| 摘要 |
The present invention relates to a method for transferring a certificate from a stationary terminal to a movable terminal. The stationary terminal receives an identifier of the mobile terminal and an authentication code which is randomly generated by the mobile terminal. The stationary terminal generates a one-time base key and one-time public information. The stationary terminal generates an intermediate secret key and an initial vector. The stationary terminal generates an encryption key and a message authentication code key. The stationary terminal encodes the certificate. The stationary terminal generates a message authentication code. The stationary terminal transmits the identifier, the encoded certificate, the message authentication code, and the one-time public information to a certificate transmission server.
