Data encryption transmission method

Abstract

The invention discloses a data encryption transmission method, relates to the technical field of data encryption, and solves the technical problem of low data encryption and transmission security caused by adopting a fixed key to encrypt and decrypt data in the prior art. The plaintext data is divided into a plurality of sub-data according to the set unit quantity, the plurality of sub-data are numbered, the number and the corresponding sub-data are reordered according to the natural sequence, the number sequence and the data sequence are obtained, the number sequence and the data sequence are encrypted through different secret keys, and the purpose of data encryption is achieved. The safety of the data is improved through double encryption; according to the method, before the numbers and the corresponding sub-data are reordered, the position feature tags corresponding to the numbers are obtained, the reference nodes are randomly selected, and the reference nodes can be quickly determined according to the number sequence; according to the invention, the data cracking difficulty is improved, and the data security is further ensured.

Description

technical field [0001] The invention belongs to the technical field of data encryption, in particular to a data encryption transmission method. Background technique [0002] As the types and quantities of data increase day by day, data storage encryption technology has also been applied more and more, and has become an effective method to protect data security. Data storage encryption technology usually refers to the use of specific technology to encrypt data before writing data to the device, so as to ensure the security of data on the storage device. [0003] In the prior art, an encryption and decryption unit is usually used to encrypt data. The encryption and decryption unit uses a fixed key to encrypt data, and uses a fixed key to decrypt stored data. The encryption and decryption unit usually uses a fixed and single key. There is a possibility of brute force cracking, and if the entire data is directly encrypted without processing, it will also increase the possibilit...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art; for this reason, the present invention proposes a data encryption transmission method, which is used to solve the problem that the prior art uses a fixed key to encrypt and decrypt data, resulting in data encryption and the technical problem of low transmission security, the present invention divides and numbers the data according to the division rules before encrypting the data, and then separately encrypts the data and the processed numbers, and then encrypts the encrypted data through a secure transmission channel transmitted to the target terminal
