<p>The present invention discloses a system for generating a key certificate used for a home gateway. In the system, a key certificate management server interacts with an encryption machine to perform operations of generating a root key and a root certificate, exporting the root certificate, generating a key of version signature and a version data signature, and generating a key and a certificate of the home gateway, according to requests submitted by a management terminal and a product-like data acquisition terminal; exports the generated root certificate to the management terminal, returns the signed version data to the product-like data acquisition terminal, returns the generated key and the certificate of the home gateway to the product-like data acquisition terminal, and exports a public key corresponding to a private key of version signature and returns the public key to the product-like acquisition terminal. According to the present invention, it can be realized to ensure the communication security, the secrecy and integrity of information transmission, and the authenticity of the identification.</p> |
