Method for Authentication of Game Executing Authority Recording Medium for Storing Authentication Program of Game Executing Authority, and Server for Storing Authentication Program of Game Executing Authority

Abstract

Disclosed is a method for authentication of a game executing authority. The invention is implemented by steps of requesting a transmission of a decoding key for decoding a coded execution file for executing a game to an authentication server; decoding the coded execution file by the decoding key received from the authentication server to generate the execution file; hashing an obtained present time and a random data together to generate hashed data; encrypting the present time, the random data, and the hashed data by any fixing key to generate the coded data; transmitting the generated coded data as a parameter to the execution file; and confirming whether a hashed value obtained by hashing the present time and the random data, which are obtained by decoding the coded data by the fixing key, matches the hashed data.

1 . A method for authentication of a game executing authority comprising:
 (a) requesting a transmission of a decoding key for decoding a coded execution file for executing a game to an authentication server;   (b) decoding the coded execution file by the decoding key received from the authentication server to generate the coded execution file;   (c) hashing an obtained present time and a random data together to generate hashed data;   (d) encrypting the obtained present time, the random data, and the hashed data by any fixing key to generate a coded data;   (e) transmitting the coded data as a parameter to the coded execution file; and   (f) confirming whether a hashed value obtained by hashing the obtained present time and the random data, which are obtained by decoding the coded data by the fixing key, matches the hashed data.   
     
     
         2 . The method for authentication of a game executing authority according to  claim 1 , further comprising cancelling an execution of the game when the hashed value does not match the hashed data. 
     
     
         3 . The method for authentication of a game executing authority according to  claim 1 , further comprising calculating a time difference between the obtained present time and the obtained present time obtained again when the hashed value matches the hashed data. 
     
     
         4 . The method for authentication of a game executing authority according to  claim 3 , further comprising executing the game by the coded execution file when a calculated time difference is below 1 second. 
     
     
         5 . The method for authentication of a game executing authority according to  claim 3 , further comprising cancelling an execution of the game when a calculated time difference is 1 second or more. 
     
     
         6 . The method for authentication of a game executing authority according to  claim 4 , further comprising deleting the coded execution file when the game is executed by the coded execution file. 
     
     
         7 . A recording medium stored with a game executing authority authorization program that executes the respective steps in  claim 1 . 
     
     
         8 . A server stored with an authentication program of game executing authority that executes the respective steps in  claim 1 .
