Host Device Operation Data Security via Management Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computing devices face challenges in providing computer-implemented services due to inability to access data, as they require secure operation data for startup and operation, which is often restricted and not easily modifiable without authentication keys.
Innovation Solution
A system and method for managing host devices using secure storage devices with permanent authentication data, where a management controller and secured device management system facilitate secure access and updates to operation data, ensuring only authorized access through temporary and permanent authentication keys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If operation data is stored securely with permanent authentication keys, then security and authorized access are improved, but the ability to update and modify operation data is worsened
Solution Approach 1:
The system performs preliminary actions by establishing secure authentication mechanisms and authorized communication channels before any data update operations. The management controller pre-establishes trust relationships with the secured device management system, allowing future updates to proceed securely without compromising security protocols.
Solution Approach 2:
The management controller serves as an intermediary between the host device and the secured device management system. It facilitates secure communication and coordinate authentication processes, enabling data updates while maintaining security through its mediating role in the authentication and update workflow.
2Reliability
If permanent authentication data is stored in secure storage devices, then access control and security are improved, but device provisioning and reuse flexibility are worsened
Solution Approach 1:
The system implements dynamic authentication data management where temporary authentication keys are generated and distributed as needed for specific update operations. This dynamic approach allows the same secure storage device to be provisioned to multiple host devices over time, providing both strong access control and provisioning flexibility through time-bound, purpose-specific authentication.
Solution Approach 2:
The system changes authentication parameters by using different authentication keys for different purposes and time periods. Permanent authentication data remains securely stored while temporary keys are generated for specific operations, allowing the system to maintain strong access control while adapting to different provisioning scenarios and device lifecycles.
3Reliability
If authentication keys are protected and restricted, then security is improved, but the ability to modify operation data for service updates is worsened
Solution Approach 1:
The system performs preliminary authentication and establishes secure communication channels before any data modification operations. By pre-verifying the identity and authority of update sources through the management controller, the system enables rapid service updates without compromising security, as the authentication framework is already in place.
Solution Approach 2:
The system implements feedback mechanisms where the management controller continuously verifies authentication status and coordinates with the secured device management system during update operations. This feedback loop ensures security protocols are maintained while enabling efficient service updates through automated authentication and authorization checks.
Data Source
AI summary
Methods and systems for managing the operation of host devices is disclosed. A host device may include a computing device that operates in accordance with operation data. The operation data may include, for example, startup data such as code for a management entity (e.g., a basic input output system), settings (e.g., hardware and/or software) for the startup management entity, setting for general operation after booting to an operating system, copies of code (e.g., computer instructions executable with a processor) for applications to be executed by the host device, etc. If the operation data is modified, operation of the host device may be similarly modified.
