This invention proposes a dual reconfigurable smart surface (RIS)-assisted "one-time pad" secure wireless communication method to address the problems of low physical layer key generation rate and insufficient key rate to meet the requirements of one-time pad data transmission in wireless communication. This method constructs a controllable-random channel environment by deploying two N-unit RISs. It utilizes a multi-agent reinforcement learning (MARL) algorithm to jointly optimize the RIS phase shift and the number of key negotiation rounds, achieving a dynamic balance between data transmission rate and key generation rate. Based on this, it achieves absolutely secure communication for one-time pad data transmission. First, the legitimate communicating parties (Alice and Bob) construct a multipath random wireless channel by controlling the dual RISs based on channel reciprocity in time-division duplex (TDD) mode. Second, the MARL algorithm (including a pre-training mechanism) is used to control and optimize the phase shift of the dual RISs and determine the optimal number of key negotiation rounds for one-time pad. Finally, the physical layer key is generated through channel probing, channel estimation, quantization negotiation, and privacy amplification. Before data transmission, the generated key is used to XOR the transmitted data, achieving lightweight encryption of the transmitted data. This method significantly improves the physical layer key generation rate, provides a feasible solution for realizing "one-time key" data transmission, and is applicable to various wireless security communication scenarios such as the Internet of Things, the Internet of Vehicles, and satellite communication. It can take into account both the complexity of edge device deployment and real-time requirements.
