=== ## === 原因: * 使用真实网站证书链 * TLS handshake 100% 模拟 Chrome/Safari * SNI 为真实网站 * 没有固定端口、协议特征 * 探测者如果封了 Reality 就会误伤大量真实网站 DPI 无法区分: “这是访问 Google/CDN” 还是 “这是 Reality 代理握手” 👉 封 Reality 的成本 > 好处,因此难封。 ==== SS 多年来被针对性研究非常多: ==== * 流量特征已知 * AEAD 加密虽安全但不等于流量像 HTTPS * 一些实现会暴露模式特征(如包长度分布) 新一代 SS(2022、短连接、Padding、随机化)已改善,但: 👉 SS 仍然是“加密代理”,不是“伪装成 HTTPS” 所以理论上还是可探测的。 ==== 因为: ==== * UDP/QUIC 结构明显 * 传输层特征清晰 * 包长度分布与一般网页浏览差异很大 * 较少伪装机制 而且 HY2 的速度太极端,在 DPI 眼里就像: : 👉 封锁风险最大,但速度最强。
