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

摘要

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.
