Two-hop multi-relay network secure transmission method based on energy collection

The invention discloses a two-hop multi-relay network secure transmission method based on energy collection. Private information and interference information are transmitted; the relay Ri and the relay Rj receive transmitted interference information energy by adopting an energy harvesting mechanism harvesting part; a relay Ri forwards private information and interference information by adopting anamplifying and forwarding relay protocol, a relay Rj sends new interference information by adopting a decoding and forwarding scheme, a receiving end and an eavesdropping end both receive relay transmission information, the influence of interference on legal users is eliminated by designing the interference information, and safe transmission of the private information of a source node is completed. By adopting the method, the energy efficiency of the network is improved, and the relay working time is prolonged. 本发明公开了一种基于能量收集的两跳多中继网络安全传输方法，传输私密信息和干扰信息；中继R和R采用能量收割机制收割部分接收传输的干扰信息能量，中继R采用放大转发中继协议转发私密信息和干扰信息，中继R采用解码转发方案发
