调研方向
该 issue 没有指出任何仓库文件或测试。先阅读 Let's Encrypt 的 CAA 参考资料和链接的 TEE-controlled domain certificates 设计，然后明确交付物应是已实现 CAA 方法的示例，还是对 encumbered DNS 的研究；形成有文档记录且达成一致的方法后即视为完成。
由索引模型根据 Issue 内容生成。
描述
There are a few ways of automating domain handling from within an enclave.
-
1. A starting point is the approach taken in teleport "trust but verify"...
The private key used to generate the certificate signing request is generated from within the enclave.
The owner of the DNS record isn't proactively prevented from issuing a non-TEE domain, but because certificate transparency provides a list of every issued certificate, we can show a remote attestation to explain every certificate that has been issued.
-
2. Another improvement is a DNS feature called CAA, https://letsencrypt.org/docs/caa/ which limits the CAs that are authorized to issue certificates for a domain. This significantly reduces the potential for rogue CAs to create MITM attacks - only letsencrypt could do that. This is what is implemented here https://docs.phala.network/dstack/design-documents/tee-controlled-domain-certificates
-
3. Encumbered DNS: a final step (still to research) would be to encumber the account with the registrar that owns the account. In this way, a smart contract would practically control the DNS records.
