Embodiment Construction

[0019] The present invention establishes a virtual isolation channel through the public network between different geographic locations, and high-intensity encryption is performed on communication data, so that any third party cannot effectively decrypt the encrypted data and cannot tamper with the communication data.

[0020] Such as figure 1 As shown, the device that establishes a network isolation channel builds a secure communication tunnel between two or more network devices through a network channel isolation device (Tunnel Isolating Device, TID for short). Network channel isolation devices such as figure 1 As shown, there is an inner network interface 11, an outer network interface 21, a network processor 31 (for data packet encryption and decryption processing and other transaction processing), an initialization key 22, a group of LED indicator lights 32 (for indicating the device status), a power connector 33 and an optional USB connector 12 (which can be used to init...

Abstract

The invention relates to a device for establishing a network isolated channel and a method thereof. A safe communication channel is established between two or multiple network devices through a network channel isolating device. The network channel isolating device is provided with an internal network interface and an external network interface. The internal network interface is connected with an internal network device. The external network interface is connected with an external network device. The network device which is connected with the internal network interface is protected by the network channel isolating device. A set of network devices protected by the network channel isolating device is called as a network channel isolating device protection domain. Host computers in different domains can communicate safely. By establishing a virtual network isolated channel through a public network among different geographic locations and by adopting an encryption algorithm recommended by the State Secrecy Bureau to conduct high-strength encryption to communication data, any third party cannot effectively decrypt the encrypted data and the communication data cannot be falsified; and the problem that different departments of small and medium enterprises cannot communicate safely through the public network is solved.

Description

technical field [0001] The invention relates to a device and a method for establishing a network isolation channel, belonging to the technical field of network communication security. Background technique [0002] With the popularization of the network and the promotion of the national Internet of Things strategic plan, the security of network communication has aroused strong concern from the whole society. Lawbreakers use network tools to commit high-tech crimes, and terrorists and hostile forces use network tools to carry out sabotage activities. Facing the severe situation of information security, there are many weak links in our country's network security system in terms of prediction, response, prevention and recovery capabilities. According to the assessment of the information protection capabilities of various countries by the British "Jane's Strategy Report" and other network organizations, my country is listed as one of the countries with the lowest protection cap...
