Three-Way Authentication for Remote Cloud 3D Printing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D printing technologies require users to be physically present near the printer, incur high wireless network costs due to large data processing, and lack effective three-way authentication methods for smartphone-3D printer-cloud server configurations, limiting the scale and accessibility of 3D printing services.
Innovation Solution
A three-way authentication method in a cloud environment that enables mutual authentication between a control device, a service device, and a function server through specific interfaces (IF-1, IF-2, and IF-3), allowing a user terminal to control a 3D printer via a mobile device, with authentication tokens facilitating secure interoperation between devices and servers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If 3D printing is performed using current technology with user presence required, then printing tasks can be monitored, but user mobility is restricted and time consumption increases
Solution Approach 1:
The patent introduces a cloud server as an intermediary between the user's mobile terminal and the 3D printer. The cloud server receives printing requests from the mobile terminal, manages the printing process, and sends notifications when printing is complete. This allows users to initiate and monitor 3D printing tasks remotely without being physically present at the printer, resolving the contradiction between user mobility and printing monitoring.
2Productivity
If large-capacity 3D content is processed via smartphone, then printing control is achieved, but communication expenses increase and functionality is limited
Solution Approach 1:
The patent segments the 3D printing system into three distinct components with divided responsibilities: the mobile terminal handles user interaction and authentication, the cloud server manages large-capacity content processing and printing task coordination, and the 3D printer executes the actual printing. This segmentation allows large files to be processed via the cloud server rather than transmitted through the mobile terminal, reducing communication expenses and leveraging cloud computing power.
3Reliability
If three-way authentication is implemented for smartphone-3D printer-cloud server, then security is improved, but system complexity increases
Solution Approach 1:
The cloud server acts as an authentication intermediary that issues authentication tokens to both the mobile terminal and the 3D printer. The mobile terminal and printer perform mutual authentication through the cloud server using these tokens, establishing secure connections without requiring direct complex authentication protocols between them. This intermediary approach simplifies the overall authentication architecture while maintaining high security standards.

AI summary
Disclosed herein are a three-way authentication apparatus and method in a cloud environment. The three-way authentication method in a cloud environment includes performing, by a control device and a service device, mutual authentication through an IF-1 interface, performing, by the control device and a function server, mutual authentication through an IF-2 interface, requesting, by the control device, the function server to issue an authentication token for authentication between the service device and the function server, and delivering an authentication token issued by the function server to the service device, and performing, by the service device, mutual authentication with the function server using the delivered authentication token through an IF-3 interface.
