Controller-Specific Protection for Secure Device Data Transfers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transfer methods face inefficiencies and security risks, particularly in relocating processing operations, due to the inefficient use of namespace identifiers and the lack of protection for data during migration, which can lead to unauthorized access and data exposure.
Innovation Solution
The use of concatenated namespace identifiers and protection schemes, including encryption, to ensure secure and efficient data transfer by distinguishing between different controllers and users, and applying appropriate protection schemes based on their roles and privileges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional namespace identifiers are used for data transfer, then device relocation can be performed, but data security is compromised and unauthorized access may occur
Solution Approach 1:
The namespace identifier is segmented into multiple distinct components: a first portion identifying the namespace and a second portion identifying the controller. This segmentation allows the system to maintain security by requiring both components for valid access while keeping the overall structure manageable and organized.
Solution Approach 2:
The controller identifier is nested within the namespace identifier structure, forming a concatenated identifier where the second portion contains identification information about the controller. This nesting enables the namespace identifier to carry multiple layers of information (namespace + controller) without requiring separate identifier structures.
2Reliability
If controller-specific information is added to namespace identifiers, then data protection during transfer is improved, but the complexity of identifier management increases
Solution Approach 1:
The concatenated namespace identifier serves multiple functions simultaneously: it identifies the target namespace, identifies the source controller, and provides the basis for privilege determination. This multi-functionality eliminates the need for separate identifier structures for different purposes, simplifying overall management despite the increased information content.
Solution Approach 2:
The system automatically determines controller privileges and applies appropriate protection schemes based on the controller identifier embedded in the namespace identifier, without requiring manual configuration or intervention. The controller itself provides the information needed for its own authentication and privilege assessment.
3Object-affected harmful factors
If encryption and protection schemes are applied to data during transfer, then security risks are minimized, but processing overhead and transfer time increase
Solution Approach 1:
The system dynamically changes the protection parameter (encryption level) based on the determined privilege level of the controller. High-privilege controllers receive higher levels of protection, while lower-privilege controllers receive appropriate but less intensive protection, optimizing the balance between security and processing efficiency.
Solution Approach 2:
The system applies protection schemes selectively based on controller privileges rather than uniformly to all data transfers. This partial action approach ensures that full encryption and protection overhead are applied only when necessary for high-security transfers, reducing overall processing time for less critical operations.
4Reliability
If concatenated namespace identifiers are used to distinguish controllers, then unauthorized access is prevented, but the complexity of namespace identification increases
Solution Approach 1:
The namespace identifier is segmented into multiple distinct components: a first portion identifying the namespace and a second portion identifying the controller. This segmentation allows the system to maintain security by requiring both components for valid access while keeping the overall structure manageable and organized.
Solution Approach 2:
The controller identifier acts as an intermediary element within the namespace identifier structure, mediating between the namespace identification function and the controller authentication function. This intermediary role allows the system to maintain a unified identifier structure that serves multiple security purposes without requiring separate authentication mechanisms.
Data Source
AI summary
An apparatus may include a device including a first controller, and a second controller, wherein the device may be configured to receive, using the first controller, data, apply, to the data, a first protection scheme, and send, from the device, using the second controller, the data having a second protection scheme. The first protection scheme and the second protection scheme may be the same. The second controller may be configured to apply, to the data, the second protection scheme. The first protection scheme may include a first salt, and the second protection scheme may include a second salt. The first salt may be determined by the device, and the second salt may be determined by a user. The method may further include applying, at the device, to controller state information for the first controller, a third protection scheme to generate controller state information having the third protection scheme.
