Mobile Device Cloud Trust via Digital Certificates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for downloading and installing applications on mobile devices to connect and control Internet-connected host systems, such as vehicles, are cumbersome and require multiple user interactions, often lacking in security and efficiency.
Innovation Solution
A system that utilizes a cloud-based service to facilitate secure connections between mobile devices and Internet-connected hosts through digital certificates, out-of-band data exchange, and local wireless connections, minimizing user interaction by pre-configuring applications and establishing trust relationships using NFC, QR codes, and biometric verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional methods are used to download and install applications on mobile devices to control Internet-connected hosts, then the application can be installed, but the process requires multiple user interactions and is cumbersome
Solution Approach 1:
The system performs preliminary actions by pre-configuring applications on the mobile device before the user needs to use them. The cloud service automatically downloads, installs, and configures the appropriate application based on the host system type, eliminating the need for users to manually perform these setup steps.
Solution Approach 2:
The system enables self-service by allowing the mobile device to automatically obtain and install the correct application through cloud-based services without requiring user intervention. The device autonomously completes the entire application deployment process including download, installation, and configuration.
2Reliability
If traditional application download methods are used, then applications can be installed, but security is compromised and phishing attacks are possible
Solution Approach 1:
The cloud-based service acts as an intermediary between the user and the application download process. Instead of users directly searching for and downloading applications from potentially malicious sources, the cloud service mediates by verifying and delivering only authenticated, secure applications from authorized sources.
Solution Approach 2:
The system applies preliminary anti-action by pre-approving and securing applications before they are made available to users. The cloud service performs security verification and authentication in advance, preventing malicious applications from reaching users in the first place.
3Reliability
If multiple steps are required to download, install, and configure applications, then proper authentication can be achieved, but the process becomes complex and error-prone
Solution Approach 1:
The system merges multiple separate steps (download, installation, configuration, authentication) into a single automated process. The cloud service combines these distinct operations into one unified workflow that executes automatically without requiring users to navigate through multiple manual steps.
4Reliability
If users manually configure applications to access host systems, then proper connectivity can be established, but user interaction and potential for errors increase
Solution Approach 1:
The system enables self-service by allowing the mobile device to automatically establish connections to host systems without user intervention. The device autonomously retrieves connection parameters, configures communication channels, and establishes authenticated sessions with the host system automatically.
Data Source
AI summary
Applications are downloaded to a device from a cloud-based service by establishing trust with between the device and a host system. The host system and the cloud-based service have a pre-existing trust relationship.
