1. Introduction

1. 介绍

This document introduces policy qualifiers in the certificate policies extension of the RPKI resource certificates. This document updates [RFC6487].

本文档介绍RPKI资源证书的证书策略扩展中的策略限定符。本文件更新了[RFC6487]。

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119].

本文件中的关键词“必须”、“不得”、“必需”、“应”、“不应”、“应”、“不应”、“建议”、“可”和“可选”应按照[RFC2119]中所述进行解释。

2. Update to RFC 6487

2. 更新至RFC6487

[RFC6487] profiles certificates, certificate revocation lists, and certificate signing requests specified in [RFC5280] for use in routing public key infrastructure.

[RFC6487]配置[RFC5280]中指定的用于路由公钥基础结构的证书、证书吊销列表和证书签名请求。

[RFC5280] defines an extension to certificates for the listing of policy information (see Section 4.2.1.4). [RFC6487] states in Section 4.8.9: "This extension MUST be present and MUST be marked critical. It MUST include exactly one policy, as specified in the RPKI CP [RFC6484]". This references the CertPolicyId of the sequence allowed in PolicyInformation as defined by [RFC5280].

[RFC5280]为策略信息列表定义证书扩展（见第4.2.1.4节）。[RFC6487]在第4.8.9节中指出：“此扩展必须存在，并且必须标记为关键。它必须包括RPKI CP[RFC6484]中规定的一个策略。”。这引用了[RFC5280]定义的PolicyInformation中允许的序列的CertPolicyId。

[RFC5280] also specifies that PolicyInformation may optionally have a sequence of PolicyQualifierInfo objects. [RFC6487] does not specifically allow or disallow these PolicyQualifierInfo objects, although Section 4 also states: "Unless specifically noted as being OPTIONAL, all the fields listed here MUST be present, and any other fields MUST NOT appear in a conforming resource certificate."

[RFC5280]还指定PolicyInformation可以选择性地具有PolicyQualifierInfo对象序列。[RFC6487]并未明确允许或禁止这些PolicyQualifierInfo对象，尽管第4节还规定：“除非特别注明为可选，否则此处列出的所有字段都必须存在，且任何其他字段不得出现在一致性资源证书中。”

Because there is a need for some RPKI Certificate Authorities to include policy qualifiers in their certificates, this document updates Section 4.8.9 of [RFC6487] as follows:

由于某些RPKI证书颁发机构需要在其证书中包含策略限定符，因此本文档将[RFC6487]的第4.8.9节更新如下：

OLD:

旧的：

This extension MUST be present and MUST be marked critical. It MUST include exactly one policy, as specified in the RPKI Certificate Policy (CP) [RFC6484].

此扩展必须存在并且必须标记为严重。它必须包括RPKI证书策略（CP）[RFC6484]中指定的一个策略。

NEW:

新的：

This extension MUST be present and MUST be marked critical. It MUST include exactly one policy, as specified in the RPKI CP [RFC6484]. Exactly one policy qualifier MAY be included. If a policy qualifier is included, the policyQualifierId MUST be the Certification Practice Statement (CPS) pointer qualifier type (id-qt-cps).

此扩展必须存在并且必须标记为严重。它必须包括RPKI CP[RFC6484]中指定的一个策略。只能包含一个策略限定符。如果包含策略限定符，则policyQualifierId必须是认证实践语句（CPS）指针限定符类型（id qt CPS）。

As noted in [RFC5280], Section 4.2.1.4: "Optional qualifiers, which MAY be present, are not expected to change the definition of the policy." In this case, any optional policy qualifier that MAY be present in a resource certificate MUST NOT change the definition of the RPKI CP [RFC6484].

如[RFC5280]第4.2.1.4节所述：“可能存在的可选限定符预计不会更改策略的定义。”在这种情况下，资源证书中可能存在的任何可选策略限定符不得更改RPKI CP[RFC6484]的定义。

3. Security Considerations

3. 安全考虑

The Security Considerations of [RFC6487] apply to this document.

[RFC6487]的安全注意事项适用于本文件。

This document updates the RPKI certificate profile to specify that the certificate policies extension can include a policy qualifier, which is a URI. While dereferencing the URI is not required for certificate validation, doing so could provide a denial-of-service (DoS) vector, where the target host may be subjected to bogus work dereferencing the URI. However, this specification, like [RFC5280], places no processing requirements on the URI included in the qualifier.

本文档更新RPKI证书配置文件，以指定证书策略扩展可以包括策略限定符，即URI。虽然证书验证不需要取消对URI的引用，但这样做可能会提供拒绝服务（DoS）向量，其中目标主机可能会遇到取消对URI引用的虚假工作。但是，与[RFC5280]一样，此规范对限定符中包含的URI没有处理要求。

As an update to [RFC6487], this document broadens the class of certificates that conform to the RPKI profile by explicitly including within the profile those certificates that contain a policy qualifier as described here. A relying party that performs a strict validation based on [RFC6487] and fails to support the updates described in this document would incorrectly invalidate RPKI objects that include the changes in Section 2.

作为对[RFC6487]的更新，本文档扩展了符合RPKI配置文件的证书类别，方法是在配置文件中明确包含包含策略限定符的证书，如下所述。依赖方根据[RFC6487]执行严格验证，且未能支持本文档中描述的更新，将错误地使包含第2节中更改的RPKI对象无效。

4. 致谢

Frank Hill and Adam Guyot helped define the scope of the issue covered by this document and identified and worked with RPKI validator implementers to clarify the use of policy qualifiers in resource certificates.

Frank Hill和Adam Guyot帮助定义了本文档涵盖的问题的范围，并确定了RPKI验证器实现者，并与他们合作，以澄清资源证书中策略限定符的使用。

Sean Turner provided significant text to this document regarding the processing of the CPS URI and limiting the scope of the allowable content of the policy qualifier.

Sean Turner为此文档提供了关于CPS URI处理和限制策略限定符允许内容范围的重要文本。
