Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current networks lack end-to-end authentication and authorization measures for cardless/USIM-less wireless end devices connecting to application service layer networks, posing security risks due to the lack of validation for these devices in the radio access network, core network, and application service layer network.
Innovation Solution
Implementing an intelligent network device with AI/ML logic to generate and update identity profiles for SIM-less end devices, perform authentication and authorization using composite identifiers, and provide end-to-end validation through intelligent secure access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If SIM-less end devices connect to networks without traditional authentication mechanisms, then device connectivity and accessibility are improved, but network security and authorization reliability deteriorate
Solution Approach 1:
The patent introduces an intermediary authentication system that mediates between SIM-less end devices and the core network. This intermediary validates device identities and establishes secure connections without requiring traditional SIM cards, thus maintaining ease of connectivity while ensuring network security through intermediate verification layers.
Solution Approach 2:
The system performs preliminary authentication and authorization actions before allowing SIM-less devices to access the network. By pre-validating device identities and establishing security credentials in advance, the system enables easy connectivity for authorized devices while preventing unauthorized access, thus resolving the security concern.
2Reliability
If traditional authentication mechanisms are used for all devices, then network security is improved, but device accessibility and flexibility deteriorate
Solution Approach 1:
The patent applies different authentication qualities to different device types. SIM-based devices continue to use traditional authentication mechanisms, while SIM-less devices use alternative authentication methods. This localized approach maintains high authentication validity for traditional devices while improving accessibility for modern SIM-less devices.
Solution Approach 2:
The authentication system is designed to handle multiple device types universally. It can authenticate both traditional SIM-based devices and modern SIM-less devices through different but compatible mechanisms, thus maintaining authentication reliability across all device types while improving overall system versatility and accessibility.
3Object-affected harmful factors
If end-to-end authentication is implemented for SIM-less devices, then security risks are reduced, but system complexity increases
Solution Approach 1:
The patent segments the authentication process into distinct modular components: device identification, credential validation, authorization, and secure connection establishment. This segmentation allows each security function to be implemented independently and efficiently, reducing overall system complexity while maintaining comprehensive end-to-end authentication for SIM-less devices.
