Abstract

The invention relates to an information security communication method and system, a network card and a storage medium. The network card is arranged at a data sending end. Communication configuration parameters sent by the data sending end are received; according to the communication configuration parameters, an encryption public key is obtained; according to the encryption public key, an asymmetric algorithm is adopted for performing network layer framework-based multi-layer encryption on transmission data output by the data sending end to obtain encrypted data; and the encrypted data is pushed to a data receiving end for setting the communication configuration parameters. In the whole encryption process, encryption is applied to the network card; when the network card is started, according to the obtained public key, the transmission data in the network card is encrypted layer by layer by adopting the asymmetric encryption algorithm; the transmission data of each layer is subjected toencryption protection, so that the operation speed of a computer is not influenced; and multi-layer encryption is carried out on the transmission data, so that the data transmission security is guaranteed conveniently and comprehensively.

Description

technical field [0001] The present application relates to the technical field of communication security, in particular to an information security communication method, system, network card and storage medium. Background technique [0002] With the rapid development of information communication such as big data, the Internet, and cloud computing, network security issues are also emerging one after another. Computer network security is getting more and more attention. "There is no national security without network security." Data security issues have gradually developed into national security issues. core link. [0003] Most of the existing technologies use IP layer encryption technology to encrypt network data. Since the IP layer encryption method encrypts network data at the IP layer, although the security of information communication is guaranteed to a certain extent, this encryption method occupies a large number of Running the memory slows down the speed of the computer,...
