信息理论方法的安全性已经被检查作为一个有希望的补充，目前的密码技术。这种信息理论方法直接在通信网络的物理层建立可靠的通信和数据机密性，考虑到噪声信道的特性，从而在不考虑窃听者的计算能力的情况下实现无条件的安全。提供准确的信道状态信息是一个主要的挑战，特别是在无线通信系统中，特别是向窃听者提供有关信道的信息。此外，可能会有恶意的对手干扰或影响合法用户的通道。本文研究了信道不确定性和对抗性攻击下的不同安全通信模型，并回顾了相应的保密容量结果，这些结果表征了信息可以发送到合法接收者的最大速率，同时保持对窃听者的完全安全。
Information theoretic approaches to security have been examined as a promising complement to current cryptographic techniques. Such information theoretic approaches establish reliable communication and data confidentiality directly at the physical layer of a communication network by taking the properties of the noisy channel into account leading to unconditional security regardless of the computational capabilities of eavesdroppers. The provision of accurate channel state information is a major challenge particularly in wireless communication systems, especially information about the channels to eavesdroppers. In addition, there might be malevolent adversaries who jam or influence the channel of the legitimate users. This paper surveys different models for secure communication under channel uncertainty and adversarial attacks and reviews the corresponding secrecy capacity results, which characterize the maximum rate at which information can be sent to legitimate receivers while being kept perfectly security from eavesdroppers.
