An Empirically Validated, Resilient SDR‐Based CubeSat Communication Architecture Featuring Dynamic AES‐256 and Deterministic Frequency Hopping
CubeSats are widely used in low‐cost space missions, but their dependence on commercial off‐the‐shelf (COTS) components and limited onboard resources creates security challenges for telemetry, command, and mission‐data links. This study presents a Software‐Defined Radio (SDR)‐based secure communication architecture e...
