| titleOfInvention | Polar code-based secure physical layer communication transmission method of wiretap channel |
| abstract | The invention discloses a pole code-based physical layer secret communication transmission method of a secret stealing channel, belonging to the field of communication. The invention sets up the structure of mixing up and mixing up in sending end and legal receiving end, to long polar code, design the chain type to encrypt the structure, the sending end stores information bit cipher key and freezing set information of the next frame into S of the current frame concentrates the preset position, except that every frame is mixed up and coded, encrypt and freeze set and replace between frame; for short polar codes, a two-dimensional confusion method is designed, continuous multiple frames are divided into a group, intra-frame confusion is firstly carried out on each frame in the group, inter-frame key position confusion is then carried out, intra-frame confusion is carried out for the second time, and then polar coding is carried out. The data transmission can be carried out on a group of short polar codes in combination with the chain encryption of long polar codes. The method of the invention improves the channel security and reduces the requirement on the degradation degree of the eavesdropping channel when the eavesdropper can not decode the eavesdropping channel at all. |
