# 01. Trust Anchor Locator (TAL)
|
||||
|
||||
## 1.1 对象定位
|
||||
TAL是一个数据格式/配置文件，目的是告诉RP信任锚的公钥是什么，以及相关对象可以从哪里获取。
|
||||
|
||||
## 1.2 数据格式 （RFC 8630 §2.2）
|
||||
TAL是一个配置文件，格式定义如下：
|
||||
```
|
||||
The TAL is an ordered sequence of:
|
||||
1. an optional comment section consisting of one or more lines each starting with the "#" character, followed by human-readable informational UTF-8 text, conforming to the restrictions defined
|
||||
in Section 2 of [RFC5198], and ending with a line break,
|
||||
2. a URI section that is comprised of one or more ordered lines, each containing a TA URI, and ending with a line break,
|
||||
3. a line break, and
|
||||
4. a subjectPublicKeyInfo [RFC5280] in DER format [X.509], encoded in base64 (see Section 4 of [RFC4648]). To avoid long lines,
|
||||
line breaks MAY be inserted into the base64-encoded string.
|
||||
Note that line breaks in this file can use either "<CRLF>" or "<LF>".
|
||||
```

# 2.4 TA校验流程（RFC 8630 §3）
|

1. 从TAL的URI列表中获取证书对象。（顺序访问，若前面失效，再访问后面的）
|
||||
2. 验证证书格式，必须是当前、有效的自签名RPKI证书。
|
||||
3. 验证公钥匹配。TAL中的SubjectPublicKeyInfo与下载证书的公钥一致。
|
||||
4. 其他检查。
|
||||
5. 更新本地存储库缓存。

