# 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。

# 03. RC (Resource Certifications)
|
||||
|
||||
## 3.1 对象定位
|
||||
RC是资源证书，包括CA和EE
|
||||
|
||||
## 3.2 原始载体与编码
|
||||
|
||||
- 载体：X.509 certificates.
|
||||
- 编码：DER（遵循 RFC 5280 的 Certificate 结构与字段语义，但受 RPKI profile 限制）RFC 6487 §4
|
||||
|
||||
### 3.2.1 基本语法（RFC 5280 §4，RFC 6487 ）
|
||||
|
||||
RC是遵循RFC5280定义的X.509Certificate语法(RFC 5280 §4)，并且符合RFC 6487 §4的约束。只选取RFC 6487 §4章节列出来的字段。（Unless specifically noted as being OPTIONAL, all the fields listed
|
||||

|
||||
conforming resource certificate.）

||||
```

### 3.2.2 证书扩展字段 （RFC 6487 §4.8)
|
||||
|
||||
RC的证书扩展字段按照RFC 6487 §4.8的规定，有以下几个扩展：
|
||||
|
||||
- Basic Constraints
|
||||
- Subject Key Identifier
|
||||
- Authority Key Identifier
|
||||
- Key Usage
|
||||
- Extended Key Usage(CA证书，以及验证RPKI对象的EE证书不能出现该字段。非RPKI对象的EE可以出现EKU，但必须为non-critical)
|
||||
- CRL Distribution Points
|
||||
- Authority Information Access
|
||||
- Subject Information Access
|
||||
- SIA for CA Certificates
|
