退化高斯窃听信道下极化码加密编码算法研究
Research on secure channel coding based on polarization code in degraded Gauss eavesdropping channel
摘要
Abstract
With the development of communication technology, the transmission security requirements from the system and user have also become more demanding.In this paper, a physical layer encryption security coding algorithm is proposed on the basis of a polarized code, in order to solve the physical layer security problem of a degraded Gauss eavesdropping channel.The algorithm divides the channel into a set of secure channels and a set of non-secure chan-nels .The information transmitted in the non-secure channels is encrypted by the information transmitted in the secure channel, and then encoded in order to achieve the safety and reliability of data transmission.The theoretical analysis and simulation results show that the proposed algorithm can guarantee reliable communication between legitimate us-ers, while preventing an eavesdropper from decoding data information;thereby, the reliability and safety of the com-munication system can be improved.Moreover, the proposed algorithm can effectively save channel resources and im-prove the channel utilization rate by sending information via the secure and non-secure channels.关键词
