➤ 從證書頒發機構的權力遊戲看現代網路信任危機
✤ https://blog.brycekerley.net/2026/03/08/webpki-and-you.html
本文深入探討網路公鑰基礎設施(WebPKI)的運作機制與其背後的政治與社會意義。作者指出,WebPKI 不僅僅是數據中心的硬體架構,更是一個由多方博弈、受利益驅動的複雜管理體系。文章透過梳理 HTTPS 的演進史,詳細解析了從證書核發、域名驗證(DV)到組織驗證(OV/EV)的流程,並揭示了在這個必須「信任」的系統中,當證書核發機構(CA)出現管理紕漏時,整個網路生態將面臨多大的風險。
+ 這篇文章把 WebPKI 的技術複雜度與社會政治層面連結得很棒,特別是提到 CA 與瀏覽器廠商之間的利益關係,這通常是技術文件中被忽略的部分。
+ 對於剛入門網路安全的人來說,這是很好的科普。但坦白說,看到 WebPKI 這種結構,依然會對現代網路的信任根基感到有些脆弱。

WebPKI and You
There’s been a push over the last twelve years to move web traffic off unencrypted HTTP to encrypted HTTPS, to protect the general public from dragnet surveillance, gaping assholes on public wifi>airpwn, backhauls over unencrypted satellites, that kinda thing. HTTPS relies on a public key infrastructure to make sure only authorized servers have keys for specific websites.
