Abstract
A kind of support card carries the network safety isolator of solid-state disk, comprise outer net RJ45 interface circuit, network interface card RJ45 interface circuit, Intranet RJ45 interface circuit, signal switching module, mSATA modular converter, PCI-E packet switch (PS) module, mSATA interface circuit 0, mSATA interface circuit 1; Described signal switching module and mSATA modular converter and described PCI-E packet switch (PS) model calling, mSATA modular converter, mSATA interface circuit 0, mSATA interface circuit 1, outer net RJ45 interface circuit, network interface card RJ45 interface circuit, Intranet RJ45 interface circuit all with described signal switching model calling.The beneficial effects of the utility model are: the leakage effectively preventing Intranet information, only can connect hard disk with a mSATA data wire, data wire is not even needed all to use mSATA solid-state disk, insert PCI-E groove just can use, enormously simplify installation steps, switching between intranet and extranet two systems is quick, and outward appearance is also more succinct.
Description
Technical field
The present invention relates to information security field, especially a kind of support card carries the network safety isolator of solid-state disk.
Background technology
Along with the quickening of China's informatization paces, E-Government also development thereupon, government department and enterprises and institutions inside wait bulk information data to be also able to informationization, the existence of digitized form.While convenient work, bring great challenge also to the safe and secret work of government department and enterprises and institutions.In the Government and enterprise that some are higher to security requirement, do not allow the outer nets such as inner net computer connecting Internet, but some Intranets illegally connect and illegally access waits behavior still can cause great potential safety hazard outward.
Current nearly all government department has installed physical isolation card all, decreases the leakage of Intranet classified papers technically.But, use physical network Security Separate to mean and need connection two hard disks, Intranet system is separated physically completely with outer net system, need connection two power lines and two SATA data wires, just there is a possible mistake in this, user may misplug hard disk SATA data wire and cause divulging a secret of file.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of network safety isolator effectively preventing Intranet hard disk and outer net hard disk from mispluging, and guarantees that the hard disk information of Intranet can not be exposed online outside, prevents the leakage of information.
For solving the problems of the technologies described above, the invention provides the network safety isolator that a kind of support card carries solid-state disk, comprise outer net RJ45 interface circuit, network interface card RJ45 interface circuit, Intranet RJ45 interface circuit, signal switching module, mSATA modular converter, PCI-E packet switch (PS) module, mSATA interface circuit 0, mSATA interface circuit 1; Described signal switching module and mSATA modular converter and described PCI-E packet switch (PS) model calling, mSATA modular converter, mSATA interface circuit 0, mSATA interface circuit 1, outer net RJ45 interface circuit, network interface card RJ45 interface circuit, Intranet RJ45 interface circuit all with described signal switching model calling.
MSATA interface circuit 0 connects mSATA solid-state disk or hard disk as Intranet system, and mSATA interface circuit 1 connects mSATA solid-state disk or hard disk as outer net system, and PCI-E packet switch (PS) module is connected with the PCI-E groove on computer and carries out with it PCI-E and communicate.
Network interface card RJ45 interface circuit connects computer network interface card line, outer net RJ45 interface circuit and Intranet RJ45 interface circuit UNICOM's external the Internet and internal network respectively.Outer net RJ45 interface circuit can insert wireless network card, makes user to use wireless networking capabilities.
Beneficial effect of the present invention is: the leakage effectively preventing Intranet information, only can connect hard disk with a mSATA data wire, data wire is not even needed all to use mSATA solid-state disk, insert PCI-E groove just can use, enormously simplify installation steps, switching between intranet and extranet two systems is quick, and outward appearance is also more succinct.
