Description

technical field [0001] The invention belongs to the technical field of communication network security, and in particular relates to a unified lightweight traceable secure data transmission method for D2D auxiliary communication. Background technique [0002] Currently, with the rapid growth of mobile devices and traffic, fifth-generation (5G) networks are designed to provide users with higher speeds, lower latency, and greater wireless capacity. As a direct communication technique, device-to-device (D2D) communication transfers data transmission to the device, leaving only control signals to the base station. Compared with the traditional way of unified transmission of signals and data through base stations in fourth-generation (4G) networks, the separation of data transmission and control signaling enables traffic offloading of base stations, thereby reserving more bandwidth for uplink and Downlink, relieves pressure on base station capacity and enables efficient data tran...

AI Technical Summary

Problems solved by technology

However, since mobile devices communicate over wireless channels, they are vulnerable to eavesdropping, forgery, dropping, etc.

In addition, considering the unreliability of mobile nodes in data transmission, the transmission is threatened by confidentiality, integrity, privacy violation, etc.

In addition, since moving relay nodes consume energy resources during transmission, relay nodes will refuse to cooperate if there is no reasonable reward

[0004] 3GPP has considered standards for building a security architecture for 5G networks and their services, however, research on D2D security is still at an early stage

[0006] Through the above analysis, the problems and defects of the existing technology are: the D2D security solution in the prior art is not suitable for the D2D auxiliary relay data transmission scenario, and cannot realize data transmission track tracking and anonymity

[0007] The difficulties in solving the above problems and defects are: 1. It is difficult to realize the mutual authentication between the source device and the destination device node; 2. It is difficult to realize privacy protection in hop-by-hop broadcast data transmission; 3. It is difficult to trace the source of data transmission trajectory
