In information safety protector of the present invention, be respectively arranged with pad with the corresponding inboard of described protection wall on the inboard of described protection wall, the protection zone.
Implement information safety protector of the present invention, have following beneficial effect:
Information safety protector of the present invention comprises the protection wall that is provided with on fender and the described fender, and described fender and protection wall are assembled into a lid that can cover the protected area, and described protection wall is at least two circuit boards nested against one another.Cap structure of the present invention provides protection to element in the protection zone or parts, makes it not divulge a secret because of being subjected to physical attacks.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the STRUCTURE DECOMPOSITION synoptic diagram of information safety device first embodiment of the present invention;
Fig. 2 is the assembling synoptic diagram of information safety device first embodiment of the present invention.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only is used to explain the present invention.And be not used in qualification the present invention.
The information safety protector of the embodiment of the invention covers the zone that protected circuit board is provided with critical elements by circuit board and the protection wall that is provided with wiring; during sensitive data in rogue attacks wants to crack the zone; must break through protection wall on the information safety protector or fender earlier and be unlikely disconnects or short circuit the cabling that is provided with on it; otherwise can trigger control device and remove to wipe off sensitive data on the element, protect data security.
Extremely shown in Figure 2 as Fig. 1; in information safety device first embodiment of the present invention; information safety protector; comprise the protection wall that is provided with on fender and the described fender; described fender and protection wall are assembled into a lid that can cover the protected area, and described protection wall is at least two circuit boards nested against one another.
Wherein, the protection zone is the element 15 on the core circuit plate 19; element 15 can be that mainboard or other device on POS (pointsof sales) machine gone up the circuit that uses; element 15 also can be a multilayer circuit board; fender then is mesh plate 18 and mesh plate 20; the protection wall then comprises first circuit board and second circuit board; in embodiment; first circuit board, second circuit board are respectively external circuit plate 11 and interior circuit board 12. external circuit plates 11 and interior circuit board 12; interior circuit board 12 is set in the external circuit plate 11, and external circuit plate 11 and interior circuit board 12 are contour.
Be furnished with metal routing on external circuit plate 11 and the interior circuit board 12, these metal routings can disconnect or short circuit when being subjected to physical attacks, and disconnect or short circuit in trigger interlock circuit and remove to destroy or wipe off sensitive information on the element 15, make it not to be stolen.In order to increase protection, external circuit plate 11 and interior circuit board 12 are designed and manufactured as multilayer circuit board, and each layer of external circuit plate 11 and interior circuit board 12 staggers mutually.For the convenience of installing and protecting, external circuit plate 11 and interior circuit board 12 are all made the circuit board of annular hollow.
Information safety protector of the present invention also comprises conductive rubber 14, and described second circuit board 12 is provided with through hole, and described conductive rubber 14 is arranged in the described through hole.Conductive rubber 14 is a rectangular parallelepiped, and the end face of this rectangular parallelepiped, bottom surface are electrically connected with mesh plate 18, core circuit plate 19 respectively.Conductive rubber 14 not only makes protected core circuit plate 19 be electrically connected with mesh plate 18 as web member; also as the pressure condition of pressure sensitive device induction information safety feature; in case mesh plate 18 is opened conductive rubber 14 and will be triggered interlock circuit and remove to destroy or wipe off sensitive information on the element 15, makes it not to be stolen.Understandable, conductive rubber 14 can also be cylinder.
Be used for screw and the fastening fixed orifice of nut for mesh plate 18, mesh plate 20, protection wall and protected area being tightened together, on the core circuit plate 19 at mesh plate 18, mesh plate 20, place, protected area, being respectively arranged with.In this example, screw, nut are respectively Reference numeral 16,17.
