Description
Technical field
The present invention relates to electromangnetic spectrum field, particularly relate to a kind of electromagnetic shielding mouse.
Background technology
Mouse is as a kind of data, the processing equipment of information, it has also become the indispensable ingredient of computer.Mouse and
Information between main frame is carried out with electromagnetic wave for carrier alternately, and common mouse does not does shielding processing, these electromagnetism
Ripple can either intentionally or unintentionally radiate to surrounding space.
Owing to ELECTROMAGNETIC RADIATION SIGNATURE carries the information processed in computer, it is easily caused the generation of the leakage of a state or party secret, therefore, for
Realize information security as far as possible, it is necessary to the electromagnetic leakage of mouse protected.
Mouse anti-interference, Low emissivity can be referred to as TEMPEST mouse.Now, the TEMPEST technology of mouse mainly uses
Following technical measures:
1, filtering technique
Filtering is a highly important technology in TEMPEST, and filtering can effectively reduce and suppress electromagnetism spoke
Penetrate.But, the insertion loss of wave filter, internal driving, signal handling capacity, tunable need to be thought over when using wave filter
The various factors such as the ability of property, distorted signals, cost and suppression garbage signal.
2, wiring is combined with components and parts
Components' placement and the line arrangement of printed circuit board are the most critically important, should take the quarantine measures of necessity, make to be loaded with
Not the wire of homology electric current away from, to reduce the harmful coupling between each wire.To this end, the cabling on wiring board should be reduced as far as possible
Length with component down-lead.Generally use multilayer wiring and surface mounting technique, and select large scale integrated circuit, to reduce
The radiation of circuit.The mouse circuit plate that design internal wiring is more complicated, when arranging cabling, cabling to be avoided occurs drastically to become
Change, use balance wiring method as far as possible, and each layer signal cabling arranges ground plane, to reduce the generation of interference signal.
3, red/black isolation
" red ", refers to carry the information of sensitivity, and electromagnetic protection has the strictest restriction to the protection of red signal；
" black ", then it represents that do not carry sensitive information, electromagnetic protection is the loosest to the protection of black signal.By red and black isolation in mouse
Open, be to prevent the sensitive information entrained by red signal from passing to black signal by the way of wired or wireless, thus cause
The leakage of sensitive information.
4, disturbed sources of noise is utilized
This technology mainly utilizes two ways to reduce the probability of electromagnetic information leakage.A kind of mode is to produce one
The interference unit of raw noise is placed on the equipment sides such as mouse, together with the electromagnetic information radiation that the noise that interference unit produces produces with equipment
Leaking out, the useful information leakage making computer equipment produce is difficult to be received reduction；Two is will to process setting of important information
Standby being placed on centre, its surrounding puts some equipment processing general informations, allows the leakage of information outside spoke together that these equipment produces
Penetrate, thus realize important information and be difficult to be received the target of reduction.
5, shield technology is used
Shielding is basic measures in TEMPEST technology.Its purpose, one is to limit inside to radiate to surrounding space
Electromagnetic information；Two is to prevent inside the Radio frequency interference access arrangement in surrounding space.TEMPEST technology to shielding requirements very,
General requirement is done from printed circuit board.And the key shielded essentially consists in the physical characteristic of shielding material, particularly metal pair
The impact of shield effectiveness is the biggest.In general, the shield shell structure of equipment is many to be designed with metal, and the screen layer of cable many with
The metal gauze of high conductivity is constituted.When cable shield needs to realize electric field shielding and magnetic field shielding simultaneously, typically use
The combined material of high conductivity and high permeability is as the screen layer of cable.
Owing to the electric pulse in computer can pass on mouse pad by mouse cable, due to this electric pulse spectral range very
Wide (it has been generally acknowledged that frequency range is from 150kHz to 10GHz).Above several ways is in frequency range 150kHz to 10GHz scope
In, the electromagnet shield effect of the electromagnetic signal that mouse is incoming to other equipment the most simply can reach about 60dBuV/m.Its performance
The information equipment to electromagnetic leakage requirement is strict can not be reached far away use.
Accordingly, it would be desirable to develop a kind of electromagnetic shielding Mus for electromagnetic shielding equipment that can solve the problem that above-mentioned technical problem
