Limited gibberish text one-way conversion method and encryption/decryption application thereof

Abstract

The invention discloses a limited gibberish text one-way conversion method and an encryption / decryption application thereof. The limited gibberish text one-way conversion method includes subjecting an initial gibberish text to one-way conversion with limited times and exclusive OR with message. The limited gibberish text one-way conversion method is actually an encryption / decryption method spending fewer bandwidths to accelerate the encryption / decryption speed. Compared with the traditional standard encryption / decryption method, the limited gibberish text one-way conversion method has the advantages that with fewer bandwidth spent, the encryption / decryption speed is improved by 10-100 times at the premise that the data safety is guaranteed; method is simple and widely applicable to large-scale data storage and transmission.

Description

technical field

[0001] The invention relates to data encryption, in particular to data encryption and decryption in large flow communication and large data storage encryption and decryption. Background technique

[0002] The purpose of communication encryption is to keep the secret of plaintext from being known by eavesdroppers. Corresponding to this is cryptanalysis, whose purpose is to recover the encrypted plaintext. According to the theory of modern applied cryptography, the existing encryption methods are generally divided into two categories: one is a symmetric encryption algorithm represented by DES and AES, and the other is an asymmetric encryption algorithm represented by RSA and ECC. Many encryption methods in communication rely on these two basic algorithms, or are optimized variants of these two algorithms, or rely on the principles of these two algorithms. But these two types of encryption methods all have a common defect: the speed is too slow. First of all,...