# 05. RPKI Signed Object（CMS SignedData 外壳）
|
||||
|
||||
## 5.1 对象定位
|
||||
|
||||
ROA、Manifest 等都属于 “RPKI Signed Object”，其外壳是 CMS SignedData，并受 RFC 6488 的 profile 约束；RFC 9589 进一步更新了 `signedAttrs` 的要求。RFC 6488 §2-§4；RFC 9589 §4。
|
||||
|
||||
本文件描述**通用外壳模型**（eContentType/eContent 由具体对象文档给出）。
|
||||
|
||||
## 5.2 原始载体与编码
|
||||
|
||||
- 载体：CMS `ContentInfo`，其中 `contentType` 为 SignedData。RFC 6488 §2；RFC 6488 §3(1a)。
|
||||
- 编码：DER。RFC 6488 §2；RFC 6488 §3(1l)。
|
||||
|
||||
### 5.2.1 CMS 外壳：ContentInfo（ASN.1；RFC 5652 §3）
|
||||
|
||||
```asn1
|
||||
ContentInfo ::= SEQUENCE {
|
||||
contentType ContentType,
|
||||
content [0] EXPLICIT ANY DEFINED BY contentType }
|
||||
|
||||
ContentType ::= OBJECT IDENTIFIER
|
||||
```
|
||||
|
||||
### 5.2.2 CMS 外壳：SignedData（ASN.1；RFC 5652 §5.1）
|
||||
|
||||
```asn1
|
||||
id-signedData OBJECT IDENTIFIER ::= { iso(1) member-body(2)
|
||||
us(840) rsadsi(113549) pkcs(1) pkcs7(7) 2 }
|
||||
|
||||
SignedData ::= SEQUENCE {
|
||||
version CMSVersion,
|
||||
digestAlgorithms DigestAlgorithmIdentifiers,
|
||||
encapContentInfo EncapsulatedContentInfo,
|
||||
certificates [0] IMPLICIT CertificateSet OPTIONAL,
|
||||
crls [1] IMPLICIT RevocationInfoChoices OPTIONAL,
|
||||
signerInfos SignerInfos }
|
||||
|
||||
DigestAlgorithmIdentifiers ::= SET OF DigestAlgorithmIdentifier
|
||||
|
||||
SignerInfos ::= SET OF SignerInfo
|
||||
```
|
||||
|
||||
### 5.2.3 CMS 外壳：EncapsulatedContentInfo（ASN.1；RFC 5652 §5.2）
|
||||
|
||||
```asn1
|
||||
EncapsulatedContentInfo ::= SEQUENCE {
|
||||
eContentType ContentType,
|
||||
eContent [0] EXPLICIT OCTET STRING OPTIONAL }
|
||||
|
||||
ContentType ::= OBJECT IDENTIFIER
|
||||
```
|
||||
|
||||
> 注：CMS 允许 `eContent` 不一定 DER 编码（RFC 5652 §5.2）；但 RPKI signed object profile 要求**整个对象 DER 编码**（RFC 6488 §2；RFC 6488 §3(1l)），且 eContent（payload）由对象规范定义并通常为 DER（如 ROA：RFC 9582 §4；Manifest：RFC 9286 §4.2）。
|
||||
|
||||
### 5.2.4 CMS 外壳：SignerInfo 与 Attribute（ASN.1；RFC 5652 §5.3）
|
||||
|
||||
```asn1
|
||||
SignerInfo ::= SEQUENCE {
|
||||
version CMSVersion,
|
||||
sid SignerIdentifier,
|
||||
digestAlgorithm DigestAlgorithmIdentifier,
|
||||
signedAttrs [0] IMPLICIT SignedAttributes OPTIONAL,
|
||||
signatureAlgorithm SignatureAlgorithmIdentifier,
|
||||
signature SignatureValue,
|
||||
unsignedAttrs [1] IMPLICIT UnsignedAttributes OPTIONAL }
|
||||
|
||||
SignerIdentifier ::= CHOICE {
|
||||
issuerAndSerialNumber IssuerAndSerialNumber,
|
||||
subjectKeyIdentifier [0] SubjectKeyIdentifier }
|
||||
|
||||
SignedAttributes ::= SET SIZE (1..MAX) OF Attribute
|
||||
|
||||
UnsignedAttributes ::= SET SIZE (1..MAX) OF Attribute
|
||||
|
||||
Attribute ::= SEQUENCE {
|
||||
attrType OBJECT IDENTIFIER,
|
||||
attrValues SET OF AttributeValue }
|
||||
|
||||
AttributeValue ::= ANY
|
||||
|
||||
SignatureValue ::= OCTET STRING
|
||||
```
|
||||
|
||||
### 5.2.5 RPKI 对 CMS 外壳字段的 profile 约束（RFC 6488 §2.1；RFC 6488 §3；更新：RFC 9589 §4）
|
||||
|
||||
> 说明：上面是 CMS 的通用 ASN.1；RPKI 进一步约束取值与允许出现的字段（例如 SignedData.version 必须为 3、crls 必须省略、signedAttrs 的内容限制等）。RFC 6488 §2-§3；RFC 9589 §4。
|
||||
|
||||
### 5.2.6 signedAttrs 中允许的属性与 attrType OID（RFC 6488 §2.1.6.4.1-§2.1.6.4.2；更新：RFC 9589 §4）
|
||||
|
||||
RPKI signed object profile 对 `SignerInfo.signedAttrs` 的 Attribute 集合施加限制（除 ASN.1 结构外，还包含“只允许哪些 attrType”的编码约束）：
|
||||
|
||||
- `content-type`：attrType OID `1.2.840.113549.1.9.3`。RFC 6488 §2.1.6.4.1。
|
||||
- `message-digest`：attrType OID `1.2.840.113549.1.9.4`。RFC 6488 §2.1.6.4.2。
|
||||
- `signing-time`：attrType OID `1.2.840.113549.1.9.5`。RFC 9589 §4（更新 RFC 6488 的相关要求）。
|
||||
|
||||
并且：
|
||||
|
||||
- 每种属性在集合中只能出现一次；且 `attrValues` 虽然语法是 `SET OF`，但在 RPKI 中必须只含一个值。RFC 6488 §2.1.6.4。
|
||||
|
||||

