Adapting Communication Station Security via Identification Module Events
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems do not effectively adapt security settings in response to hardware changes in mobile terminals, leading to potential exposure of sensitive credentials and a lack of enforced security policies, as SIM cards are not aware of such changes and implement independent security mechanisms.
Innovation Solution
A communication station with a processor that applies and updates security mechanisms based on stored settings in response to hardware configuration changes, using an identification module with an event handler and security registry to manage access and authentication, ensuring seamless and secure access to sensitive information and functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If SIM cards implement independent security mechanisms without awareness of hardware changes, then security policies are not enforced, but system complexity is reduced
Solution Approach 1:
The patent merges the security mechanism into the identification module (SIM card) itself, combining hardware change detection capabilities with security policy enforcement. The security mechanism is no longer independent but integrated within the identification module, allowing it to autonomously respond to hardware changes while maintaining security policies.
Solution Approach 2:
The invention implements a feedback mechanism where the identification module continuously monitors hardware configuration changes and automatically adjusts security settings in response. When hardware changes are detected, the security mechanism receives feedback about the change state and modifies access controls accordingly, creating a closed-loop security system.
2Reliability
If security settings are statically configured, then implementation is simple, but security cannot adapt to hardware changes leading to credential exposure
Solution Approach 1:
The patent transforms static security settings into dynamic ones that automatically adapt to hardware configuration changes. The security mechanism transitions from a fixed configuration to a flexible system that responds in real-time to hardware events, adjusting access controls based on the current hardware state without requiring manual reconfiguration.
Solution Approach 2:
The identification module performs self-service by autonomously detecting hardware changes and adjusting its own security settings without external intervention. The system monitors its own hardware environment and automatically modifies security parameters, enabling the security mechanism to serve and protect itself.
3Reliability
If access control is strictly enforced based on hardware configuration, then security is improved, but ease of operation is reduced
Solution Approach 1:
The patent dynamically changes security parameters based on hardware configuration states. Instead of maintaining a single fixed access control level, the system adjusts security parameters (such as authentication requirements or access permissions) according to the detected hardware configuration, allowing flexible adaptation between security and usability based on the operational context.

AI summary
A method for adapting the security settings of a communication station (12) depending on a security relevant event is disclosed, wherein the communication station (12) comprises a mobile terminal (16) with an identification module (18). In a first step, the security relevant event occurring in said communication station and/or said mobile terminal (16) is identified in an event handler (26, 261, 262, 27) and stored in an event registry (28). In a second step, a security registry (30) in the identification module (18) is updated according to the identified event, In a third step, the security level of the communication station (12) and/or the mobile terminal (16) €s adapted according to the security registry (30) of the identification module (18). The invention also relates to a communication station (12) and to an identification module (18).
