Game Data Transmission Security via Session Key and MD5 Digest
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Flash games lack reliable mechanisms to ensure the validity and accuracy of game data transmitted from client terminals to servers, making them vulnerable to tampering or counterfeiting.
Innovation Solution
A method and system where a client acquires a session key from a server, generates and sends a result digest using the MD5 algorithm for game data, which is verified by the server to ensure data integrity, preventing unauthorized access and tampering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing Flash games transmit game data unidirectionally from client to server without verification, then the system is simple and easy to operate, but the reliability of game data is poor and vulnerable to tampering
Solution Approach 1:
The server generates a session key in advance during login and sends it to the client before any game data transmission occurs. This preliminary action establishes a verification foundation that enables subsequent data integrity checks without adding complex mechanisms during actual gameplay.
Solution Approach 2:
The patent transforms the game data by generating a result digest through MD5 hashing combined with session key encryption. This parameter transformation converts raw game data into a verified format that can be authenticated by the server, ensuring data validity while maintaining transmission efficiency.
2Reliability
If the server verifies every game data packet with complex authentication, then data security is improved, but the transmission speed and productivity are reduced
Solution Approach 1:
Authentication preparation is performed in advance when the server generates and sends the session key during login. This one-time preliminary authentication eliminates the need for repeated complex verification processes during subsequent game data transmissions, maintaining both security and efficiency.
Solution Approach 2:
The patent replaces complex multi-step authentication mechanisms with a streamlined MD5 hashing and encryption process. This substitution maintains robust data verification while significantly reducing computational overhead and transmission time compared to traditional authentication protocols.
3Object-affected harmful factors
If no encryption is used for game data transmission, then the ease of operation is high and device complexity is low, but the security against counterfeiting and tampering is poor
Solution Approach 1:
The patent applies MD5 hashing and session key-based encryption to transform game data into a secured format. This parameter change adds cryptographic protection against tampering and counterfeiting while maintaining relatively simple implementation through standard cryptographic functions.
Solution Approach 2:
The session key acts as an intermediary element that enables secure data transmission without requiring complex end-to-end encryption systems. The session key mediates between the client and server, providing a straightforward yet effective security layer that resists tampering while keeping the overall system architecture simple.

AI summary
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.
