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
First Claim
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.

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.
