Encryption method for network security

Abstract

The invention provides a network security encryption method, and relates to the technical field of network security. The method comprises the following steps: S1, region division: dividing a network according to different attributes and effects, and encrypting a single region, and S2, network boundary protection: performing security protection on boundaries among the divided and encrypted networks to prevent the influence of network concatenation. According to the method, large environment of the whole network is regionally divided into different small environments, the boundary of each small environment is protected, on one hand, the encryption degree can be improved, on the other hand, encryption access can be finely divided, encryption is carried out according to different levels, and the encryption is more meticulous; and through RSA and SM encryption, it can be ensured that the internal key is safer and is not prone to being cracked and infected by common programs. Therefore, it can be guaranteed that the secret key is in a relatively safe environment state in the transmission process, and after the secret key is received, the secret key is cracked and compared through corresponding hardware and software so that the safety of the file can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to an encryption method for network security. Background technique [0002] Network security means that the hardware and software of the network system and the data in the system are protected from being damaged, changed, or leaked due to accidental or malicious reasons, the system runs continuously and reliably, and the network service is not interrupted. And the system must have the ability to protect the security of sensitive information to ensure the reliability and confidentiality of the system and network. A common method to protect sensitive information is encryption. There are many types of cryptographic algorithms that can be used in various occasions. [0003] There are still problems in the existing technology to solve network security. There are different encryption security algorithms among various company departments, which were integrated in their respective ...

Problems solved by technology

[0003] There are still problems in the existing technology to solve network security. There are different encryption security algorithms among various company departments, which were integrated in their respective software modules before, and there is a large degree of repeated development and quality differences. The degree of coupling of application software is very high, and the degree of security is uneven. There are some disadvantages of different degrees in the existing commonly used encrypted transmission methods. Also known as "network gatekeeper" and "physical isolation gatekeeper", it is used to realize the security isolation between networks of different security levels and provide moderately controllable data exchange software and hardware systems, but the security isolation gatekeeper is expensive and difficult to deploy.
