도 2는 본 발명에 따른 게임 실행 권한 인증 방법을 설명하는 절차 흐름도이다. 도 1 및 도 2를 참조하여, 본 발명에 따른 게임 실행 권한 인증 방법을 설명하면, 먼저, 게임실행 장치(100)는 인증 서버(200)에 접속하여 게임을 실행시키기 위해 필요한 복호화 키의 전송을 요청한다(S300). 2 is a flowchart illustrating a game execution authority authentication method according to the present invention. Referring to FIGS. 1 and 2, the game execution authority authentication method according to the present invention will be described first. First, the game execution apparatus 100 connects to the authentication server 200 and transmits a decryption key required to execute a game. Request (S300).

여기서, 복호화 키는 게임실행 장치(100)에 저장되어 있는 암호화된 실행 파일을 복호화하기 위해 필요한 키이며, 암호화된 실행 파일은 게임실행 장치(100)에 설치되어 있는 사용자가 원하는 게임을 실행시키기 위해 필요한 실행 파일로써, 해당 복호화 키에 의해 암호화된 실행 파일을 의미한다. Here, the decryption key is a key necessary for decrypting the encrypted executable file stored in the game execution device 100, the encrypted executable file is to run the game desired by the user installed in the game execution device 100 As an executable file, it means an executable file encrypted by the corresponding decryption key.

On the other hand, the authentication server 200, if there is a request for transmission of the decryption key from the game execution device 100, after the authentication process of the user through the user ID connected to the authentication server 200 after the game execution device The decryption key is transmitted to 100.

이에 게임실행 장치(100)는 인증 서버(200)로부터 복호화 키를 수신하게 되며(S305), 수신한 해당 복호화 키를 이용하여 전술한 암호화된 실행 파일을 복호화하여 실행 파일을 생성하게 된다(S310). Accordingly, the game execution device 100 receives a decryption key from the authentication server 200 (S305), and decrypts the above-mentioned encrypted executable file using the received decryption key to generate an executable file (S310). .

그 다음, 게임실행 장치(100)는 게임실행 장치(100)에서 측정되고 있는 현재 시간(Present Time:PT)을 획득하며, 난수 발생 모듈을 통해 랜덤 데이터(Random Data:RT)를 생성하고(S315), 일방향 해쉬함수를 이용하여, 획득된 현재시간과 생성된 랜덤 데이터를 함께 해쉬함으로써 소정의 해쉬 데이터(Hashed Data)를 생성하게 된다(S320).Next, the game execution device 100 obtains the present time (Present Time: PT) being measured by the game execution device 100, generates random data (Random Data: RT) through the random number generation module (S315). By using the one-way hash function, predetermined hash data is generated by hashing the acquired current time and the generated random data together (S320).

그 다음에 게임실행 장치(100)는 전술한 S315 단계에서의 현재시간과 랜덤 데이터를 전술한 S320 단계에서 생성된 해쉬 데이터와 함께 임의의 고정키로 암호화함으로써 암호화 데이터를 생성하게 된다(S325).Next, the game execution apparatus 100 generates encrypted data by encrypting the current time and random data in the above-described step S315 with an arbitrary fixed key together with the hash data generated in the above-mentioned step S320 (S325).

이와 같이 생성된 암호화 데이터는 전술한 S310 단계에서 생성된 실행 파일에 인수로 전달된다(S330).The generated encrypted data is transferred as an argument to the executable file generated in the above-described step S310 (S330).

본 발명에 따른 게임실행 장치(100)는 실행 파일을 이용하여 게임을 실행하기에 앞서 다음과 같은 두단계의 인증과정을 거치게 된다. The game execution apparatus 100 according to the present invention undergoes the following two steps of authentication process before executing a game using an executable file.

-1차 인증과정-1st certification process

먼저, 게임실행 장치(100)는 전술한 S325 단계에서 임의의 고정키로 암호화하여 생성한 암호화 데이터를 해당 고정키를 이용하여 복호화함으로써 전술한 S315 단계에서의 현재시간, 및 랜덤 데이터와 전술한 S320 단계에서 생성된 해쉬 데이터를 얻는다(S335).First, the game execution apparatus 100 decrypts the encrypted data generated by encrypting with a certain fixed key in the above-described step S325 by using the corresponding fixed key, the current time in the above-described step S315, and the random data and the above-described step S320. Hash data generated in step S335 is obtained.

그 다음, 게임실행 장치(100)는 전술한 S335 단계에서 획득한 현재시간, 및 랜덤 데이터를 일방향 해쉬 함수를 이용하여 다시 해쉬함으로써 해쉬값(Hashed Value:HV)을 생성하고(S340), 생성된 해쉬값과 전술한 S335 단계에서 획득한 해쉬 데이터와의 일치여부를 확인한다(S345).Next, the game execution apparatus 100 generates a hash value (HV) by hashing again the current time and the random data obtained in the aforementioned step S335 using a one-way hash function (S340). It is checked whether the hash value coincides with the hash data acquired in the above-described step S335 (S345).

