alphabet ""a-z"". An IDN can contain Latin letters with diacritical marks, as required by many European languages, or may consist of characters from non-Latin scripts such as Arabic or Chinese. Many languages also use other types of digits than the European ""0-9"". The basic Latin alphabet together with the European-Arabic digits are, for the purpose of domain names, termed ""ASCII characters"" (ASCII = American Standard Code for Information Interchange). These are also included in the broader range of ""Unicode characters"" that provides the basis for IDNs. The ""hostname rule"" requires that all domain names of the type under consideration here are stored in the DNS using only the ASCII characters listed above, with the one further addition of the hyphen ""-"". The Unicode form of an IDN therefore requires special encoding before it is entered into the DNS. The following terminology is used when distinguishing between these forms: A domain name consists of a series of ""labels"" (separated by ""dots""). The ASCII form of an IDN label is termed an ""A-label"". All operations defined in the DNS protocol use A-labels exclusively. The Unicode form, which a user expects to be displayed, is termed a ""U-label"". The difference may be illustrated with the Hindi word for ""test"" — परीका — appearing here as a U-label would (in the Devanagari script). A special form of ""ASCII compatible encoding"" (abbreviated ACE) is applied to this to produce the corresponding A-label: xn--11b5bs1di. A domain name that only includes ASCII letters, digits, and hyphens is termed an ""LDH label"". Although the definitions of A-labels and LDH-labels overlap, a name consisting exclusively of LDH labels, such as"""" is not an IDN."
