Secure Module Local Profile Management Activation Agent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing secure modules in electronic devices lack the ability to securely manage subscriber profiles locally, and there is a need to ensure the coexistence of local and remote management modes while maintaining security and operator control over configuration actions.
Innovation Solution
An electronic device with a secure module that includes a local manager and an activation agent to detect and authorize or prohibit local configuration requests, using secure radiofrequency transport protocols and interface notifications to manage local profile activation, deactivation, and deletion requests, ensuring secure local management and cooperation with remote servers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If local profile configuration requests are allowed to be processed by the secure module, then user autonomy and local management capability are improved, but security risks and potential unauthorized modifications increase
Solution Approach 1:
The activation agent serves as an intermediary component between the local manager and the secure module. It intercepts local profile configuration requests, verifies their authenticity and authorization status, and only permits processing of validated requests. This mediator ensures that local management operations are securely controlled without compromising user autonomy.
2Adaptability or versatility
If the secure module supports both local and remote management modes, then system versatility and adaptability are improved, but system complexity and management overhead increase
Solution Approach 1:
The management system is segmented into distinct functional components: a local manager for local requests, a remote manager for remote requests, and an activation agent that coordinates between them. Each component has a specific responsibility, and the activation agent maintains state information about which management mode is currently active. This segmentation allows both local and remote modes to coexist without creating excessive system complexity.
3Reliability
If the activation agent detects and authorizes local configuration requests, then security control is improved, but processing time and operational delays increase
Solution Approach 1:
The activation agent performs preliminary actions by pre-establishing authorization states and detecting the operational mode in advance of actual profile configuration requests. By determining whether local management is authorized before requests arrive, the system avoids time-consuming verification delays during actual configuration operations, while still maintaining security control.
