本文使用轨道角动量（OAM）波在0.31THZ处提出了一个身体安全的无线通信系统。通过利用正交OAM波模式和相之间的随机跳跃，提出了一种可信赖的对称密钥加密的关键分布机制。基于keccak-f [400]基于伪和数字生成器提供了随机性，可随机oam-wave模式的相位分布，以提供额外的安全性。我们评估在各种物理层威胁模型下使用THZ通信系统中使用OAM调制的安全漏洞，并分析这些威胁模型在不同条件下不同攻击者复杂性水平的有效性。
This paper presents a physically-secure wireless communication system utilizing orbital angular momentum (OAM) waves at 0.31THz. A trustworthy key distribution mechanism for symmetric key cryptography is proposed by exploiting random hopping among the orthogonal OAM-wave modes and phases. Keccak-f[400] based pseudorandom number generator provides randomness to phase distribution of OAM-wave modes for additional security. We assess the security vulnerabilities of using OAM modulation in a THz communication system under various physical-layer threat models as well as analyze the effectiveness of these threat models for varying attacker complexity levels under different conditions.
