Authentication is the process of confirming the legal identity of communicating entities, and it is the first line of defense for security communication. Most of the existing tag-based physical layer security authentication (PLSA) requires distributing the shared keys in advance. In the large scale internet of things scenario, nodes frequently join and leave the wireless networks that cause the distribution and management of keys particularly difficult. This paper proposes a tag-based PLSA scheme, which utilizes channel characteristics instead of distributing keys to generate authentication tags. Specifically, based on watermarking mechanism, we design a fault-tolerant hash algorithm to couple the secret sequence and the message signal for authentication tags generation. The shared secret sequence is generated by legitimate nodes through channel probing. And the theories of information theory and composite hypothesis testing is employed to analyze the performance of system. The simulation results show that the agreement ratio of the generating shared secret sequence is as high as 96% in the case of high signal-to-noise ratio and low power tag embedding. In addition, performance analysis demonstrates the scheme can resist against multiple attacks, such as replay, jamming, tampering, and impersonation attack.

一种无需密钥分发的基于标签的 PHY 层认证方案
认证是确认通信实体合法身份的过程,是安全通信的第一道防线。大多数现有的基于标签的物理层安全认证(PLSA)需要预先分发共享密钥。在大规模物联网场景中,节点频繁加入和离开无线网络,使得密钥的分发和管理变得尤为困难。本文提出了一种基于标签的PLSA方案,它利用信道特性而不是分发密钥来生成认证标签。具体来说,基于水印机制,我们设计了一种容错哈希算法来耦合秘密序列和消息信号以生成认证标签。共享秘密序列由合法节点通过信道探测生成。并运用信息论和复合假设检验理论对系统性能进行分析。仿真结果表明,在高信噪比和低功率标签嵌入的情况下,生成的共享秘密序列的一致率高达96%。此外,性能分析表明该方案可以抵抗重放、干扰、篡改和冒充攻击等多种攻击。
