<p>A key certificate generation system used for home gateway is provided by the invention. In the above described system, a key certificate management server (30) interacts with an encryption machine (40), based on the requests submitted by a management terminal (10) and a commercialization data obtaining terminal (20), executes the operations of generating a root key and a root certificate, exporting the root certificate, generating a version signed key, signing version data, generating the key and certificate of the home gateway, and so on; the generated root certificate is exported to the management terminal (10), the signed version data is returned to the commercialization data obtaining terminal (20), the generated key and certificate of the home gateway are returned to the commercialization data obtaining terminal (20), the public key corresponding to the version signed private key is exported and returned to the commercialization data obtaining terminal (20). According to the invention, the security of the communication can be ensured, the confidentiality and integrity of the information transmission can be guaranteed, and the validity of the identity can be guaranteed.</p> |
