Intelligent Transportation Systems that rely on Vehicle-to- Cloud communications are emerging. Of particular inter- est to us is the question how drivers can securely register their vehicle with cloud services and deploy keys for secur- ing vehicular communications. We therefore present a secure smartphone-based registration and key deployment process for these applications. We combine an adapted OAuth flow for Smartphone-to-Cloud communications with a novel key deployment mechanism for Public Key Infrastructures in ve- hicular networks. The primary contributions of the proposed key deployment process are a high degree of independence from central authorities and feasible security audits due to an open protocol design. As an instance of future Intelligent Transportation System applications that facilitate Vehicle- to-Cloud communications, we utilize the V-Charge project as a running example to discuss potential attack scenarios and their mitigations.
