Abstract
The invention compresses and encrypts important resources of game client through randomly selecting compression way and encryption way in encryption process, and generates and upload indexing information to game server. In decryption process, the invention obtains indexing information from game server and select correct decryption way and decompression way to decrypt and decompress dispatched and encrypted important resources, further to complete dispatching of the above important resources to guarantee normal operation of game client. The encryption method improves the difficulty for the opposite side in malicious crack, effectively protects game client and important resources, maintains rights of original edition developer such as software copyright, contains infringement act of copycat mobile game developer, and hits crack and cheat of bad players to create a fair game environment.
Description
Technical field
The present invention relates to mobile phone games technical field, particularly relate to the encryption side of a kind of mobile phone games client valuable source
Method.
Background technology
Moving the development of Internet technology, intelligent mobile terminal is popularized rapidly, and mobile phone games quickly increase and become
The important segmentation field of field of play.Mobile phone games flourish and contain huge market potential behind, has expedited the emergence of big
Measure new mobile phone games listing.Develop and list the trip of a hands the most rapidly, become the problem of numerous size game developer.
Most game developer typically dashes off by working extra shifts or extra hours, optimize the modes such as project management accelerate mobile phone games develop into
Degree.But, the mountain vallage mobile phone games developer still having minority bad cracks popular mobile phone games client by illegal means, obtains
Take the resources such as the source code of its important script file etc., configuration documentation, picture, and exploitation mountain vallage mobile phone games accordingly.This
The rights such as the software copyright of master developer, or a kind of act of unfair competition have not only been encroached in behavior, will open master
The game of originator causes extreme shock so that substantial amounts of customer loss.
Additionally, also there is some mobile phone games player, crack mobile phone games client by illegal means, obtain its script literary composition
Part, configuration documentation etc., and develop plug-in accordingly or directly utilize game BUG, obtain illegitimate benefits in gaming, destroy game
Fairness.
Therefore, most of game developers can pass through encryption method, as much as possible protection game client and important
Resource.Certainly, different game developers, the method for its encryption, mode are different, but the most all show a trend, i.e. get over
Come the most complicated.The encryption method of a kind of mobile game as disclosed in CN104166810A, by program file and resource file
It is merged at least one big file and is encrypted, and the log file generated during by synthesizing big file extracts concrete program
File or resource file.
For the people of encryption, as long as increasing the other side as far as possible to crack the difficulty of (improper deciphering), it is simply that encryption
The effect pursued.The present invention will provide a kind of encryption method, combining encryption and compression means, and and server the most mutually
Dynamic, improve and crack difficulty.
Summary of the invention
In order to solve the problems referred to above, to realize more efficient cipher round results, the present invention provides a kind of mobile phone games client
The encryption method of end valuable source, its ciphering process is, the compression unit from developing instrument randomly selects a kind of compress mode,
Ciphering unit from developing instrument randomly selects a kind of cipher mode, and the valuable source needing encryption is compressed, is encrypted,
Generate index information according to described compress mode, cipher mode, and above-mentioned index information is uploaded to game server simultaneously；Its
Decrypting process is, obtains above-mentioned index information from game server, is arranged at the decryption unit of described client bottom, decompression list
Unit chooses correct manner of decryption according to described index information, invoked valuable source of having encrypted is solved by decompression mode
Close, decompression；Than prior art, by above-mentioned encryption method (including ciphering process and matched decrypting process), it is possible to
Improve the difficulty that the other side's malice cracks, effectively protection game client and valuable source thereof to a certain extent.
The embodiment of the present invention provides the encryption method of a kind of mobile phone games client valuable source, and the method includes:
In mobile phone games client development process,
From for the substantial amounts of resource generating mobile phone games client of packing, choose the client resource being necessary encryption
