The paper presents Grain-128PLE, a physical layer encryption scheme for IoT networks. It performs encryption and decryption at the physical layer, providing a generic solution for data confidentiality. The design is based on the Grain-128AEAD v2 stream cipher. The paper discusses the importance of physical layer security (PLS) and contrasts it with traditional cryptographic schemes. It highlights the resource efficiency of PLS-based techniques, making them suitable for IoT networks with inherent resource constraints. The paper also mentions two main approaches at the physical layer: channel coding-based secrecy and signal modulation-based encryption.
