Description
Technical field
The present invention relates to financial machine and tool, especially relate to a kind of breaking-proof switch of financial machine and tool.
Background technology
The financial payment facility; Security situation like POS, ATM etc. is more and more severeer; More and more to the technological attack means of financial payment facility, like the financial transaction key that employing is uncapped, various methodologies such as cutting, chemical medicinal liquid burn into power analysis go to survey the facility stored.For this reason; The financial payment tissue has defined strict safety technique Valuation Standard, is called PCI (Payment Card Industry, payment card industry) safety certification standard; Have only the equipment that detects through Valuation Standard just to be considered to meet safety requirements, can resist current known attack means.
In the Valuation Standard, security module must be by close protection, and in the realization of protection security module, breaking-proof switch is a kind of the most frequently used method.Breaking-proof switch is meant that after facility were assembled completion, physical construction was pushed down switch, makes its closure, is not triggered.When illegally uncapping, physical construction lost efficacy, and switch breaks off, thereby triggered.
See also Fig. 5 and Fig. 6.Existing breaking-proof switch comprises circuit board 81 and conducting resinl 82.Wherein, circuit board 81 comprises inner ring 811, is located at the outer centre circle 812 of inner ring and is located at the outer outer ring 813 of centre circle.Inner ring, centre circle constitute one group of signaling switch.Inner ring, centre circle and outer ring are the pad of conduction.After the machine assembling was accomplished, conducting resinl 82 was pressed in the closure that realizes signaling switch on inner ring and the centre circle.When illegally being uncapped, conducting resinl breaks off and causes the signaling switch open circuit, thereby causes triggering.The outer ring is that anti-short circuit is attacked and designed.Common attack is to attempt to irritate conductive glue to make inner ring and centre circle circuit keep short circuit, realizes illegally uncapping and does not cause triggering thereby remove conducting resinl.The spacing of inner ring, centre circle and outer ring is very little, when conductive glue is injected, is easy to also flow on the outer ring, causes the Internal and external cycle short circuit, thereby triggers.
Occurred a kind of novel attack recently, started with, pierced mechanical compression leg with miniature electric drill from the mechanical compression leg of conducting resinl top; Bore and pass through conducting resinl, pour into non-conductive glue, conducting resinl is sticked on the pad; Glue itself is non-conductive, even be seeped on the outer ring, also can not trigger short circuit and attack.Like this when illegally uncapping, because breaking-proof switch causes and can't trigger by sticking dead.
Therefore, be necessary to develop a kind of new breaking-proof switch design, can avoid above-mentioned attack, do not reduce the security feature of original breaking-proof switch again.
Summary of the invention
The present invention provides a kind of breaking-proof switch and financial machine and tool in order to solve the prior art breaking-proof switch easily by the sticking technical matters that can't trigger of extremely causing.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts comprises circuit board and conducting resinl for a kind of breaking-proof switch of design, and said circuit board is provided with inner ring, around the centre circle of inner ring with around the outer ring of centre circle; Wherein, Said centre circle is separated and paired pad is formed by a plurality of, and said pad constitutes one group of signaling switch in twos, and said conducting resinl comprises the inner conducting layer that is pressed on the said inner ring, is pressed on the middle conductive layer on the said centre circle and is pressed on the outer conducting layer on the said outer ring; In said conductive layer be divided into a plurality of, and respectively one by one correspondence be pressed on respectively and organize on the signaling switch.
Said inner ring is square.
Said inner ring and outer ring ground connection.
Said conducting resinl comprises that one is connected the elastic arm between middle conductive layer and the outer conducting layer, and said middle conductive layer is located at the top of said outer conducting layer, the said middle said centre circle of conductive layer elastic compression.
Said centre circle is divided into 8 pads, and said middle conductive layer is divided into 4.
Said adjacent pad constitutes one group of signaling switch.
The present invention also provides a kind of financial machine and tool, and said financial machine and tool has above-mentioned breaking-proof switch.
Said financial machine and tool also comprises a casing, and said casing is pushed down said conducting resinl, and makes the said middle said centre circle of conductive layer elastic compression towards pressing down said elastic arm.
The present invention expands to the four edges of contact circuit through the circuit structure of circuit board with switching circuit, and is the relatively independent certain distance that leaves, and this is equivalent in original size, put into a plurality of breaking-proof switch, and conducting resinl also becomes with elongated bar pushes down pad.In little hole, inject glue, its perviousness is limited, desires to carry out the glue injection attacks, must bore identical many holes with signaling switch, and in the process of brill, can not shake too greatly, causes other switch triggering.And the dimensional requirement to the hole is littler, opens conducting resinl to prevent to bore, and causes opening circuit.All there is ground pad inner ring and outer ring at breaking-proof switch, prevent the short circuit attack.
