Abstract

The invention relates to a sequence password generation method and device, computer equipment and a storage medium. The method comprises the following steps of: acquiring and initializing a key parameter, generating a random integer pair according to the key parameter, performing sequence encoding on the random integer pair by adopting a preset Fibonacci standard encoder to obtain a Fibonacci standard formula bit string, and performing logic OR operation bit by bit based on the Fibonacci standard formula bit string to generate a sequence password. The sequence password can be simply and quickly generated on the premise of meeting the Golomb randomness hypothesis, and the data security is higher. The data encryption method and device, the computer equipment, the storage medium, a data decryption method and device, computer equipment and a storage medium. According to the data encryption and decryption scheme, data encryption and decryption can be simpler and faster, and consumption of hardware resources and processing time is reduced.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a serial cipher generation method, device, computer equipment and storage medium, a data encryption method, device, computer equipment and storage medium, and a data decryption method, device, computer equipment and storage medium . Background technique [0002] Sequence cipher is also called stream cipher (Stream Cipher), which is a kind of symmetric cipher algorithm. Sequence cipher has the characteristics of simple implementation, easy hardware implementation, fast encryption and decryption processing speed, no or only limited error propagation, etc. Therefore, it maintains advantages in practical applications, especially in special or confidential institutions. [0003] There are two main symmetric encryption methods in modern cryptography, stream encryption and block encryption. Among them, stream encryption is to use an algorithm and a key to generat...
