The X.509 trust model is based on three entities: the certification authority (CA), the certificate holder and the relying party (RP). The CA plays the role of a trusted third party between the certificate holder and the RP. It guarantees to the RP the correctness of the certificate information. This trust model is based on hypothesis that RPs have a predefined trust relation with a CA and that the trust level in CA can be determined by reading and analyzing a set of technical and legal documents. The X.509 trust model is so complex to RPs because an RP must realize this task for each and every CA chosen by the certificate holders. We introduce a new role of technical and legal expert into the X.509 trust model to help the RP make this task.
