PURPOSE: A server type of a one-time authentication code implementation method through medium authentication is provided to implement a combination type or completion type of a one-time authentication code in response to the medium authentication for a wireless terminal, thereby enabling the using of the one-time authentication code. CONSTITUTION: A server generates authentication code generation information for generating an authentication code in a wireless terminal corresponding to an authentication code generation rule by connecting a storage medium(600). The server generates an authentication code through the generated authentication code generation information(605). When the authentication code is generated, the server transmits the authentication code to the wireless terminal through a communication channel(610,615). The wireless terminal receives the authentication code through a communication channel(620). The wireless terminal generates the authentication code through the authentication code generation information(625). When the authentication code is generated, the wireless terminal generates a new authentication code by combining the authentication code and displays the new authentication code on a screen of the wireless terminal(630,635,640). [Reference numerals] (600) Server generates authentication code(N-n) generation information by being connected to a storage medium; (605) Server generates an authentication code(N-n) through the generated authentication code generation information; (610) Is the generation of the authentication code(N-n) confirmed?; (615) Server transmits the authentication code(N-n) to a wireless terminal through a communication channel; (620) Wireless terminal receives the authentication code(N-n) through the communication channel; (625) Wireless terminal generates an authentication code(n) through authentication code(n) generation information; (630) Is the generation of the authentication code(n) confirmed?; (635) Wireless terminal generates an authentication code(N) by combining the authentication code(n) and the authentication code(N-n); (640) Wireless terminal outputs the authentication code(N) generated by the combination on a screen; (AA,CC) No; (BB,DD) Yes; (EE) End
