Abstract

The present application relates to a data encryption / decryption method, apparatus, computer equipment and storage medium. The data encryption method includes: acquiring plaintext data, key data, Fibonacci sequence, the first target Fibonacci number greater than the plaintext data in the Fibonacci sequence, and sequence information of the target Fibonacci number; Determine a random number based on the sequence information of the target Fibonacci number, use the random number as the selected sequence of the Fibonacci sequence, and obtain the Fibonacci number corresponding to the selected sequence; The base data is processed to obtain the corresponding Fibonacci conversion data; based on the plaintext data and the Fibonacci number corresponding to the selected sequence, the target plaintext data is determined, and the corresponding target plaintext data is obtained when the target plaintext data is equal to the preset value. Convert data in Fibonacci system to obtain Fibonacci system representation data corresponding to plaintext data; obtain ciphertext data based on Fibonacci system representation data and key data.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a data encryption method, device, computer equipment and storage medium, and a data decryption method, device, computer equipment and storage medium. Background technique [0002] With the development of Internet technology, people can browse and transmit various information through the Internet, which greatly facilitates people's life and work. In this process, data transmission security is involved, and it is of great significance to ensure the security of data transmission. [0003] Currently, when the data of the data sender is obtained, the data is generally encrypted, and then transmitted to the data receiver, and then the received data is decrypted. An eavesdropper can intercept the transmitted data, compare it with the real data distribution of a certain scene or based on existing knowledge through statistical analysis, and deduce the encrypted data. T...
