One-computer double-network physical isolation computer with multi-channel switching circuit

Abstract

The invention belongs to the technical field of computers, and relates to a one-computer double-network physical isolation computer, in particular to a double-host satellite positioning security computer with a multi-channel switching circuit. The computer comprises a master control system, hosts, a power source and a machine case, wherein the master control system comprises an intelligent master control unit and a switching unit. The two hosts include the host 1 and the host 2 respectively, physical shielding isolation is achieved between the two hosts, connectors of a keyword and a mouse of the host 1 and connectors of a keyboard and a mouse of the host 2 are respectively connected to the multi-channel switching unit of the intelligent master control system, and the double hosts are switched for use through the intelligent master control system. The computer can be used for integrated desk computer industrial production, has the triple illegal starting preventing function, the one-way information conversion function, the outage preventing active protection function, the active or passive self-destruction function and the like, has good application prospects in the technical field of computers, and makes contributions to departments such as party and government organizations, army, national defense, scientific research institutions and enterprises.

Description

technical field [0001] The invention belongs to the technical field of computers, and relates to a safe and confidential computer, in particular to a physically isolated computer with one computer and two networks. The invention can be used not only in the industrialized production of integrated desktop computers, but also in the industrialized production of all-in-one computers and notebooks. Background technique [0002] With the rapid development of the Internet, computer network leaks are becoming more and more serious, and the problem of confidential data loss in confidential computers has become a very headache for party and government agencies, military, national defense, scientific research institutions and public service organizations that collect basic information of citizens. . According to relevant data, in the current secrecy work, leaks caused by computer networks and computer data loss have accounted for more than 70% of the total number of leaks, and are sho...

Problems solved by technology

Although this method can effectively prevent users from unintentionally leaking secrets, it is inconvenient to use and operate, and there are many connections between the hosts of the equipment. The wrong connection problem, the confidentiality performance is relatively weak

The other is to set up two mainboards separated by an isolation card in one computer, which are connected to the internal network and the external network respectively. When one mainboard is working, the other mainboard will be closed, which makes the actual operation both cumbersome and inconvenient.

Existing security and confidentiality computers still rely on normal operation to perform the confidentiality function. If a thief disassembles the computer and connects the secret-related hard disk to another computer for decryption after the power is cut off, it will still lead to leakage.

Therefore, the security and confidentiality function of the existing integrated security computer is obviously not perfect, and there are still significant defects in the use efficiency.
