Efficient computer network information safety device

Abstract

The invention provides an efficient computer network information safety device, which comprises a first data transmission channel and a second data exchange channel, performs time-sharing unidirectional transmission with an open network through the first data transmission channel, and sends safety data to a target node computer in the open network through the second data exchange channel. Receiving feedback data from the target node computer through a second data exchange channel; the network information safety device executes a first operation to obtain open network data from the open network, and executes a second operation to send the feedback data to the open network; the first operation and the second operation are not executed at the same time. According to the technical scheme provided by the invention, the system safety of the node host in the open network when receiving the data is guaranteed, the feedback data is ensured to be used for the subsequent safety recognition process through various data processing processes, and the efficient computer network information safety guarantee is realized.

Description

technical field [0001] The invention belongs to the technical field of computer security, and in particular relates to an efficient computer network information security device. Background technique [0002] In recent years, with the continuous development of computer technology, computer networks have shown new features: the scale of the network has continued to expand, the number of network applications and network users has increased sharply, and the protocols carried by network equipment have continued to enrich. These new features of the network put forward higher requirements for the dynamics and flexibility of the network. In the traditional Internet architecture with TCP / IP as the core, network functions are often enclosed in network devices, and the delivery and deployment of its services are equivalent to the delivery and deployment of hardware devices. This closedness increases the difficulty of network optimization and limits the performance of customizing netwo...
