TL;DR: In this paper, the encryption algorithm for encrypting the original data is determined from at least one preset encryption algorithm each time; wherein the encryption key for encryption is determined based on the determined algorithm type of the encryption algorithms, and therefore, the possibility that the encrypted data information transmitted at acertain time is cracked and then the transmitted encrypted information is cracked can be reduced, and the security during information transmission is greatly improved.

Abstract: The embodiment of the invention provides a data processing method and device and a medium. The method comprises the following steps: determining a target encryption algorithm from at least one presetencryption algorithm, determining an encryption key based on the algorithm type of the target encryption algorithm, encrypting original data based on the encryption key and the target encryption algorithm to obtain encrypted data information, and sending the encrypted data information to a second device. According to the embodiment of the invention, the encryption algorithm for encrypting the original data is determined from at least one preset encryption algorithm each time; wherein the encryption key for encryption is determined based on the determined algorithm type of the encryption algorithm; therefore, the possibility that the encryption algorithm and the encryption key for encryption each time are the same is low, the probability that the encrypted data information transmitted at acertain time is cracked and then the transmitted encrypted data information is cracked can be reduced, and the security during information transmission is greatly improved.
