Geolocation-Specific Application Certificates for V2X RSU Provisioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for provisioning digital assets to V2X infrastructure devices, such as roadside units, face challenges in ensuring geolocation-specific and up-to-date software, as conventional methods require physical re-provisioning and are inefficient, especially for portable devices with changing geolocation needs.
Innovation Solution
An enhanced Security Credential Management System (SCMS) that generates and provides geolocation-specific application certificates, allowing devices to operate within precise geographic restrictions, enabling secure and efficient updating of digital assets without the need for physical re-provisioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If physical re-provisioning is used to update digital assets on V2X devices, then security credentials can be updated, but the process becomes inefficient and requires physical access to devices
Solution Approach 1:
The patent replaces the mechanical/physical provisioning process with a digital/cryptographic system. Instead of physically accessing devices to update credentials, the system uses secure cryptographic protocols (SCMS, certificates, keys) to enable remote, automated updating of digital assets, thereby eliminating the need for physical re-provisioning while maintaining security.
2Measurement precision
If geolocation-specific digital assets are provisioned to portable devices with changing locations, then operational accuracy is improved, but the complexity of managing location-specific credentials increases
Solution Approach 1:
The patent implements dynamic geolocation-based credential management where digital assets and operational permissions are automatically adjusted based on the device's current location. The system dynamically determines whether a device is within its authorized geo-region and adjusts access rights accordingly, eliminating the need for manual management of location-specific credentials while maintaining precise geolocation control.
Solution Approach 2:
The system continuously monitors the geolocation of portable devices and provides feedback to automatically adjust operational permissions. By integrating GPS/location services with the credential management system, the platform can automatically verify whether a device is within its authorized region and enforce appropriate access controls without manual intervention.
3Loss of time
If conventional provisioning methods are used for V2X infrastructure devices, then initial setup is possible, but updates require physical access and are time-consuming
Solution Approach 1:
The patent enables self-service credential updates through the SCMS platform. Devices can automatically request and receive updated digital assets through secure communication channels without requiring physical access or manual intervention. The system autonomously manages the provisioning lifecycle, including initial provisioning, updates, and revocation, significantly reducing the time and manual effort required.

AI summary
Systems, methods, and devices for securely provisioning a roadside unit (RSU) that includes an application certificate, wherein the RSU is geographically restricted according to the application certificate. An enhanced SCMS system may receive a request for an application certificate for the RSU; determine, in response to the request, an operating geolocation for the RSU; verify that the operating geolocation is within the allowed geo-region for the RSU; generate an application certificate that includes the operating geolocation; and provide the application certificate to the RSU device. Also provided is an application certificate that includes precise operating geolocation information, an improved application certificate provisioning request that allows the requestor to specify a precise operating geolocation, new processes for generating and providing improved application certificates having geographic-restriction information, an enhanced SCMS that performs the processes, and improved computerized devices, such as RSUs, that employ the precise, operating geolocation information from the application certificates.
