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 or device that is communicatively connected to a misbehavior authority server, and may also include a pseudonym certificate authority device, and a registration authority device. The cloaking authority device receives, from the misbehavior authority server, a request for a cloak index, wherein the request for the cloak index includes the linkage value from a PC of a misbehaving computerized device. The cloaking authority device processes the linkage value to produce a cloak index, which identifies the misbehaving computerized device and which is unique and anonymous, and transmits it to the requesting misbehavior authority server. The misbehavior authority server uses the cloak index to identify the specific computerized device that has misbehaved, usually repeatedly.
