Boat Network Authentication Control Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication methods for connection devices on a boat network are unable to handle specific devices as authentication-free, as they perform universal authentication irrespective of the manufacturer or device class, leading to inefficiencies.
Innovation Solution
A control method and device that perform an authentication-free determination based on the manufacturer code of the connection device, exempting devices from authentication if they correspond to a specific manufacturer, and conducting authentication only if they do not match, using an address requesting message with a data field containing manufacturer codes and device information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If universal authentication is performed for all connection devices, then network security is improved, but device complexity and operational overhead increase
Solution Approach 1:
The patent applies local quality by differentiating authentication requirements based on device characteristics. Connection devices are categorized into two groups: those requiring authentication (with cryptographic keys) and those exempted (without cryptographic keys). This localized approach to authentication based on device-specific properties resolves the contradiction by maintaining security for devices that need it while simplifying the process for devices that don't require it.
2Reliability
If authentication is performed for all connection devices, then network security is improved, but operational efficiency deteriorates
Solution Approach 1:
The patent implements local quality by applying different authentication procedures to different connection devices based on their characteristics. Devices identified as requiring authentication undergo the full cryptographic verification process, while devices identified as not requiring authentication are exempted. This resolves the contradiction by maintaining security where necessary while eliminating unnecessary authentication steps that reduce operational efficiency.
3Reliability
If authentication-free devices are not supported, then authentication security is maintained, but adaptability deteriorates
Solution Approach 1:
The patent applies local quality by creating two distinct authentication pathways: one for devices requiring cryptographic authentication and another for authentication-free devices. The control device determines which pathway to use based on device characteristics, allowing the system to adapt to different device types while maintaining security for devices that require it. This resolves the contradiction by providing both secure authentication for needed devices and compatibility for devices that don't require authentication.

AI summary
The present invention relates to a control method for authentication of a connection device connected to a network, in particular a network mounted on a boat, comprising the steps of: performing an authentication-free determination to determine whether or not the connection device corresponds to an authentication-free device, performing an authenticating action with the connection device if the connection device does not correspond to an authentication-free device, and exempting the connection device from the authenticating action if the connection device corresponds to an authentication-free device, and to a control device for a boat.
