Data encryption method and device and computing equipment

Abstract

The invention discloses a data encryption method and device and computing equipment. The data encryption method comprises the following steps: acquiring to-be-encrypted data; for each bit in the data, converting the initial form representation of the bit into binary representation, then carrying out cyclic shift for a plurality of times, and converting the shifted binary data into the initial form representation of the data to obtain shifted data; carrying out Fibonacci coding on the shift data to obtain Fibonacci coded data; encoding the carrier image to obtain image encoding data, and selecting a part of data from the image encoding data as a secret key; encrypting the Fibonacci coded data by using the key to obtain encrypted data, and writing the encrypted data into the carrier image data to obtain encrypted image data; and storing the encrypted image data in a cache. The invention also discloses a corresponding device and computing equipment.

Description

technical field [0001] The invention relates to the technical field of data encryption, in particular to a data encryption method, device and computing equipment. Background technique [0002] Since the birth of the first computer, after decades of rapid development, information technology has entered every aspect of our lives, constantly changing our lives. We have entered the information age. The information age is an era of information explosion. It is difficult to store and transmit a large amount of information effectively by traditional methods. Therefore, the development of information technology based on computer technology and network technology is particularly important. . As one of the main means of protecting information security, cryptographic technology can not only ensure the confidentiality of information, but also ensure the integrity and authenticity of information, and prevent information from being tampered with, forged and faked. With the development a...

Problems solved by technology

[0004] The encryption effects of the above two network security transmission technologies are average, and there are still risks of being sniffed, intercepted, cracked, simulated, and infiltrated

In addition, these two network security transmission technologies only focus on the data itself, while ignoring the data transmission method. Most of the data transmission methods use plaintext transmission. While plaintext transmission causes great network security risks, it also makes the fixed binary The encoded form becomes less secure

[0005] To sum up, both of the above two existing network security transmission technologies have the problem of unsatisfactory encryption effect and potential safety hazards in the data transmission process.
