Service Access Authentication for Cross-Platform Vehicle ECUs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of ensuring secure service access in a networked intelligent vehicle environment, where different electronic control units (ECUs) and controllers with varying operating systems and deployment platforms require robust security control for cross-vehicle, cross-platform, and cross-system service access.
Innovation Solution
A service access method that involves obtaining identifiers from system data and access requests, determining authentication results, generating access requests based on these identifiers, and utilizing authentication management units and security components to verify permissions, thereby enhancing the reliability and validity of access requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If service access permission verification is performed before service request, then service access security is improved and invalid requests are reduced, but system complexity and processing time increase
Solution Approach 1:
The patent implements permission verification before service request by obtaining the first identifier from system data and the second identifier from the access request, then determining authentication results in advance. This preliminary action filters invalid requests before they reach the service providing unit, improving security while managing complexity through structured identifier handling.
Solution Approach 2:
The patent introduces an authentication management unit as an intermediary between the service requesting unit and the service providing unit. This intermediary handles the complex permission verification process, including obtaining identifiers, determining authentication results, and generating second access requests, thereby isolating complexity from the core service provision logic.
2Reliability
If authentication management unit is introduced to verify permissions, then service access authenticity is improved, but communication overhead and processing time increase
Solution Approach 1:
The authentication management unit performs permission verification in advance by obtaining identifiers and determining authentication results before the service request is fully processed. This preliminary authentication reduces the need for repeated verification later in the process, potentially offsetting the initial time cost.
Solution Approach 2:
The patent extracts the authentication logic into a separate authentication management unit, which handles identifier obtaining, authentication result determination, and permission verification. This extraction allows the core service provision process to focus on its primary function while authentication is handled by a specialized component.
Data Source
AI summary
A service access method and an apparatus are disclosed. The method includes: obtaining, from system data, a first identifier corresponding to a service requesting unit; obtaining, from a first access request, a second identifier corresponding to a service, where the first access request indicates that the service requesting unit requests the service from a service providing unit; determining an authentication result based on the first identifier and the second identifier, where the authentication result indicates whether the service requesting unit has a permission to access the service; when the authentication result indicates that the service requesting unit has the permission to access the service, generating a second access request; and sending the second access request to the service providing unit.
