摘要

A method of transmitting / receiving data between a mobile terminal and an OTP generator and a keylock module in a process of authenticating a password and a keylock module of the OTP generator of the present invention includes: a step of receiving an OTP application module and an OTP application module of the OTP generator, (S12) of transmitting the OTP generator or keylock module selection command to the smart card (S12); and a step (S12) of executing the OTP generator or the keylock module selection command based on the command received by the smart card (Step S13). If the OTP generator is selected in step S13, the OTP generator is activated to generate a one-time private number and transmit the generated one-time private number to the mobile terminal. Transmitting the authentication result to an institution server and receiving an authentication resu Generating a key value on the basis of the key lock module selection command received by the smart card, transmitting the key value generated by the smart card to the mobile terminal, And transmitting a key value to an authentication authority server for authentication.;
