Patent attributes
A cloaking authority system that securely and anonymously identifies a misbehaving device based on its digital certificate. The system may include a cloaking authority server that is communicatively connected to a misbehavior authority server, a pseudonym certificate authority device, and a registration authority device. In response to a request from the misbehavior authority server to identify a misbehaving device using the device's pseudonym certificate, the cloaking authority server interacts with the pseudonym certificate authority device and the registration authority device to securely obtain a representation of the linkage chain identifier that is associated with the misbehaving device, while maintaining the anonymity of the real-world identifying information for the misbehaving device. The cloaking authority server creates a cloak index that corresponds to the linkage chain identifier and that identifies the misbehaving device, and provides the cloak index to the misbehavior authority server.
