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.
