The development of computer technology and the popularity of the network, resulting in more and more users over-dependent network. Most users rely on the network to obtain all the information they need, but also their own information and information stored in the network, so the user information and related information may be subject to theft, tampering, vandalism and other threats to ensure network security , To protect the integrity of data and information, and the application of data encryption technology in computer networks solves this problem. This article briefly introduces the principle of data encryption technology and the potential safety hazard of computer network. The application of data encryption technology in three aspects of network database, virtual private network and e-commerce operating system is analyzed and discussed.
