Security Module Network Authentication Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security modules for communication terminals do not effectively tie the usage of network-independent application modules to a specific telecommunications network, allowing users to access these applications without necessarily using the operator's network.
Innovation Solution
A security module with a locking and unlocking mechanism, controlled by a module that enables or disables the usability of application modules based on authenticated data from a specific telecommunications network, ensuring that network-independent applications can only be used when the user is registered and authenticated within that network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network-independent application modules are provided in the security module, then the functionality and versatility of the security module is improved, but the operator loses control over whether subscribers use these applications without using the operator's telecommunications network
Solution Approach 1:
The patent implements dynamic control of application module usability through a control module that receives authentication data from the telecommunications network and dynamically enables or disables application modules based on whether the subscriber is authenticated with the operator's network. This resolves the contradiction by making the system adaptable (principle 35) while maintaining operator control (principle 15), as the application modules can be dynamically locked or unlocked based on network authentication status.
2Ease of operation
If the security module allows access to application modules without network authentication, then the ease of operation for users is improved, but the operator cannot tie the usage of applications to the usage of their network
Solution Approach 1:
The patent implements preliminary locking of application modules before network authentication occurs. The control module receives authentication data from the telecommunications network and only after successful authentication does it enable the application modules. This preliminary locking mechanism ensures that users cannot access applications without first being authenticated with the operator's network, thereby maintaining the reliability of network usage tying while preserving ease of operation after authentication.

AI summary
For a communication terminal (10), proposed is a security module (1) configured to authenticate a telecommunications network (2). The security module (1) comprises a locking module (12), for disabling usability of an application module (11), an unlocking module (13), for re-enabling usability of the application module (11), and a control module (14) for activating the unlocking module (13), depending on received data that is assignable in an authenticated way to a specific telecommunications network (2). The control module (14) is configured to activate the locking module (12) depending on the selection and usage of the application module (11). The control module (14) is configured to activate the unlocking module (12) depending on the reception of authorization messages, that can be authenticated, or authentication data of the telecommunications network (2). By disabling and re-enabling usability of the application module (11), depending on received data that is assignable in an authenticated way to a specific telecommunications network (2), the usage of network independent applications can be tied to the usage of a specific telecommunications network.
