Cross-Device Authentication for Seamless Secure Remote Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The tedious and disruptive identity authentication process required for each session instantiation on computing devices, particularly in cloud-based services, negatively impacts user experience.
Innovation Solution
A method and system for secure remote hardware access through cross-device authentication, involving provisioning a client device with an authentication token, comparing it with pre-authorized tokens, and unlocking access control locks on remotely located hardware devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If identity authentication is performed for every session instantiation on each computing device, then security is maintained, but user experience deteriorates due to tedious repeated authentication
Solution Approach 1:
The patent implements preliminary action by establishing a persistent authenticated state between the user and cloud services server that survives across different computing devices. The server maintains authentication state in a database, allowing the user to access services on multiple devices without re-authenticating, thus improving ease of operation while maintaining security through pre-established trust relationships
2Ease of operation
If authentication tokens are stored and compared across devices, then convenient cross-device access is enabled, but system complexity increases
Solution Approach 1:
The patent applies the intermediary principle by introducing a cloud services server as a central mediator that handles authentication token management across devices. The server receives authentication tokens from client devices, compares them against stored pre-authorized tokens in a database, and manages the authentication state, thereby simplifying the complexity of cross-device authentication through a centralized coordination point
