Problems solved by technology
[0002] In the current online game client, the data may be intercepted during the running process, and the game data may be illegally tampered with. Even if the data sent by the client and the data stored in the server are used for verification, flammable cannot avoid the memory of the game client. Situations where data during normal operation has been tampered with

Embodiment approach
[0065] An implementation method for encrypting game data in memory, the method includes the following two aspects:
[0066] like figure 1 As mentioned, in the first aspect, the storage method of game data is as follows:
[0067] 1. Obtain the current value of the game data from the first memory address;
[0068] 2. Same as the method of memory encryption above, encrypt the current value to obtain the ciphertext;
[0069] 3. Store the encrypted ciphertext from the second memory address.
[0070] Through the above steps, the value actually stored in the memory of the game data is the ciphertext of the second memory address. In this embodiment, the principle of using a memory scanning tool (for example: Jinshan Ranger, Bamen Artifact) to locate the memory address of the message data is as follows :
[0071] The first step is to scan the value of the variable that needs to be modified (for example, the combat power value of a certain character is 100 at this time), and obtain ...

The invention relates to the technical field of computers, and discloses a memory encryption method for game data, all game data are encrypted and stored in a memory, real-time data cannot be obtained through a memory scanning tool, and the method comprises the following steps: S1, converting a user key lambda into a digital expression mode through a character code table, wherein lambda is used for encrypting plaintext data; according to the encryption process, a random key is randomly selected at first, then the random key is used for carrying out position replacement on plaintext data, then a user key is called to encrypt the random key and the plaintext data, encryption is a process of encrypting various information layer by layer, and decryption is contrary; firstly, the calculation amount and N are in a linear relation, namely, O (N) = axN, O (N) is the calculation amount of a data block, a is a constant, so that the encryption strength is linearly related to the file size, and the technical scheme has the beneficial efficiency advantage when a large amount of data is encrypted and decrypted in a memory.
Description
technical field [0001] The invention relates to the field of computer technology, in particular to a game data memory encryption method, system, device and storage medium. Background technique [0002] In the current online game client, the data may be intercepted during the running process, and the game data may be illegally tampered with. Even if the data sent by the client and the data stored in the server are used for verification, flammable cannot avoid the memory of the game client. A situation in which data during normal operation has been tampered with. [0003] This is because the memory is an important device in the computer to communicate with the central processing unit. All programs in the computer run in the memory. The function of the memory is to temporarily store the calculation data in the CPU and exchange data with the external memory of the hard disk light. Data, as long as the computer is running, the CPU will transfer the data that needs to be calculat...
