γ约束均方误差下的无线信道加密方法
A Wireless Channel Encryption Method with γ Mean Square Error
摘要
Abstract
The design of secure wireless communication suffers a great challenge for openness of wireless channel and the broadcast nature of radio signals. The security problem introduced by wireless channel may be solved adequately by wireless channel itself. The space redundancy is often used in existing physical-layer security method to enhance security. So the concept of / mean square error is proposed in the paper, which is used to introduce redundancy for pre-coding weight. The concrete analysis and corresponding formal derivations are also given in the paper. Based on these, a novel physical-layer encryption method is proposed according to short-term reciprocity,rapid Decorrelation of wireless channel. Simulation results show that the proposed method guarantees wireless transmission in the authorized receiver and reduces the probability of interception.关键词
