According to the present invention, one or more information sets for authenticating the mobile phone as an OTP medium through a communication network are stored (or set) in a universal subscriber identity module (USIM) or a memory area of a user mobile phone used as an One Time Password (OTP) medium. Thereafter, by using the mobile phone as an OTP medium, the OTP generated by OTP medium authentication information including at least one of the information sets stored in the USIM / memory and the terminal-side OTP generation information to the server on the communication network. The server on the communication network authenticates the mobile phone as a valid OTP medium, and OTP generation information combining the server-side OTP generation information corresponding to the index value dynamically determined by the mobile phone according to the OTP medium authentication result and the OTP provided from the mobile phone. When the N-digit OTP is generated and provided to the mobile phone through the mobile phone, To provide a method and a system for output to receive the digit of N OTP.

With the development of information and communication technology, non-face-to-face transactions using telecommunication networks are activated, non-face-to-face transaction providers must verify that users connected through telecommunication networks are valid traders and prepare for any incidents that may occur.

In the non-face-to-face transaction as described above, the most common method of authenticating a user connected through a communication network is used to authenticate using ID / PW. It is used to identify the trader rather than being used.

As a non-face-to-face transaction authentication method that is more advanced than the ID / PW method, an authentication method using an official certificate is used, and a medium (for example, a computer) on which the official certificate is recorded is hacked, When processing a non-face-to-face transaction through the installed terminal, the official certificate also has a problem that does not provide a reliable degree of face-to-face transaction authentication.

One time password (OTP) is used as a method for solving the problems of the above-mentioned public certificate. The OTP is one or more fixed seed value and a fixed seed value that is dynamically determined at the time of generating the password, the non-faceted trading party exchange / share, and then each of the trading party is confirmed / determined at the non-faceted authentication Substituting the seed value and the dynamic seed value into a predetermined code generation algorithm (eg, a hash function) to generate an OTP that can be used once, and exchanging and authenticating the generated OTP, even if the OTP is exposed, reuses the same OTP. Since it is not possible to use, it is used as an authentication means that is safer against hacking than other authentication means.

As described above, in order to generate an OTP, a user has to carry a portable device called an OTP generator. Recently, an OTP generator program (for example, an OTP generator algorithm) is implemented in a mobile phone that the user always owns. It is proposed to install a program code and seed value and use it as an OTP generator.

However, the conventional mobile phone OTP generator implements the OTP generator in the form of a portable device in the form of program code on a mobile phone. The OTP generating program installed in the mobile phone OTP generator is copied to another mobile phone (for example, a copy through a serial communication connection). Or, when replicating a mobile phone in which the OTP generating program is installed, the mobile phone OTP generator has a problem that it is no longer reliable.

In addition, when using a wireless non-face-to-face transaction such as wireless payment / banking through a mobile phone used as the mobile phone OTP generator, the mobile phone is used as a transaction medium for the non-face-to-face transaction as well as an authentication medium for authenticating the non-face-to-face transaction. In this case, such wireless face-to-face transactions do not meet the Two-Factor Authentication requirement that the transaction and authentication media must be separated into different media in face-to-face transactions with OTP authentication. I have a problem.

An object of the present invention for solving the above problems is to provide at least one information set for authenticating the mobile phone to the OTP medium through a communication network in a universal subscriber identity module (USIM) or a memory area of a user mobile phone used as the OTP medium.

Receiving the N-digit OTP input through the OTP input interface output to the 205, or receives the generated N-digit OTP from the mobile phone 200 shown in Figure 1 (500), the storage medium ( From the M terminal OTP generation information corresponding to the OTP medium that generated the N-digit OTP from 275, the index value confirmed through the process shown in FIG. 4 is provided. Otherwise, the terminal-side OTP generation information and the server-side OTP generation information are checked (505).

When the N-digit OTP is received from the user terminal 205 according to an embodiment of the present invention, the unique information of the mobile phone 200 corresponding to the OTP medium is an OTP authentication request before the N-digit OTP is received. It may be provided to the server in the process, or to the server with the N-digit OTP.

When the N-digit OTP is received from the user terminal 205 according to another embodiment of the present invention, the unique information of the mobile phone 200 corresponding to the OTP medium is determined from caller information corresponding to the mobile phone 200. It is preferred that it is identified or provided to the server with the N-digit OTP.

Thereafter, the server generates an OTP generation value through the terminal-side OTP generation information, and configures the OTP generation information by combining (or linking) the OTP generation value and the server-side OTP generation information (510).

If the server can check the OTP generation information generated by the N-digit OTP provided to the mobile phone 200 through the process shown in Figure 4, the server provides the N-digit number provided to the mobile phone 200 It is possible to check the OTP generation information that generated the OTP.

According to another embodiment of the present invention, when the OTP generation information provided to the mobile phone 200 includes an OTP generation value generated through the server-side OTP generation information, the server may generate an OTP through the terminal-side OTP generation information. After generating a generation value and generating an OTP generation value through the server-side OTP generation information, the OTP generation information may be configured by combining (or linking) each generated OTP generation value.

Thereafter, the server confirms one or more fixed seed values for generating the N-digit OTP 'from the OTP generation information, determines one or more dynamic seed values through the parameters included in the OTP generation information, and the identification. The determined one or more fixed seed values and dynamic seed values are substituted into a predetermined OTP generation algorithm to generate N digits of OTP '(515).

If the server can identify the N-digit OTP provided to the mobile phone 200 through the process shown in FIG. 4, the server checks the N-digit OTP provided to the mobile phone 200. It is possible.

If the N-digit OTP 'is generated (520), the server compares (or verifies) the received N-digit OTP' to verify the OTP validity (525).

According to the exemplary embodiment of the present invention, if the result of the comparison between the OTP and the OTP 'is matched (or matched) or a pre-predicted result is obtained through a verification operation, the server verifies the validity of the OTP. Treat it as done.

If the OTP validity is not confirmed (530), the server receives a predetermined OTP authentication result receiving means (for example, OTP authentication request server 215, user terminal 205, mobile phone) (Including one or more of 200) (535).

On the other hand, if the OTP validity is confirmed (530), the server receives the OTP authentication result corresponding to the OTP validity check means (for example OTP authentication request server 215, user terminal 205, mobile phone) One or more of 200) (540).

According to the present invention, one or more information sets for authenticating the mobile phone as an OTP medium through a communication network are stored (or set) in a universal subscriber identity module (USIM) or a memory area of a user mobile phone used as an OTP medium, Whenever OTP is used as an OTP medium, OTP medium authentication information including at least one of the information sets stored in the USIM / memory is transmitted to a server on a communication network so that the mobile phone can be authenticated as a valid OTP medium. Whenever it is generated, there is an advantage of continuously verifying and maintaining the reliability of the OTP generated through the mobile phone by authenticating whether the mobile phone is a valid OTP medium.

According to the present invention, when the mobile phone is authenticated as a valid OTP medium, OTP generation information combining the server-side OTP generation information corresponding to the index value dynamically determined by the mobile phone in the server on the communication network and the OTP provided from the mobile phone is provided. By generating an N-digit OTP through the mobile phone, by receiving and outputting the N-digit OTP from the mobile phone, the N-digit OTP is generated and output only by the mobile phone registered as a valid OTP medium, Regardless of whether the mobile phone is used as a non-face-to-face transaction medium, there is an advantage of always satisfying two-factor authentication conditions.
