Abstract

The present invention provides a method for game data transmission, including: acquiring, by a client upon logging into a server, a session key assigned by the server; encrypting game data with the session key, and submitting the encrypted game data to the server; decrypting and verifying the received game data by the server, and saving the game data if the game data are proved to be valid. The present invention also provides a system, client apparatus, server and mobile terminal including the client apparatus to which the preceding method can apply. The method, system and apparatus of the present invention ensure that the client can transmit game data safely to the server and protect the game data from being tampered with or counterfeited.

Claims

1. A method for game data transmission, comprising:

acquiring, by a client upon logging into a server, a session key assigned by the server, and launching a game program;

encrypting game data by the client with the session key when the game data is to be submitted, and submitting the game data to the server.

2. The method according to claim 1, further comprising:

decrypting and verifying the received game data by the server, and saving the game data if the game data are proved to be valid.

3. The method according to claim 2, further comprising:

applying, by the client, feature conversion to the game data to be submitted to the server; and

applying, by the server, reversed feature conversion to the game data received by the server.

4. The method according to claim 1, before launching the game program, further comprising:

checking whether the session key assigned by the server is received, and launching the game program if the session key is received, otherwise preventing the game program from being launched.

5. The method according to claim 1, wherein the session key is generated based on the identity of the client and login time of the client by using a predetermined encryption algorithm.

6. The method according to claim 2, wherein

the encrypting comprises:

generating, by the client, a result digest based on the game data to be submitted, time of submitting the game data and the session key by using an MD5 algorithm, and sending the game data, the time of submitting the game data, the session key and the generated result digest to the server; and

the decrypting and verifying comprise;

generating another result digest by the server based on the received game data, the time of submitting the game data by the client and the session key by using the same MD5 algorithm used by the client, comparing the result digest generated by the server with the result digest from the client, and regarding the game data as valid if the two result digests are identical.

7. The method according to claim 6, further comprising:

when the result digest generated by the server is identical with the result digest from the client, comparing login time of the client with the current time on the server, checking whether the login time of the client is within a predetermined expiration limit, if yes, regarding the received game data as valid, otherwise regarding the received game data as invalid.

8. A system for game data transmission, comprising:

a server and a client in communication with the server, wherein

the client is adapted to acquire a session key assigned by the server upon logging into the server and encrypt game data with the session key before submitting the game data to the server; and

the server is adapted to assign the session key to the client based on the identity of the client, receive the encrypted game data from the client, decrypt and verify the received game data, and save the game data proved to be valid.

9. The system according to claim 8, wherein the client is further adapted to, before launching the game program, check whether the session key assigned by the server is received, and launch the game program if the session key is received, otherwise prevent the game program from being launched.

10. The system according to claim 8, wherein

the client is further adapted to apply feature conversion to the game data to be submitted to the server;

and

the server is further adapted to apply reversed feature conversion to the game data and then save the game data after proving the game data to be valid.

11. A client apparatus, comprising:

a first interface module, adapted to exchange data between the client and a server;

an authentication request module, adapted to log in the server via the first interface module and acquire a session key assigned by the server;

an application module, adapted to receive the session key from the server via the authentication request module, run an application, and submit encrypted game data to the server via the first interface module when the game data is required to be submitted; and

a data encryption module, adapted to encrypt the game data to be submitted by the application module with the session key and send the encrypted game data to the application module.

12. The client apparatus according to claim 11, further comprising:

a data conversion module, adapted to apply feature conversion to the game data to be submitted by the application module.

13. A mobile terminal, comprising:

a first interface module, adapted to exchange data between the client and a server;

an authentication request module, adapted to log into the server via the first interface module and acquire a session key assigned by the server;

an application module, adapted to receive the session key from the server via the authentication request module, run an application, and submit encrypted game data to the server via the first interface module when the game data is required to be submitted; and

a data encryption module, adapted to encrypt the game data to be submitted by the application module with the session key and send the encrypted game data to the application module.

14. The mobile terminal according to claim 13, further comprising:

a data conversion module, adapted to apply feature conversion to the game data to be submitted by the application module.

15. A server comprising:

a second interface module, adapted to exchange data between the server and a client;

an authentication confirmation module, adapted to assign a session key to the client via the second interface module;

a data decryption module, adapted to decrypt game data received via the second interface module and verify whether the game data are valid; and

a data storage module, adapted to save the game data proved to be valid by the data decryption module.

16. The server according to claim 15, wherein the data storage module is a system memory on the server or a storage space assigned to the client on the hard disk of the server.

17. The server according to claim 15, further comprising:

a data reversed conversion module, adapted to apply reversed feature conversion to the game data from the data decryption module to restore the game data.

18. Computer-readable medium embodying means for implementing a method for game data transmission, the method comprising:

acquiring, by a client upon logging into a server, a session key assigned by the server, and launching a game program;

encrypting game data by the client with the session key when the game data is to be submitted, and submitting the game data to the server.
