Secure Bootstrapping Service for V2X Key Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security measures for vehicle-to-everything (V2X) communication lack standardized methods for secure and automated bootstrapping of keys and certificates, particularly between a device configuration manager (DCM) and end entities, which increases the risk of private key leakage and manual installation vulnerabilities.
Innovation Solution
The introduction of a secure bootstrapping service (SBS) within the security credential management system (SCMS) for V2X communication, utilizing an SBS agent and server to automate the bootstrapping process through HTTPS communication, encrypting messages, and verifying certificates to prevent key leakage and enhance security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual bootstrapping process is used between DCM and EE, then flexibility in key management is maintained, but security risk of private key leakage increases and automation is reduced
Solution Approach 1:
The patent introduces an SBS server as an intermediary component between the DCM and EE. The SBS server receives bootstrapping requests from the DCM, manages the bootstrapping data, and securely provides it to the EE through the SBS agent. This intermediary structure automates the key management process while maintaining security controls, resolving the contradiction between automation and security.
Solution Approach 2:
The patent enables the EE to perform self-service bootstrapping through the SBS agent, which automatically retrieves and installs bootstrapping data from the SBS server without requiring manual intervention. This self-service mechanism achieves full automation while maintaining security through standardized cryptographic protocols and secure data transmission channels.
2Reliability
If standardized secure bootstrapping is implemented through SBS, then security is enhanced and automation is achieved, but system complexity increases
Solution Approach 1:
The patent designs the SBS server and SBS agent as universal components that can serve multiple end entities with different requirements. The SBS server provides a standardized interface for all bootstrapping operations, while the SBS agent implements a generic secure bootstrapping mechanism that adapts to various EE types. This universality reduces system complexity by avoiding the need for custom bootstrapping solutions for each EE.
Solution Approach 2:
The patent uses parameter changes to manage complexity, specifically by configuring the SBS agent with different end entity codes that determine the type of bootstrapping data to retrieve and install. This parameter-based configuration allows the same standardized mechanism to serve multiple purposes without increasing structural complexity.
3Productivity
If automated bootstrapping is implemented, then installation efficiency is improved, but security vulnerabilities in automated processes may increase
Solution Approach 1:
The patent implements preliminary anti-action by establishing secure cryptographic protocols and validation mechanisms before the actual bootstrapping data transmission occurs. The SBS agent verifies the authenticity and integrity of bootstrapping data from the SBS server using digital signatures and certificate validation, preventing security vulnerabilities before they can exploit the automated process.
Solution Approach 2:
The patent incorporates feedback mechanisms where the SBS agent reports bootstrapping status and verification results back to the SBS server. This feedback loop enables real-time security monitoring and validation, ensuring that automated bootstrapping operations maintain security standards while achieving high installation efficiency.
