Mobile Secure Network Device with Local Authentication Cache
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile server racks lack enhanced security due to their portable nature, making them vulnerable to break-ins, while existing data center security measures are ineffective in remote or unsecured locations.
Innovation Solution
A physically and electronically protected mobile security system that includes a housing for computing apparatus with access control mechanisms, a security module for authentication and data protection, a wireless router for network access, and sensors for self-mobility, along with a kill switch and motion-activated camera for breach detection and tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile server racks are made portable for remote deployment, then adaptability to different locations is improved, but security against break-ins deteriorates
Solution Approach 1:
The system divides security functions into multiple independent modules: access control mechanism, security module with local cache, motion-activated cameras, and sensors. Each module operates semi-autonomously, with the local cache enabling security decisions without continuous remote connectivity, thus maintaining security in portable remote deployments
Solution Approach 2:
A local cache is introduced as an intermediary between the remote network and the mobile server rack. This cache stores authentication credentials and security data locally, allowing the rack to verify access and maintain security protocols even when disconnected from the remote network, resolving the contradiction between portability and security
2Reliability
If access control mechanisms are added to mobile racks, then security is improved, but device complexity increases
Solution Approach 1:
Multiple security functions are merged into integrated components: the access control mechanism communicates with the security module, which coordinates with motion-activated cameras and sensors. The local cache consolidates authentication data, reducing the need for multiple separate systems and managing complexity through functional integration
Solution Approach 2:
The security module serves multiple functions: it manages authentication credentials in the local cache, controls access via the access control mechanism, coordinates camera activation, and processes sensor data. This multi-functionality reduces the number of separate components needed, managing system complexity while maintaining comprehensive security
