Engineering Contradiction Analysis
1Quantity of substance
If traditional RF-based wireless communication is used for node addition, then wireless connectivity is achieved, but the RF spectrum becomes saturated and communication efficiency decreases
Solution Approach 1:
The patent transitions from RF-based wireless communication to light-based communication (LiFi), changing the dimensional space from radio frequency spectrum to optical spectrum. This allows simultaneous wireless communication without interfering with traditional RF bands, effectively adding a new communication dimension that resolves spectrum saturation while maintaining wireless connectivity for node addition
2Reliability
If manual node addition procedures are used, then security and trust verification can be performed, but the process consumes significant time and increases administrative complexity
Solution Approach 1:
The patent implements preliminary action by pre-configuring unique identifiers (LDNA) and cryptographic credentials in nodes before they join the network. When a node attempts to join, the light carrier automatically transmits these pre-configured credentials for immediate verification, eliminating the need for time-consuming manual security procedures while maintaining robust trust verification
Solution Approach 2:
The system enables self-service by allowing nodes to automatically perform their own authentication and registration with the network using light carrier communication. The unique identifiers and cryptographic protocols enable nodes to self-verify and self-register without requiring manual administrative intervention, thereby maintaining security while dramatically reducing addition time
3Reliability
If manual configuration is performed for node addition, then secure integration is achieved, but device complexity and administrative burden increase
Solution Approach 1:
The patent replaces manual mechanical configuration procedures with automated light carrier-based communication. The optical signal automatically transmits node identifiers and cryptographic credentials, substituting manual administrative actions with automated optical signaling and electronic verification, thereby maintaining secure trusted device integration while reducing administrative complexity

AI summary
Light signal-based networking, such as LiFi (light fidelity), has become more prevalent. Such networking means provide a bidirectional wireless system that transmits data via LED or infrared light. Embodiments use light-signal-based networking to easily and securely add new information handling systems to an existing network. In one or more embodiments, matching both pre-set light carrier settings and trust data help make the addition of a node to the network quick and secure. In one or more embodiments, additional security and authentication mechanisms (e.g., tunneling, multi-factor authentication, passwords, token+passwords, secure protocols (e.g., Role-Based Access Control (RBAC), Lightweight Directory Access Protocol (LDAP), etc.) may also be used to further strengthen trust for the network, for the new client node, or both. Once trusted, information about the new client may be added to a datastore to allow other nodes in the network access to a listing of trusted nodes.
