Key generation method based on reconfigurable intelligent surface in quasi-static scene
Aiming at the problems of slow channel changes and low key generation rate in IoT quasi-static scenarios, a key generation method based on reconfigurable intelligent surface (RIS) was proposed.First, the agility characteristics of RIS was used to construct a fast-changing channel.Then, the base stat...

| description | Aiming at the problems of slow channel changes and low key generation rate in IoT quasi-static scenarios, a key generation method based on reconfigurable intelligent surface (RIS) was proposed.First, the agility characteristics of RIS was used to construct a fast-changing channel.Then, the base station and legitimate users extracted a consistent key from the channel information through channel estimation, conversion, and information negotiation.Finally, optimal time allocation for data transmission and key generation in the coherent time to achieve the maximum transmission rate of one-time pad.The simulation results show that the key generation rate of proposed method is higher than that of the existing relay-assisted method, random signal flow method and random number method, and as the number of RIS reflection units and frequency of channel estimation in the coherence time increase, the key generation rate will be further improve. |
