Vehicle Proxy for Secure External Network Access

The patent introduces a proxy as an intermediary component that sits between external communication systems and internal vehicle electronic components. The proxy receives communication requests from external entities, validates them against security policies, and forwards authorized requests to the appropriate vehicle components. This mediator architecture enables external communication capability while preventing direct unauthorized access to internal components, thus resolving the contradiction between communication versatility and security risk.

The patent extracts the security policy enforcement functionality from the individual vehicle electronic components and consolidates it into a centralized proxy. Instead of each component implementing its own access control logic, the proxy alone handles security policy evaluation and access decisions. This extraction reduces the complexity burden on individual components while maintaining comprehensive security protection through centralized policy management.

The proxy serves as an intermediary that maintains ease of operation for authorized users while blocking unauthorized access. The proxy transparently handles authorized requests by forwarding them to the appropriate vehicle components without adding noticeable delay or complexity for legitimate users. Simultaneously, it intercepts and blocks unauthorized requests before they reach internal components, thus preserving operational convenience while eliminating unauthorized access risk.
