嗯，用户让我用中文总结一篇文章，控制在100字以内，而且不需要特定的开头。首先，我得仔细阅读文章内容，理解主要信息。 文章讲的是在TLS握手过程中，服务器发送证书链以供客户端验证身份。引入后量子安全签名后，证书变大，导致握手过程变慢。IETF的PLANTS组提出使用Merkle树证书来解决这个问题。Google和Cloudflare已经开始测试这种方法，并提供了相关博客链接。同时建议测试TLS拦截防火墙和代理，以避免问题。 接下来，我需要将这些信息浓缩到100字以内。要抓住关键点：TLS握手、证书变大、Merkle树证书、Google和Cloudflare测试、建议测试防火墙和代理。 可能的结构是：介绍问题，解决方案，测试情况和建议。确保语言简洁明了，不使用复杂的术语。 最后检查字数是否符合要求，并确保信息准确无误。 </think> 在TLS握手过程中，服务器发送证书链供客户端验证身份。引入后量子安全签名使证书变大，导致握手过程变慢。IETF的PLANTS组提出使用Merkle树证书解决此问题。Google和Cloudflare已开始测试该方法，并建议测试TLS拦截防火墙和代理以避免问题。 2026-3-2 15:40:59 Author: www.reddit.com(查看原文) 阅读量:3 收藏
For those that don't know, during the TLS handshake, the server sends its certificate chain so the client can verify they're talking to who they think they are. When we move to Post Quantum-safe signatures for these certificates, they get huge and will cause the handshake to get really big. The PLANTS group at the IETF is working on a method to avoid this, and Merkle Tree Certificates are currently the way they're going.
Google and Cloudflare are going to start testing this (with proper safeguards in place) for traffic using Chrome and talking to certain sites hosted on Cloudflare. Announcements and explanations of MTC:

It might be a good time to test your TLS intercepting firewalls and proxies to make sure this doesn't break things for the time being. It's early days and a great time to get ahead of any problems.
