摘要:

语义通信是下一代无线通信的重要参与者。通过这种新的范例,传统的物联网(IoT)正在向语义物联网(SIoT)发展,以实现显着的系统性能改进。然而,传统的用于比特传输的无线通信安全技术不能直接应用于专注于语义信息传输的SIoT。一个关键原因是缺乏新的安全业绩指标。因此,我们必须重新思考SIoT中的无线通信安全。因此,在本文中,我们分析和比较经典的安全技术,即,从语义信息安全的角度来看,物理层安全、隐蔽通信和加密。我们强调了这些安全技术在应用于SIoT时的差异。提出了新的性能指标,如语义保密中断概率(物理层安全技术)和检测失败概率(隐蔽通信技术)。考虑到语义通信可以提出新的安全问题,我们然后审查攻击和防御方法在语义水平。最后,我们提出了未来安全SIoT研究的几个有前途的方向。

英文摘要:

Semantic communication is an important participant in the next generation of wireless communications. Enabled by this novel paradigm, the conventional Internet-of-Things (IoT) is evolving toward the semantic IoT (SIoT) to achieve significant system performance improvements. However, traditional wireless communication security techniques for bit transmission cannot be applied directly to the SIoT that focuses on semantic information transmission. One key reason is the lack of new security performance indicators. Thus, we have to rethink the wireless communication security in the SIoT. As such, in the paper, we analyze and compare classical security techniques, i.e., physical layer security, covert communications, and encryption, from the perspective of semantic information security. We highlight the differences among these security techniques when applied to the SIoT. Novel performance indicators such as semantic secrecy outage probability (for physical layer security techniques) and detection failure probability (for covert communication techniques) are proposed. Considering that semantic communications can raise new security issues, we then review attack and defense methods at the semantic level. Finally, we present several promising directions for future secure SIoT research.
