Re-configurable Data Communication Device for Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard electronic device architectures allow direct access to native resources, creating security vulnerabilities that can be exploited by cyberattacks, as they bypass operating system supervision and security mechanisms.
Innovation Solution
A safe case with a controller that manages both the control and data planes of data communication, re-configures operating parameters of a re-configurable data communication device to a trusted clean state by applying a trusted firmware image, thereby wiping out malicious codes and enhancing security and privacy protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If direct access to native resources is allowed for performance consideration, then data communication speed is improved, but security mechanisms are bypassed creating security vulnerabilities
Solution Approach 1:
The patent introduces a re-configurable data communication device as an intermediary layer between the application layer and native resources. This device provides DMA capabilities while maintaining security through configurable access control, thus resolving the contradiction by enabling fast data communication without directly bypassing security mechanisms.
Solution Approach 2:
The patent segments the data communication function into multiple layers: the re-configurable device handles high-speed DMA operations while the controller manages security policies and firmware configuration. This segmentation allows performance-critical functions to operate independently while security functions remain under supervision.
2Reliability
If re-configuration of data communication device is performed to restore trusted state, then security is improved, but device operational time is reduced due to re-configuration interruptions
Solution Approach 1:
The system performs preliminary validation of firmware images before applying them, and maintains a ready-state trusted firmware image. This allows rapid re-configuration when security events are detected, minimizing operational interruption while ensuring security integrity.
Solution Approach 2:
The re-configuration process changes the firmware image parameter of the data communication device, transitioning it from a potentially compromised state to a trusted state. This parameter change restores security without requiring complete device replacement or prolonged downtime.
