射頻 / SDR 安全研究

用於授權的 RF/SDR 安全研究，包括在屏蔽實驗室中進行訊號識別、重放可行性研究，以及經典 Wi-Fi 之外的無線協定分析。

SDR 安全研究 是什麼？

這個技能專注於射頻 (RF) 與軟體定義無線電 (SDR) 安全研究，主要應用於授權環境。它強調法規合規性，明確規定預設僅進行接收，避免干擾公共通訊。此技能支援分析非 Wi-Fi 的無線訊號（如遙控器、感測器、ADS-B），並可搭配 RTL-SDR、HackRF 等硬體，以及 URH、GNU Radio、Inspectrum 等軟體工具進行訊號識別、解調與協議分析。雖然進階的重放測試僅限於屏蔽實驗室且需書面授權，但技能的核心價值在於幫助安全研究人員透過安全、可控的方式評估無線通訊的安全性，並提供具體的加固建議。它與其他專注於 Wi-Fi 攻防（如 wifi-wireless）或 OT/ICS 安全的技能明確分工，能獨立或協同完成更廣泛的物聯網與嵌入式安全評估。

RF / SDR 安全研究

行動要求（讀完後立刻執行）

  1. NOW：頻譜與發射受法律嚴格管制；僅限授權頻段 / 屏蔽室 / 實驗目標
  2. NOW：scope 需寫明設備、頻段、是否允許發射（預設僅接收）
  3. ACT：僅接收識別 → 解調分析 → 實驗室復現評估

適用場景

  • 無線遙控 / 感測器等非 Wi-Fi RF（授權）
  • ADS-B / 遙控等協定研究（合法接收）
  • 與 wifi-wireless 分工：本技能偏 SDR 通用 RF；Wi-Fi 攻防請走 R29

工作流程

□ 法規與許可確認
□ 僅接收：識別中心頻率與調變
□ GNU Radio / URH 分析
□ 重放僅在屏蔽室且書面允許
□ 結論側重：是否可未授權控制 / 加固建議

工具鏈

工具用途
RTL-SDR / HackRF（合規）收發硬體
URH / GNU Radio分析
Inspectrum訊號
