The Application Analysis of Computer Network Security Data Encryption Technology

In the information age, the development and application of big data technology has provided great conveniences to people’s production and life, but at the same time, it has also deteriorated the safe operating environment of computer networks, and has brought greater threats to user privacy, property and data security. The research on computer network security under big data combines the current data encryption, analysis of reasons affecting computer security, and the effective use of data encryption for computer security as the main basis. From the introduction of data encryption technology, data encryption in computer security analysis and research on effective value, destruction of data by illegal means, destruction of data by virus intrusion, determination of data encryption direction, the research on encryption technology and the application of digital encryption technology, its purpose is to strengthen the operation of data encryption technology, in order to improve the computer security, providing reference materials for related research.