# 06. Manifest（MFT）
|
||||
|
||||
## 6.1 对象定位
|
||||
|
||||
Manifest 是 CA 发布点内对象的“清单”（文件名 + hash），用于 RP 侧检测删除/替换/回放等不一致情况。RFC 9286 §1；RFC 9286 §6。
|
||||
|
||||
Manifest 是一种 RPKI Signed Object：CMS 外壳遵循 RFC 6488/9589，eContent 遵循 RFC 9286。RFC 9286 §4；RFC 6488 §4；RFC 9589 §4。
|
||||
|
||||
## 6.2 原始载体与编码
|
||||
|
||||
- 外壳：CMS SignedData DER（见 `05_signed_object_cms.md`）。RFC 9286 §4；RFC 6488 §2。
|
||||
- eContentType：`id-ct-rpkiManifest`，OID `1.2.840.113549.1.9.16.1.26`。RFC 9286 §4.1。
|
||||
- eContent：DER 编码 ASN.1 `Manifest`。RFC 9286 §4.2。
|
||||
|
||||
### 6.2.1 eContentType 与 eContent 的 ASN.1 定义（RFC 9286 §4.1；RFC 9286 §4.2）
|
||||
|
||||
Manifest 是一种 RPKI signed object（CMS 外壳见 `05_signed_object_cms.md`）。其 `eContentType` 与 `eContent` 的 ASN.1 由 RFC 9286 明确定义。RFC 9286 §4。
|
||||
|
||||
**eContentType（OID）**：RFC 9286 §4.1。
|
||||
|
||||
```asn1
|
||||
id-smime OBJECT IDENTIFIER ::= { iso(1) member-body(2) us(840)
|
||||
rsadsi(113549) pkcs(1) pkcs9(9) 16 }
|
||||
|
||||
id-ct OBJECT IDENTIFIER ::= { id-smime 1 }
|
||||
|
||||
id-ct-rpkiManifest OBJECT IDENTIFIER ::= { id-ct 26 }
|
||||
```
|
||||
|
||||
**eContent（Manifest 结构）**：RFC 9286 §4.2。
|
||||
|
||||
```asn1
|
||||
Manifest ::= SEQUENCE {
|
||||
version [0] INTEGER DEFAULT 0,
|
||||
manifestNumber INTEGER (0..MAX),
|
||||
thisUpdate GeneralizedTime,
|
||||
nextUpdate GeneralizedTime,
|
||||
fileHashAlg OBJECT IDENTIFIER,
|
||||
fileList SEQUENCE SIZE (0..MAX) OF FileAndHash
|
||||
}
|
||||
|
||||
FileAndHash ::= SEQUENCE {
|
||||
file IA5String,
|
||||
hash BIT STRING
|
||||
}
|
||||
```
|
||||
|
||||
解码要点：
|
||||
|
||||
- `fileHashAlg` 决定 `FileAndHash.hash` 的算法与输出长度（RPKI profile 要求 SHA-256）。RFC 9286 §4.2.1；RFC 7935 §2。
|
||||
- `hash` 在 ASN.1 中是 BIT STRING，但 hash 输出是按字节的比特串，DER 编码时应为 “unused bits = 0” 的 octet-aligned BIT STRING（实现可据此做一致性检查）。RFC 9286 §4.2。
|
||||
|
||||
## 6.3 解析规则（eContent 语义层）
|
||||
|
||||
输入：`RpkiSignedObject`。
|
||||

## 6.6 与 EE 证书的语义约束（为后续验证准备）
|
||||
|
||||
Manifest 使用“one-time-use EE certificate”进行签名验证，规范对该 EE 证书的使用方式给出约束：
|
||||
|
||||
- Manifest 相关 EE 证书应为 one-time-use（每次新 manifest 生成新密钥对/新 EE）。RFC 9286 §4（Section 4 前导段落）。
|
||||
- 用于验证 manifest 的 EE 证书 **MUST** 具有与 `thisUpdate..nextUpdate` 区间一致的有效期，以避免 CRL 无谓增长。RFC 9286 §4.2.1（manifestNumber 段落前的说明）。
|
||||
- 替换 manifest 时，CA 必须撤销旧 manifest 对应 EE 证书；且若新 manifest 早于旧 manifest 的 nextUpdate 发行，则 CA **MUST** 同时发行新 CRL 撤销旧 manifest EE。RFC 9286 §4.2.1（nextUpdate 段落末）；RFC 9286 §5.1（生成步骤）。

