Embodiment Construction

[0029] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] With the increasing types and quantities of data, in order to avoid the loss of sensitive data such as company data and customer data due to leakage, data storage encryption technology has been widely used 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 storage device, so as to ensure the security of the data stored on the storage device, correspondingly, when reading the sto...

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...
