This paper proposes a new solution to the pseudonym certificate management and usage in Vehicle-to-Everything (V2X) communication. This solution is a result of our critical analysis of the Issue First Activate Later (IFAL) pseudonym certificate management scheme, which is mentioned in an ETSI Intelligent Transport System (ITS) pre-standardization document. While the IFAL scheme improves over the existing ETSI ITS Security Credential Management System (CCMS) for Europe and the Security Credential Management System (SCMS) for the US, it still has significant issues when real-world deployment is considered. To address these issues, we propose a novel activation scheme that improves the security properties by combining the OAuth concept and Authentication Encryption with Associated Data (AEAD) solution to provide confidentiality and authenticity of data. Our analysis and simulation show that our scheme significantly improves the security properties and efficiency of certificate usage. As a result, our solution is more robust, reliable, and efficient. We propose this solution for adoption in the ETSI ITS specifications.
