TID-The-Instant-Destroyer

TID — 即时销毁器 针对基于缓存的旁路攻击防护领域的独立安全研究。 概述 TID 是一种专用协议，旨在在使用后立即从 CPU 缓存层（$L1、L2$ 和 $L3$）中消除敏感数据残留（例如加密密钥）。它解决了数据在系统内存（RAM）中被擦除后仍存在于硬件结构中的关键安全漏洞。 主要成就 已验证的防御： 有效缓解 Flush+Reload 及类似的微架构旁路攻击。 可衡量的性能： 未受保护的访问： 78 CPU 周期（缓存命中）。 TID 保护的访问： 286 CPU 周期（缓存未命中）。 安全边际： 提供 3.7 倍延迟屏障 ，成功迷惑潜在攻击者。 硬件级精度： 利用优化的 CPU...
