Claim 15:
16. The certificate authority system of claim 15, wherein the certificate authority system is configured to issue the third identity certificate by:
issuing, when the third identity certificate issuance request is for a service node unit, the service node unit identity certificate to the second terminal, so that the second terminal forwards the service node unit identity certificate to the service node unit terminal, the service node unit identity certificate being used for communication of chained information between the service node and the proxy node;
issuing, when the third identity certificate issuance request is for a non-service node unit, the non-service node unit identity certificate to the second terminal, so that the second terminal forwards the non-service node unit identity certificate to the non-service node unit terminal, the non-service node unit identity certificate being used for transfer of basic information of the chained information between the non-service node unit terminal and the service node unit terminal; and
issuing, when the third identity certificate issuance request is for an individual, the personal identity certificate to the second terminal, so that the second terminal forwards the personal identity certificate to the personal terminal, the personal identity certificate being used for transfer of the basic information of the chained information between the personal terminal and the service node unit terminal.
