Wireless communication networks are becoming increasingly popular, but they also pose security challenges due to the open nature of wireless transmissions. This article provides a comprehensive review of secure communication techniques in wireless networks, including their advantages, limitations, and future research avenues. The review covers various approaches, such as information-theoretic principles, power control, and malicious RISs.
Body
Secure Communication Techniques Based on Information-Theoretic Principles:
Information-theoretic principles have been widely used to secure wireless communication networks. These techniques ensure data security by preventing unauthorized interception and malicious use of private information without encryption methods. Power control is an essential aspect of these techniques, which ensures that the minimum amount of power required to achieve a specified confidentiality level is consumed over the transmission time.
PLS Methods
PLS (Precoding and Learning Security) methods refine transmission strategies and parameters, adapting to challenging channel conditions. PLS categorizes eavesdropping scenarios into passive and active, where passive eavesdroppers passively intercept transmissions without initiating active actions, while active eavesdroppers engage in both interception and adversarial activities.
Future Research Avenues
6.1 ML-Based Solutions
Machine learning (ML) techniques can be used to improve the security of wireless communication networks. ML algorithms can analyze data patterns and identify potential threats, enhancing the accuracy of secure communication systems.
Advanced RIS Types
Resistive islands (RISs) are being explored for their potential to enhance wireless communication security. Research is focusing on developing advanced types of RISs that can adapt to various channel conditions and improve the security of wireless communication networks.
Malicious RISs
Malicious RISs pose significant security threats to wireless communication networks. Research is being conducted to develop techniques for detecting and mitigating these threats, ensuring the secure operation of wireless communication systems.
Conclusion
Secure communication techniques are essential for protecting wireless communication networks from various threats. This article has provided a comprehensive review of secure communication techniques based on information-theoretic principles, PLS methods, and future research avenues. These techniques have shown promising results in ensuring the security of wireless communication networks, and further research is needed to overcome the limitations of these approaches and fully realize their potential.