한편, 본 발명을 실시함에 있어서는, 본 발명에 따른 게임 실행 권한 인증 프로그램이 인증 서버(200)로부터 게임실행 장치(100)로 전송되는 경우에 전술한 고정키 및 일방향 해쉬함수 또한 함께 전송되도록 하는 것이 바람직할 것이며, 인증 서버(200)는 각 사용자별로 각기 다른 고정키 및 일방향 해쉬함수를 게임실행 장치(100)에 전송하는 것이 바람직할 것이다. On the other hand, in the practice of the present invention, when the game execution authority authentication program according to the present invention is transmitted from the authentication server 200 to the game execution apparatus 100, the fixed key and the one-way hash function described above are also transmitted. It will be preferable, the authentication server 200 it is preferable to transmit a different fixed key and one-way hash function for each user to the game execution apparatus 100.

만약, 전술한 S310 단계에서 생성된 실행 파일 및 전술한 S325 단계에서 생성된 암호화 데이터가 다른 사용자의 게임실행 장치(100)로 불법 복사된 경우라면, 불법 복사된 실행 파일 및 암호화 데이터를 저장하게 된 다른 사용자의 게임실행 장치(100)에는 전술한 고정키 및 일방향 해쉬함수가 구비되어 있지 않을 것이므로, 전술한 S345 단계에서 일치여부를 확인한 결과 불일치한 것으로 판단될 것이다. 이러한 경우에는 해당 게임의 실행은 취소된다(S350).If the executable file generated in the above-described step S310 and the encrypted data generated in the above-described step S325 are illegally copied to the game execution apparatus 100 of another user, the illegally copied executable file and the encrypted data are stored. Since the game execution apparatus 100 of the other user does not have the above-described fixed key and one-way hash function, it will be determined that the result is inconsistent as a result of checking the match in the aforementioned step S345. In this case, execution of the game is canceled (S350).

그러나, 전술한 S300 단계 내지 S345 단계가 하나의 게임실행 장치(100)에서 수행된 경우라면, 전술한 S345 단계에서 해당 해쉬값과 해쉬 데이터는 일치되는 것으로 확인될 것이며, 이 경우에는 이하에서의 2차 인증과정이 수행된다. However, if the above-described step S300 to step S345 is performed in one game execution device 100, the corresponding hash value and the hash data will be confirmed to be identical in step S345 described above, in which case 2 The second certification process is performed.

전술한 S345 단계에서 해당 해쉬값과 해쉬 데이터가 일치하는 것으로 확인되는 경우에, 게임실행 장치(100)는 전술한 S335 단계에서 획득된 현재시간과 다시 획득한 현재시간과의 시간차를 산출하며, 산출된 시간차가 1초 미만인지 여부를 판단한다(S355).When it is determined in step S345 that the corresponding hash value and the hash data match, the game execution apparatus 100 calculates a time difference between the current time obtained in step S335 and the current time obtained again, and calculates the result. It is determined whether the time difference is less than 1 second (S355).

산출된 시간차가 1초 미만인 경우에는 전술한 S330 단계에서의 실행 파일에 의해 해당 게임이 실행되며(S360), 게임이 실행된 후에는 전술한 S330 단계에서의 실행 파일은 삭제되도록 하는 것이 바람직하다(S365). If the calculated time difference is less than 1 second, the game is executed by the executable file in step S330 described above (S360), and after the game is executed, it is preferable to delete the executable file in step S330 described above ( S365).

만약, 전술한 S310 단계에서 생성된 실행 파일 및 전술한 S325 단계에서 생성된 암호화 데이터가 다른 사용자의 게임실행 장치(100)로 불법 복사된 경우라면, 불법 복사에 소요되는 시간을 고려할 때, 다른 사용자의 게임실행 장치(100)가 인식하고 있는 현재시간과 전술한 S335 단계에서 획득된 현재시간은 적어도 1초 이상의 차이가 있을 수 밖에 없을 것이다. 이와 같이 산출된 시간차가 1초 이상인 경우에는 해당 게임의 실행을 취소하게 된다(S350). If the executable file generated in the above-described step S310 and the encrypted data generated in the above-described step S325 are illegally copied to the game execution apparatus 100 of another user, when considering the time required for illegal copying, another user The current time recognized by the game execution device 100 of the present time and the current time obtained in the above-described step S335 will have a difference of at least one second or more. If the calculated time difference is 1 second or more, the execution of the game is canceled (S350).
