Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle security infrastructure lacks effective cryptographic signing techniques to authenticate processes interacting with autonomous vehicles, leading to potential security breaches and loss of trust among processes.
Innovation Solution
A vehicle computing system with a master device that includes an orchestration service to start processes and a master host security service to authenticate processes, using cryptographic signing techniques to generate and manage root certificates and process manifests, ensuring secure communication between processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cryptographic signing techniques are implemented to authenticate processes, then security and trust among processes is improved, but device complexity increases due to additional security services and certificate management
Solution Approach 1:
The patent introduces a master host security service as an intermediary that centralizes certificate authority functions. This master security service generates root certificates and issues signed certificates to other host security services, which in turn authenticate processes. This intermediary approach consolidates complex cryptographic operations in a centralized authority, reducing the burden on individual process-authenticating components while maintaining strong security through hierarchical certificate validation.
2Device complexity
If a centralized master device manages all certificates, then security management is simplified, but the system becomes more vulnerable to single points of failure and attacks
Solution Approach 1:
The patent segments the certificate management function into two distinct roles: a master host security service that generates and manages root certificates, and requesting host security services that obtain and use signed certificates for process authentication. This segmentation allows centralized certificate generation while distributing the authentication function across multiple hosts, reducing the single point of failure risk as compromised requesting hosts cannot generate new certificates, only validate existing ones.

AI summary
Systems and methods for onboard vehicle certificate distribution are provided. A system can include a plurality of devices including a master device for authenticating processes and one or more requesting devices. The master device can include a master host security service configured to authenticate the one or more processes of the system. The master host security service can run a certificate authority to generate a root certificate and a private root key corresponding to the root certificate. A respective host security service can receive a request for a process manifest for a requesting process of a respective device from a respective orchestration service. The respective host security service can generate the process manifest for the requesting process and provide the process manifest to the requesting process. The requesting process can use the process manifest to communicate with the certificate authority to obtain an operational certificate based on the root certificate.
