Dynamic VLAN Assignment for Secure Headless Device Network Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for network access management in network-enabled devices, particularly for headless computing devices (HCDs), fail to provide secure and uninterrupted access when multiple users or devices compete for the same VLAN, leading to potential data security risks and challenges in associating devices without traditional authentication mechanisms.
Innovation Solution
A system and method that utilizes dynamic VLAN assignment and cloud-based authentication to automatically create user profiles bound to geographic locations, assign VLANs based on existing profiles, and associate devices securely, even for HCDs, using MAC addresses or other unique identifiers, while enabling device roaming across networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dynamic VLAN assignment is implemented to provide secure network access for multiple users, then network security is improved, but system complexity increases
Solution Approach 1:
The patent introduces a cloud-based authentication system as an intermediary between users and the network infrastructure. This centralised system automatically creates user profiles, assigns VLANs, and manages device associations, eliminating the need for complex local authentication mechanisms at each network device while maintaining high security standards.
Solution Approach 2:
The system enables automatic self-service functionality where the authentication server autonomously creates user profiles, assigns appropriate VLANs based on geographic location and user credentials, and associates devices without requiring manual configuration. This automation reduces system complexity while enhancing security through consistent policy enforcement.
2Ease of operation
If automatic user profile creation and VLAN assignment is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The authentication system automatically creates user profiles when users provide credentials, assigns appropriate VLANs based on geographic location and user type, and associates devices without manual intervention. This self-service automation significantly improves ease of operation while the centralised architecture manages the inherent complexity remotely.
Solution Approach 2:
The patent replaces manual mechanical configuration processes with automated electronic authentication and profile management systems. The cloud-based server handles all complex operations electronically, substituting manual setup and configuration with automated digital processes that simplify user interaction.
3Adaptability or versatility
If cloud-based authentication is used to support headless devices without traditional authentication methods, then adaptability is improved, but system complexity increases
Solution Approach 1:
The authentication system is designed to handle multiple device types universally, including traditional devices with user interfaces and headless devices without traditional authentication mechanisms. The system adapts its authentication method based on device capabilities, using MAC addresses, embedded identifiers, or other unique device characteristics for headless devices while maintaining the same security framework.
4Reliability
If VLAN assignment is based on geographic location and existing profiles, then network security is improved, but loss of time occurs during device association
Solution Approach 1:
The system performs preliminary actions by pre-creating user profiles with assigned VLANs before devices need to connect. When users register their devices, the authentication server has already prepared the appropriate VLAN assignments based on geographic location and user credentials, eliminating the need for time-consuming real-time VLAN creation and configuration during device association.
Data Source
AI summary
A system and corresponding computer-implemented method provide secure network access to network-enabled devices. The computer-implemented method creates a user profile, automatically. The user profile is bound to a physical geographic location. The user profile provides access rights to a network. The computer-implemented method assigns, automatically, at least one VLAN to the user profile created. The assigning is based on whether there is an existing user profile bound to the physical geographic location. The computer-implemented method associates, automatically, the user profile created with a network-enabled device. The assigning and associating provide the network-enabled device with secure network access to the network.
