Method for dynamically encrypting network data, and storage medium

Abstract

The invention discloses a method for dynamically encrypting network data, and a storage medium. The method comprises the following steps: adding additional information at a specified location of a byte stream of a pre-encrypted message, wherein the additional information comprises random encryption algorithm representation bit, and a random key corresponding to an encryption algorithm representedby the random encryption algorithm representation bit; and performing encryption processing on the message content section of the pre-encrypted message by adopting the encryption algorithm representedby the random encryption algorithm representation bit in the additional information and the random key corresponding to the encryption algorithm represented by the random encryption algorithm representation bit. Through the method for dynamically encrypting network data and the storage medium disclosed by the invention, the data in the network transmission can be dynamically encrypted, so that the same plaintext data is corresponding to different ciphertext data, thereby directly and effectively a behavior that a WPE type software counterfeiting sender sends the data capable of being processed by a receiver to the receiver.

Description

technical field [0001] The invention relates to the technical field of data encryption, in particular to a method for dynamically encrypting network data and a storage medium. Background technique [0002] The existing data encryption method in network transmission is to use an encryption algorithm and an encryption key to encrypt the target data, and after the data receiver receives the encrypted data, the encryption algorithm and the encryption key are used to decrypt the data , so as to achieve the purpose of transmitting network data. The characteristic of this method is that if it is the same plaintext data, there will be the same ciphertext data. [0003] Based on this, WPE-type software can determine the function of a certain piece of ciphertext data transmitted in the network, thereby forging the sender of network data to send a large amount of certain piece of ciphertext data to the receiver of network data, in order to Deceiving the server also causes the network ...

[0003] Based on this, WPE-type software can determine the function of a certain piece of ciphertext data transmitted in the network, thereby forging the sender of network data to send a large amount of certain piece of ciphertext data to the receiver of network data, in order to Deceiving the server also makes the network data receiver process the received data and consume unnecessary resources

For example, software that simulates legitimate players in existing online games communicates data with games operated by game developers to achieve the purpose of obtaining virtual property in games without manually operating the characters in the game, and in During this process, the game server always believes that this behavior comes from a real player operation, so for other players, this behavior destroys the fairness in the game
