Gateway Daemon Authentication for Secure Network Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network protocols, such as SSH, are not suitable for daemon-based network services, particularly in ensuring authentication and encryption for secure data transmission over public networks, which can lead to unauthorized access and data integrity issues.
Innovation Solution
A method and system that establish an encrypted session with a requestor, utilize a temporary process to authenticate and authorize access, and redirect service requests to a service daemon if authorized, ensuring secure communication without altering the protocol daemon.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If SSH transport protocol is used for network services, then authentication and encryption are provided, but it cannot be used for daemon-based network services
Solution Approach 1:
A gateway device is introduced as an intermediary between the requestor and the service daemon. The gateway establishes an encrypted SSH session with the requestor, then communicates with the service daemon through internal interfaces. This mediator approach allows SSH security features to be applied to daemon-based services without requiring the daemons themselves to implement SSH protocols.
Solution Approach 2:
The system is divided into separate functional components: the gateway device that handles authentication and encryption, and the service daemon that provides the actual service. This segmentation allows each component to specialize in its function - the gateway handles security protocols while the daemon handles service logic, resolving the incompatibility between SSH requirements and daemon architecture.
2Reliability
If multiple service copies are created to handle requests, then service availability is improved, but network device resources are consumed
Solution Approach 1:
The gateway device provides a centralized service that handles authentication and request routing. Instead of each service instance independently handling authentication, the gateway serves all authentication requests centrally, reducing redundant resource consumption while maintaining service availability through the routing capability.
Solution Approach 2:
The gateway device performs multiple functions: establishing encrypted sessions, authenticating requestors, routing requests to appropriate service daemons, and managing connections. This multi-functional approach consolidates resources that would otherwise be distributed across multiple service copies, reducing overall resource consumption while maintaining availability.

AI summary
A system receives a request from a requestor for a service performed by a network device, establishes an encrypted session with the requestor, and utilizes a temporary process to determine whether the requestor is authorized for the service. If the requestor is authorized, the system redirects the service request to the service, and provides the service to the requestor.
