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.

Claims

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.
