SSD Secure Element Coupling Structure for Data Destruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Solid state drive (SSD) devices face security issues such as data leakage during theft or loss, as existing solutions lack a fundamental mechanism to prevent external intrusion and ensure secure data destruction.
Innovation Solution
The integration of a coupling structure within the SSD device that securely mounts a secure element to a substrate, ensuring destruction or separation of the secure element when the case is removed, maintaining connection integrity while preventing access to secure data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the case is made removable for maintenance or upgrade purposes, then ease of operation is improved, but security is worsened as elements inside may be seen and hacked
Solution Approach 1:
The secure element is segmented from the substrate through the coupling structure that connects it to the case. When the case is removed, the secure element is automatically separated from the substrate, preventing data access while allowing case removal for maintenance or upgrade purposes.
Solution Approach 2:
The coupling structure is designed to prevent data leakage before it can occur. By maintaining the secure element's connection to the case rather than the substrate, the system proactively prevents unauthorized access to secure data when the case is removed, eliminating the need for post-removal security measures.
2Reliability
If the secure element is firmly mounted to the substrate, then reliability is improved, but security is worsened as the secure element cannot be destroyed or separated when the case is removed
Solution Approach 1:
The secure element is segmented into a separate mounting system connected to the case rather than being firmly mounted to the substrate. This segmentation allows the secure element to be reliably connected during normal operation while enabling automatic separation and destruction of data access when the case is removed.
Solution Approach 2:
Instead of mounting the secure element to the substrate and preventing access through substrate removal, the invention inverts the approach by mounting the secure element to the case. This allows case removal to trigger secure element separation and data destruction, reversing the traditional mounting paradigm to achieve both reliability and security.
3Object-affected harmful factors
If a coupling structure is introduced to connect the secure element to the case, then security is improved, but device complexity is worsened
Solution Approach 1:
The coupling structure merges multiple functions into a single component: it mechanically connects the secure element to the case, maintains alignment during assembly, and enables automatic separation when the case is removed. This integration reduces the need for additional security mechanisms while achieving comprehensive data protection.
Solution Approach 2:
The coupling structure serves multiple purposes: structural support for the secure element, alignment guide during assembly, and security mechanism for data protection. By making the coupling structure multi-functional, the invention reduces overall device complexity while improving security capabilities.
Data Source
AI summary
A storage device includes a substrate, at least one secure element, a case and a coupling structure. The secure element is mounted on the substrate. The case surrounds the substrate and the secure element. The coupling structure integrally couples the secure element and the case. When at least a part of the case is removed, the secure element is destroyed while a connection remains between the secure element and the case by the coupling structure, and access to secure data stored in the secure element is prevented.
