Proxy Authentication Router Service for Port Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Proxy servers face limitations in supporting multiple authentication services due to the need for unique IP address/port combinations, which can lead to port shortages and increased complexity in maintenance as the number of services grows.
Innovation Solution
Implementing an authentication router service on a single secure port that redirects and routes authentication requests to appropriate authentication services, allowing multiple proxy services to use the same or different authentication services without requiring unique IP address/port combinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a unique IP address/port combination is assigned to each authentication service, then authentication for each proxy service can be handled securely, but the number of available ports is limited and the system becomes complex to maintain
Solution Approach 1:
A single secure port is made universal to handle multiple authentication services. The port can dynamically route authentication requests to different authentication services based on the proxy service being accessed, eliminating the need for dedicated ports for each authentication service while maintaining security and authentication functionality for multiple proxy services
Solution Approach 2:
An intermediary mechanism is introduced to manage authentication requests on the single secure port. This intermediary routes requests to the appropriate authentication service based on the proxy service being accessed, allowing the system to maintain unique authentication paths for each service while using a shared port infrastructure
2Adaptability or versatility
If multiple unique IP address/port combinations are created to support growing authentication services, then each service can be authenticated independently, but the proxy server cannot support growth due to finite port availability
Solution Approach 1:
The single secure port is designed to be universal and multi-functional, capable of handling authentication for any number of proxy services. By making the port adaptable to different authentication services through routing mechanisms, the system can support service growth without being constrained by the finite number of physical ports available on the proxy server
3Device complexity
If a single secure port is used for multiple authentication services, then port availability is maximized and maintenance is simplified, but routing requests to the correct authentication service becomes complex
Solution Approach 1:
Authentication requests are pre-marked or pre-configured with information about which proxy service they belong to. This preliminary action allows the single secure port to quickly identify and route requests to the correct authentication service without complex real-time decision-making, simplifying the routing process while maintaining accuracy
Data Source
AI summary
Techniques are provided for proxy authentication. A proxy includes a first port, a second port, and a secure port; each port processing a different service. Requests received on the first and second ports which require authentication are redirected to the secure port. The secure port processes an authentication router service. The authentication router service forwards requests for authentication to selective authentication services. The authentication services authenticate the requests over the secure port.
