随着科学技术的高速发展,计算机网络的应用日益广泛。在我们不断享受这计算机所产生的便利时,我们也不得不面临着日益严峻计算机网络安全局面。个人网络信息常常被窃取、篡改、破坏等,为了保护网络信息安全,因此而产生了数据加密技术。本文将就网络安全和数据加密技术展开论述,并对数据加密技术在计算机网络安全中的应用探究。 With the rapid development of science and technology, the application of computer network is increasingly widespread. As we continue to enjoy the conveniences generated by this computer, we also have to face the increasingly serious situation of computer network security. Personal network information is often stolen, tampered with, destroyed, etc., in order to protect the network information security, resulting in data encryption technology. This article will discuss the network security and data encryption technology, and the data encryption technology in the computer network security application research.
