Claim 11:
12. The method according to claim 4, wherein the issuing a proxy node initiation identity certificate to the proxy node through the first-tier certificate authority node further comprises:
generating an initiation public key and an initiation private key of the proxy node by using the first-tier certificate authority node;
generating the proxy node initiation identity certificate for the proxy node, the proxy node initiation identity certificate comprising the initiation public key of the proxy node; and
transmitting the proxy node initiation identity certificate and the initiation private key of the proxy node to the proxy node; and
wherein the receiving the proxy node communication identity certificate issuance request further comprises:
receiving the proxy node initiation identity certificate from the proxy node;
receiving the proxy node communication identity certificate issuance request from the proxy node, the proxy node communication identity certificate issuance request comprising registration information of the proxy node and a signature signed to the registration information of the proxy node by using the initiation private key of the proxy node; and
performing, by using the initiation public key of the proxy node in the proxy node initiation identity certificate, verification on the signature in the proxy node communication identity certificate issuance request; and

wherein the issuing the proxy node communication identity certificate to the proxy node through the second-tier certificate authority node further comprises:
performing authentication on the registration information of the proxy node by using the second-tier certificate authority node;
generating a communication public key and a communication private key of the proxy node for the proxy node when the authentication succeeds;
generating the proxy node communication identity certificate for the proxy node, the proxy node communication identity certificate comprising the communication public key of the proxy node; and
transmitting the proxy node communication identity certificate and the communication private key of the proxy node to the proxy node, the proxy node communication identity certificate and the communication private key of the proxy node being used for the proxy node to communicate with the service node.
