D2D Device Registration via Mobile Terminal Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for registering and validating devices capable of device-to-device communication (D2D) with a server are prone to user errors and equipment interference, leading to inconvenient pairing processes and potential unauthorized connections.
Innovation Solution
A method and apparatus that utilize a mobile terminal to transmit and receive digital signature information and server public encryption information via D2D communication, enabling secure registration of D2D communication devices in a server by encrypting device information with the server's public encryption key.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If devices transmit validation information directly to the server via additional equipment, then the server can authenticate devices, but the pairing process may fail due to user faults or equipment interference
Solution Approach 1:
The patent introduces a mobile terminal as an intermediary device that mediates between the D2D communication device and the server. The mobile terminal receives digital signature information from the D2D device, transmits it to the server for authentication, and relays the encryption information back to the D2D device. This intermediary approach eliminates direct pairing requirements between the D2D device and server, thereby preventing pairing failures while maintaining authentication reliability.
2Reliability
If users directly input device information and digital signature information, then the server can register devices, but this causes user inconvenience
Solution Approach 1:
The patent implements self-service by enabling the D2D communication device to automatically generate and transmit its digital signature information to the mobile terminal without requiring user input. The device autonomously completes the information preparation and transmission processes, eliminating the need for users to manually input device information or digital signatures, thereby improving ease of operation while maintaining registration reliability.
3Reliability
If devices pair with additional equipment for validation, then server services can be accessed, but unauthorized devices may engage in pairing
Solution Approach 1:
The patent applies preliminary action by requiring the server to authenticate the digital signature information before providing any services or encryption information. The server validates the device's digital signature in advance, and only after successful authentication does it issue encryption information to the mobile terminal. This preliminary verification prevents unauthorized devices from obtaining service access or encryption keys, thereby eliminating the security vulnerability while maintaining proper service control.

AI summary
A method and an apparatus for validating device-to-device (D2D) communication devices in a server via a mobile terminal are provided. A 1st device-to-device (D2D) communication device includes a communication unit for communicating with a mobile terminal via D2D communication, and a controller. The controller is configured to control the communication unit to transmit digital signature information of the 1st D2D communication device to the mobile terminal, receive, when the digital signature information is successfully authenticated in a server, server public encryption information, from the mobile terminal, and transmit device information of the 1st D2D communication device, which is encrypted using the server public encryption information, to the server, and register the 1st D2D communication device in the server. The method and apparatus reduce user input for registering D2D communication devices in a server, increases user convenience, and decrease authentication time.
