But, not all PKIs need adopt this sort of CA model, in which relying parties are required to make value judgments about the trustworthiness of the organizations that operate CAs. PKIs are not intrinsically valuable. They are infrastructures that, if successful, facilitate authentication and authorization services based on the use of public key cryptography.
