[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the anti-protective device STRUCTURE DECOMPOSITION synoptic diagram of stealing of the utility model sensitive data.
Fig. 2 is the another kind of structural representation of the utility model gusset plate.
[embodiment]
See also shown in Figure 1; the anti-protective device of stealing 10 of sensitive data of the present utility model; comprise a top board 1, a base plate 2 and a gusset plate 3; the three is pcb board (being printed circuit board (PCB)); wherein top board 1 or base plate 2 have at least one to relate to sensitive data circuit 20; this sensitive data circuit 20 can be located at the upper surface of described base plate 2, or is located at the lower surface of top board 1, and perhaps both all have.Described top board 1, base plate 2 and gusset plate 3 interconnect the place of safety 4 that sensitive data circuit 20 is surrounded a sealing.In case the sensitive data of attempting to steal or destroy in the sensitive data circuit 20 is arranged, must first attack protection device 10, destroy or wipe sensitive data thereby impel protective device 10 to cause that interlock circuit triggers, guarantee the safety of sensitive data.Wherein top board 1 major responsibility is the physical attacks of protection from the top, and base plate 2 major responsibilitys are protection physical attacks from the below, and gusset plate 3 major responsibilitys are protection physical attacks from the side.
And the inside of described top board 1, base plate 2 and gusset plate 3 is equipped with two-way protection cabling 5, the whole place of safety 4 of comprehensive covering.This two-way protection cabling 5 adopts parallel cabling, and two paths of signals to walk distance between centers of tracks minimum, form closed loop, winding mode is labyrinth shape, covers whole place of safety, forms the minimum wire netting of spacing, non-blind area.Wherein, be provided with a main control chip (not shown) in the described base plate 2, this main control chip is by the guard signal of described two-way protection cabling 5 output two-way pulse waveforms.This guard signal is imported described main control chip again by way of top board 1, base plate 2 and gusset plate 3, detects in order to closed loop.In addition, when top board 1 related to sensitive data circuit 20, this main control chip just was located in the top board 1, to obtain same effect.
Be the attack of protection wherein from the top because of top board 1 major responsibility, base plate 2 major responsibilitys are protection attacks from the below, the cabling of the protection cabling 5 of the two inside need distribute one deck at least, as the protection routing layer, the adjacent traces layer need be set to bus plane or stratum, increases the difficulty of vertical assault; Gusset plate 3 major responsibilitys are protection attacks from the side, and its protection cabling 5 numbers need distribute two-layer at least, specifically decide according to its thickness, and thickness is big more, and the then required number of plies is many more, to reduce the gap between each layer.In principle, the number of plies of the protection cabling 5 of pcb board is many more, and extraneous breakthrough difficulty is big more, and the internal layer of protecting cabling 5 to need at pcb board, can not be on the top layer.Connects between the routing layer in the same pcb board and is undertaken, and protect the signal leading point (can be pad or contact) of cabling 5 though be positioned at the surface of pcb board by inner buried via hole, must be in the place of safety 4 inside, can not expose.
Described gusset plate 3 is provided with the fluting 31 more than 4, and conduction zebra bar 6 is placed in the inside of each fluting 31, and protection cabling 5 links of described top board 1 and base plate 2 are equipped with the golden finger pad, and this link carries out physical connection by conduction zebra bar 6.And the cabling of described gusset plate 3 and base plate 2 is connected by solder joint, and this bond pad locations is located at the medial surface of conduction zebra bar 6 and is in the place of safety 4, like this, the obstruct of conduction zebra bar 6 has been arranged, and solder joint more is difficult to be detected by the external world.Described top board 1, base plate 2 and gusset plate 3 threes are equipped with screw hole 32 near conduction zebra bar 6 positions, pass screw hole 32 by screw 7 three is fixed, and make conduction zebra bar 6 internal signals and described protection cabling 5 conductings.If screw 7 is attempted to unclamp by the external world, open top board 1 or base plate 2, the zebra bar 6 that then conducts electricity unclamps, thus tripping protection cabling 5 paths trigger the sensitive data erase mechanism.
The cross sectional shape of described gusset plate 3 can be decided according to the actual regional extent that relates to sensitive data circuit 20; be generally polygon; as can be a rectangle (as shown in Figure 1); it perhaps is a rectangle and a combination (as shown in Figure 2) of the rectangle of opening on one side; the latter is applicable to that the part needs the situation of opening; IC-card card inserting mouth of POS equipment etc. for example; then can increase the rectangular slab of openings at one side; with two plates as one; to form two places of safety 4, can protect the sensitive data in the plug-in card district so simultaneously.Moreover, bigger as the height of protected data circuit, can pile up by the polylith pcb board and form, but the signal leading point that need follow the protection cabling equally is the principle that connection pads does not expose.
Surround a safe space by the anti-protective device of stealing of sensitive data of the present utility model, the circuit of subsidiary sensitive data be placed in one, extraneous as will steal sensitive data, need break through the protection cabling that covers the place of safety earlier, and if any one road cabling disconnects; Or two-way cabling short circuit; Or any one road cabling is with the earth signal short circuit; Or any one road cabling is with the power supply signal short circuit; To cause that all closed loop detects failure, main control chip promptly can determine outside world, wipes sensitive data immediately, and the external world just can't steal like this.
