1. A terminal unique information transmission method comprising:
receiving, by a server, from a terminal, a terminal unique information acquisition request including a terminal unique public key certificate of the terminal; generating an encrypted terminal unique public key certificate by encrypting the terminal unique public key certificate of the terminal; checking, by the server, whether the generated encrypted terminal unique public key certificate is described in a discarded terminal information table; transmitting, by the server, when the generated encrypted terminal unique public key certificate is not described in the discarded terminal information table, a terminal unique information of the terminal to the terminal; receiving, by the server, from the terminal, a terminal unique information update request including an other encrypted terminal unique public key certificate obtained by encrypting a terminal unique public key certificate of an other terminal and a restoration destination terminal certificate list in which at least the terminal unique public key certificate of the terminal is described as a latest element; checking, by the server, whether the other encrypted terminal unique public key certificate is described in a terminal unique information table; and transmitting, by the server, when the other encrypted terminal unique public key certificate is described in the terminal unique information table, the terminal unique information associated with the other encrypted terminal unique public key certificate to the terminal and describing the other encrypted terminal unique public key certificate in the discarded terminal information table. |
