PHYSICAL LAYER STEGANOGRAPHY METHOD AND SYSTEM

摘要: Disclosed are a physical layer steganography method and system, applied to the technical field of communications. In present embodiment, after signal sending end performs channel coding on carrier signal, an embedding for hidden in coded is determined according security level pre-set strategy; moreover, random sequence generated same indicate position signal; finally, embedded into so as obtain modulated sent out. Thus, during transmission view process, transmission, determines relatively secure that cannot be easily suspected by adverse monitoring end, improved.
