Dynamic Access Control for Information Storage During Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data processing systems face challenges in securely managing access to information storage during operations, particularly in ensuring that sensitive data is protected from external access while allowing secure data processing operations to proceed insularly.
Innovation Solution
A method and device configuration that allows a processing unit to perform data processing operations while restricting access to an information storage, switching between accessible and inaccessible modes based on operation codes, ensuring that the storage is only accessible by the processing unit during operations, thereby preventing external read/write access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the information storage is made accessible by the first unit during data processing operations, then the ease of operation is improved, but the security and reliability of sensitive data deteriorates
Solution Approach 1:
The patent implements dynamic access control by switching the information storage between accessible and inaccessible states based on the operational phase. During data processing operations, the storage transitions to an inaccessible state for the first unit, while during non-operational phases, access is restored. This dynamic state change resolves the contradiction by providing security when needed and operational ease when safe.
Solution Approach 2:
The access control operates periodically, alternating between accessible and inaccessible modes based on the execution cycle of data processing operations. The storage is made inaccessible during operation execution and accessible during idle periods, creating a periodic pattern that balances security requirements with operational needs.
2Reliability
If access restrictions are imposed on the information storage during processing operations, then the security of data is improved, but the productivity of the system deteriorates
Solution Approach 1:
The patent segments the access control into distinct phases: before operation execution (accessible), during operation execution (inaccessible), and after operation completion (accessible again). This segmentation allows the system to maintain high productivity during accessible phases while ensuring data protection during critical processing phases, resolving the contradiction between security and productivity.
Solution Approach 2:
The access control mechanism ensures continuous useful action by minimizing the duration of inaccessible states to only when absolutely necessary (during operation execution). The system quickly transitions between states, ensuring that productivity is maintained for the majority of the operational cycle while security is enforced during critical moments.
3Reliability
If the information storage is protected from external access during operations, then the integrity of data processing is improved, but the complexity of the access control mechanism increases
Solution Approach 1:
The access control mechanism operates autonomously based on the operational state of the processing unit. The controller automatically switches the information storage between accessible and inaccessible states without requiring complex external control logic or manual intervention. This self-service approach maintains data integrity while minimizing the complexity of the access control structure.

AI summary
Embodiments related to a processing unit and a first information storage are described and depicted. First information is provided from a first unit into a first information storage for performing a first operation of the processing unit. During the first operation of the processing unit second information is transferred between the processing unit and the first information storage. The first information storage comprises during the first operation of the processing unit an access protection for the first unit.
