摘要：
To revoke a digital certificate, activation of the digital certificate is blocked by withholding an activation code from the certificate user. The certificates are generated by a plurality of entities in a robust process that preserves user privacy (e.g. anonymity) even in case of collusion of some of the entities. The process is suitable for connected vehicles, e.g. as an improvement for Security Credential Management System (SCMS).
