LAN Service Authentication via Segmented Security Tokens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for accessing services over a local area network (LAN) lack secure authentication and service discovery mechanisms, making them vulnerable to unauthorized access and insecure service announcements.
Innovation Solution
The implementation of methods and systems that establish secure communication sessions by authenticating devices, issuing security tokens, and encrypting data transmissions to ensure secure access and discovery of services over a LAN.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If device-specific authentication is used for service access, then authentication can be performed, but it does not provide application-specific security and allows unauthorized access
Solution Approach 1:
The patent segments authentication into device-level and application-level components. Device authentication establishes base access rights, while application-specific tokens provide granular permission control for individual services, resolving the contradiction between comprehensive security and operational convenience
Solution Approach 2:
The patent introduces security tokens as intermediary elements between authenticated devices and services. These tokens act as mediators that carry application-specific authorization information, enabling convenient service access while maintaining strong security through token-based validation
2Adaptability or versatility
If service discovery is performed without security measures, then service accessibility can be determined, but the procedure becomes insecure and vulnerable to unauthorized access
Solution Approach 1:
The patent performs preliminary authentication and token issuance before service discovery occurs. Devices must be authenticated and receive appropriate tokens prior to discovering or accessing services, ensuring that service discovery happens within a already-secured context rather than as a separate vulnerable step
Data Source
AI summary
Systems and methods for providing one or more secure services are disclosed. One method can comprise authenticating and/or authorizing a user device to receive a security token. A request for information can be processed using the security token to facilitate the secure provision of services to the user device.