# 07. ROA（Route Origin Authorization）
|
||||
|
||||
## 7.1 对象定位
|
||||
|
||||
ROA 是一种 RPKI Signed Object，用于声明“某 AS 被授权起源某些前缀”。RFC 9582 §1；RFC 9582 §4。
|
||||
|
||||
ROA 由 CMS 外壳 + ROA eContent 组成：
|
||||
|
||||
- 外壳：RFC 6488（更新：RFC 9589）
|
||||
- eContent：RFC 9582
|
||||
|
||||
## 7.2 原始载体与编码
|
||||
|
||||
- 外壳：CMS SignedData DER（见 `05_signed_object_cms.md`）。RFC 9582 §1（引用 RFC 6488）。
|
||||
- eContentType：`id-ct-routeOriginAuthz`，OID `1.2.840.113549.1.9.16.1.24`。RFC 9582 §3。
|
||||
- eContent：DER 编码 ASN.1 `RouteOriginAttestation`。RFC 9582 §4。
|
||||
|
||||
### 7.2.1 eContentType 与 eContent 的 ASN.1 定义（RFC 9582 §3；RFC 9582 §4）
|
||||
|
||||
ROA 是一种 RPKI signed object（CMS 外壳见 `05_signed_object_cms.md`）。RFC 9582 定义了其 `eContentType` 以及 `eContent`（payload）的 ASN.1。RFC 9582 §3-§4。
|
||||
|
||||
**eContentType（OID）**：RFC 9582 §3。
|
||||
|
||||
```asn1

END
|

```
|
||||
|
||||
编码/解码要点（与上面 ASN.1 结构直接对应）：
|
||||
|
||||
- `addressFamily` 仅允许 IPv4/IPv6 两种 AFI，并且每个 AFI 最多出现一次。RFC 9582 §4.3.1。
|
||||
- `address` 是 BIT STRING 表示的前缀，语义与 RFC 3779 的 `IPAddress` 一致（按前缀长度截断，DER unused bits 置零）。RFC 9582 §4.3.2.1（引用 RFC 3779 §2.2.3.8）。
|
||||
- `maxLength` 为可选字段，出现与否会影响语义与编码规范约束（例如等于前缀长时不建议编码）。RFC 9582 §4.3.2.2。
|
||||
|
||||
## 7.3 解析规则（eContent 语义层）
|
||||
|
||||
输入：`RpkiSignedObject`。
|
||||
|
||||
1) 解析 CMS 外壳，得到 `econtent_type` 与 `econtent_der`。RFC 6488 §3；RFC 9589 §4。
|
||||
2) 要求 `econtent_type == 1.2.840.113549.1.9.16.1.24`。RFC 9582 §3。
|
||||
3) 将 `econtent_der` 以 DER 解析为 `RouteOriginAttestation` ASN.1。RFC 9582 §4。
|
||||
4) 将 `ipAddrBlocks` 解析为“前缀集合”的语义结构，并建议按 RFC 9582 给出的 canonicalization 过程做去重/排序/归一化（以便后续处理一致）。RFC 9582 §4.3.3。
|
||||

|
||||
|
||||
## 7.5 字段级约束清单（实现对照）
|
||||
|
||||
- eContentType 必须为 `id-ct-routeOriginAuthz`（OID `1.2.840.113549.1.9.16.1.24`），且该 OID 必须同时出现在 eContentType 与 signedAttrs.content-type。RFC 9582 §3（引用 RFC 6488）。
