Portable Device Authentication for Failed Hardware Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In storage system environments, detecting and repairing failed hardware components is challenging due to the need for secure and timely access, especially in dual server configurations where one server must take over the operations of another, and existing methods lack efficient mechanisms for accessing and replacing malfunctioning components without disrupting system operations.
Innovation Solution
A portable handheld device receives authentication codes and location information for failed hardware components from a central repository, establishing a secure connection to access and repair or replace the components within a designated time window, ensuring minimal disruption to the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If secure access mechanisms are implemented for failed hardware components, then system security is improved, but access time and repair complexity increase
Solution Approach 1:
The system performs preliminary actions by pre-generating authentication codes and time windows for potential hardware failures before they occur. When a component fails, the pre-prepared access credentials enable immediate secure access without time-consuming authentication processes, thus maintaining security while minimizing access time.
Solution Approach 2:
The patent introduces an intermediary mechanism (authentication code system) that mediates between security requirements and rapid access needs. The portable handheld device acts as an intermediary tool that stores and presents pre-authenticated credentials, allowing service personnel to access secured hardware components quickly while maintaining the security framework.
2Reliability
If dual server configuration is used for failover, then system reliability is improved, but system complexity increases
Solution Approach 1:
The system implements self-service capabilities where the dual server configuration automatically detects failures and performs failover without manual intervention. The authentication system also operates autonomously, automatically providing access credentials to authorized personnel without requiring complex manual authentication procedures, thus reducing operational complexity while maintaining high availability.
3Reliability
If hardware components are secured with authentication mechanisms, then unauthorized access is prevented, but ease of repair decreases
Solution Approach 1:
The patent employs disposable or short-lifetime authentication codes that are pre-loaded onto portable handheld devices. These codes are designed for single-use or limited-use scenarios, providing strong security for each access event while requiring no complex recovery mechanisms. The simplicity of the code-based system greatly ease of repair compared to traditional authentication systems.
Data Source
AI summary
A portable handheld device receives from a central repository, information on a failed hardware component of a computational device, wherein the information includes an authentication code to permit access to the failed hardware component and a time window in which the failed hardware component is permitted to be accessed. The portable handheld device uses the authentication code to access the failed hardware component for repair or replacement during the time window.
