在数字化浪潮奔涌的城市阡陌间，一块块亮起的公共显示屏既是传递资讯的"窗口"，也极易成为网络攻 击的"靶心"。面对公共屏幕点多面广、防护脆弱的现实痛点，如何给这些散落在街头的"信息孤岛"穿上 一层攻不破的"铠甲"？ 近日，梅林街道交出了一份硬核答卷。 该街道积极响应网络安全管理要求，破局立新，在全区率先引 入"AI大脑"与"量子盾牌"，构建起一套跨领域、全天候的公共显示屏监管体系，让信息安全管理从被动 防御迈向了"智能化、规范化、全域化"的硬核新阶段。 随着城市数字化进程的加速，公共电子显示屏已成为政策宣传、信息传播和商业推广不可或缺的重要载 体。然而，内容发布管理的分散化使得这些显示屏面临网络攻击、非法信息插播等严峻安全挑战。 尤为引人注目的是，该方案创新性采用了量子加密技术保障信息传输安全。 量子密钥的"真随机性"基于量子不可分割、无法精确克隆的物理原理生成，从根本上杜绝了密钥被预测 或复制的可能性。 在实际应用中，采用"量子真随机密钥 + 国密/传统加密算法"的复合模式，将物理层的绝对随机性与算 法层的强度紧密结合，实现了极高安全等级的加密效果。 此次监管体系升级实现了三大显著突破：一是覆盖范围实现跨行业 ...
