摘要:
针对两用户协作通信系统的身份认证问题,提出了一种基于正交幅度调制( QAM) 的协作物理层认证机 制。 在该机制中,两个单天线用户分别使用同相与正交分量传输自己及伙伴的消息和标签,从而实现两用户消息 和标签的唯一分解。 基站采用最大比合并检测用户消息和标签,并通过标签对比完成物理层身份认证。 在等功率 分配且用户上行信道对称的典型场景下,给出了消息和标签的误码率闭合表达式。 结果表明:在信噪比( SNR) 为 6 ~ 15 dB 时,所提机制的认证概率与非协作物理层认证相比提高了 12% ~ 20%,非法攻击认证概率仅保持在 10 - 3 量 级,所提认证机制具有更好的身份认证性能。
Abstract:
A quadrature amplitude modulation (QAM) based cooperative physical layer authentication mechanism was proposed for the identity authentication in two-user cooperative communication systems. In the proposed mechanism, two single-antenna users transmitted their own messages and tags as well as those of the partner with the inphase component and orthogonal component, respectively. Thus, the messages and tags of two users could be uniquely decomposed. Maximal ratio combining was employed at the base station to detect the messages and tags, and physical layer identity authentication was performed through tag comparison. In a typical scenario with equal power distribution and symmetric user uplink channels, the closed expressions of symbol error rates of message and tag were derived. The simulation results showed that the authentication probability of the proposed mechanism was improved by 12% - 20% compared with the non-cooperative physical layer authentication when the signal-to-noise ratio ( SNR) was 6-15 dB. Meanwhile, the authentication probability of illegal attack remained only around 10 - 3 . Consequently, the proposed mechanism had better authentication performance
