这封信提出了一种高效的基于极性码的物理层加密（PLE）方案，与传统的对称密钥密码系统相比，其密钥长度较短。通过使用极性码的特性，我们考虑了几种有效的技术来减少所提出的 PLE 方案的密钥长度和计算开销。此外，安全分析的结果表明，所提出的方案对于针对PLE方案的常规攻击具有较高的安全性。事实上，减少所提出的PLE方案的密钥长度和计算开销对其安全级别没有影响，这使得它适合资源有限的安全移动通信设备。
This letter presents an efficient polar code-based physical layer encryption (PLE) scheme with a short key length in comparison to the conventional symmetric key cryptosystems. By using the properties of polar codes, we consider several efficient techniques to reduce the key length and the computational overhead of the presented PLE scheme. Moreover, the results of the security analyses show that the proposed scheme has a high level of security against conventional attacks on the PLE schemes. In fact, reducing the key length and the computational overhead of the presented PLE scheme has no effect on its security level, which makes it suitable for secure mobile communication devices with limited resources.
