Cross-Platform Credential Sharing via Encrypted Token Relay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems struggle to share unclonable credentials securely between devices operating on different platforms, preventing users from granting access to secured entities like vehicles or buildings to guests without direct copying or cloning the credentials.
Innovation Solution
A credential manager generates a token and metadata for the recipient device, which is encrypted and shared through a relay server, allowing devices on different platforms to access secured entities using a password-based retrieval process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If unclonable credentials are used for secure access, then security is improved, but credential sharing between different platforms becomes impossible
Solution Approach 1:
The patent introduces a credential manager as an intermediary system that facilitates credential sharing between devices on different platforms. The credential manager receives a credential from a first device, stores it securely, and provides it to a second device without requiring direct copying or cloning. This mediator approach enables cross-platform sharing while preserving the unclonable nature of the credential.
Solution Approach 2:
The patent extracts the credential data from the original device and stores it in a separate credential manager system. By taking the credential out of the first device and placing it in the credential manager, the system enables the credential to be accessed by multiple devices without copying it from the original source, thus maintaining security while enabling sharing.
2Ease of operation
If direct credential copying is used for sharing, then ease of operation is improved, but security is compromised
Solution Approach 1:
The patent creates a reference or pointer to the credential rather than copying the actual credential data. The credential manager stores the unclonable credential and provides access to multiple devices through controlled retrieval. This approach simplifies sharing operations while maintaining security by preventing direct duplication of the credential itself.
3Reliability
If platform-specific credential formats are used, then device compatibility is improved, but cross-platform sharing becomes difficult
Solution Approach 1:
The credential manager is designed as a universal system that can handle credentials from multiple different platforms and devices. It receives credentials in various formats from different device types (smartphones, tablets, computers) and provides them back in appropriate formats, enabling cross-platform sharing while maintaining compatibility with each platform's requirements.
Data Source
AI summary
The present application relates to devices and components including apparatus, systems, and methods to share a credential for accessing a secured entity between an origination device and a recipient device. In some embodiments, the sharing may be cross platform where the recipient device executes a different platform than the origination device.
