Central Gateway Security Architecture for Vehicle Data and Network Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems for central gateways in intelligent vehicles are not comprehensive enough to address the increasing threats from network attacks, data tampering, and malicious code implantation, necessitating advanced security solutions for secure in-vehicle and out-vehicle communication.
Innovation Solution
A multi-layered security architecture for central gateways comprising an application security layer, data security layer, network security layer, node security layer, identity and authentication management layer, and security operation and maintenance layer, with specific modules for each layer to ensure comprehensive security protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a comprehensive multi-layered security architecture is implemented, then security protection capability is improved, but system complexity increases
Solution Approach 1:
The security architecture is divided into six distinct layers: application security layer, data security layer, network security layer, node security layer, identity and authentication management layer, and security operation and maintenance layer. Each layer addresses specific security concerns and can be independently configured and maintained, making the comprehensive security system manageable despite its complexity
Solution Approach 2:
The central gateway is designed to perform multiple functions including data exchange, security management, identity authentication, and network control. This multi-functional approach consolidates security capabilities into a single platform, improving security protection while avoiding the need for multiple separate security systems that would increase overall complexity
2Reliability
If security management and authentication modules are added, then security control is improved, but processing efficiency decreases
Solution Approach 1:
Identity authentication and security policies are pre-configured in the central gateway before actual data transmission occurs. This allows security checks to be performed more efficiently during runtime, as the framework and authentication rules are already in place rather than being established during each transmission event
Solution Approach 2:
The central gateway acts as an intermediary between the external network and in-vehicle networks, centralizing security management functions. This mediation approach improves security control by providing a single point of security enforcement, while potentially improving efficiency by avoiding redundant security checks across multiple distributed security nodes

AI summary
The present disclosure relates to the technical field of intelligent gateway security, in particular to a security architecture and system for a central gateway, and a storage medium. The security architecture includes an application security layer, a data security layer, a network security layer, a node security layer, an identity and authentication management layer, and a security operation and maintenance layer; wherein the application security layer is used to ensure the security of application software; the data security layer is used to ensure the security of data passing through a central gateway; the security of in-vehicle and out-vehicle network communication of the central gateway is ensured by the network security layer; the node security layer is a support carrier for the application security layer, the data security layer, and the network security layer; and the identity and authentication management layer and the security operation and maintenance layer are both applied to the application security layer, the data security layer, the network security layer, and the node security layer. The central gateway is not only a simple data exchange center, but also has data and computing power, and provides common functions of a sharing service, central management, central control, and the like for a complete vehicle; and the central gateway in the present disclosure has double-layer protection of local data security and data transmission security.
