Abstract
The utility model relates to a kind of safety chip with Novel pin structure; comprise chip body; described chip body adopts quad flat pin QFN encapsulation; GND earth terminal is provided with in the middle part of this chip body; the all sides of this chip body are provided with several pins; the protection pin relating to key safety signal in described pin is arranged between earth terminal and all sides pin, and the lead-in wire of described all pins is all hidden below IC encapsulation.Described protection pin is the topology layout of single extension line or doubleleadout.Attack after this device makes assailant's physical entrapment node and steal and also become very difficult, thus considerably increase the security of E-Payment.
Description
Technical field
The utility model relates to a kind of safety chip with Novel pin structure.
Background technology
Along with the continuous progress of network technology and software engineering, based on the data safety mechanism that pure software realizes, the demand for security of E-Payment cannot be met.Therefore, be intended to now formulate based on the credible and secure standard based on secure hardware, widely use.Security mechanism based on hardware security chip development can effectively be protected electronic transaction data, prevent the access of disabled user.Meet the requirement to data and terminal security such as PCI.
Usually, what safety chip adopted is the pin package of the chip of various mode.The profile of the chip of its encapsulation is rectangle or square, and the surrounding of encapsulation has I/O pin to stretch out, and be connected to carry out circuit with circuit board, its pin, in chip exterior, easily by rogue attacks and detection, causes the safety problem of data.
Utility model content
The utility model makes improvement for above-mentioned prior art Problems existing, namely technical problem to be solved in the utility model is to provide a kind of safety chip with Novel pin structure, on basis to the hardware encipher of safety chip, further increase again the difficulty that assailant reads private information.
In order to solve the problems of the technologies described above; the technical solution of the utility model is: a kind of safety chip with Novel pin structure; comprise chip body; GND earth terminal is provided with in the middle part of this chip body; the all sides of this chip body are provided with several pins; the protection pin relating to key safety signal in described pin is arranged between earth terminal and all sides pin, and the lead-in wire of described all pins is all hidden below IC encapsulation.
Further, described chip body adopts quad flat pin QFN encapsulation.
Further, described pin number is 50, and the protection pin number of described key safety signal is two.
Further, described protection pin is the topology layout of single extension line or doubleleadout.
Further, be provided with the imaginary protection pin being used as fascination between the pin of described all sides, the arrangement of described imaginary protection pin is consistent with other pins.
Further, described imaginary protection pin is connected with warning circuit.
Further, described two protection pins are arranged on position corresponding to PIN9 and PIN19.
Compared with prior art, the utility model has following beneficial effect: on the basis to the hardware encipher of safety chip, further increases again the difficulty that assailant reads private information.To the protection pin package of safety signal be related to inner; by the mode that software and hardware, machinery and electronics combine; multiple safety approach makes secure data or sensitive data under the prerequisite retaining the security mechanisms such as traditional such as encryption, certification; make the attack after assailant's physical entrapment node and steal also to become very difficult, thus considerably increase the security of E-Payment.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Accompanying drawing explanation
Fig. 1 is the organigram of the utility model embodiment.
Fig. 2 is the organigram of the utility model embodiment one.
Fig. 3 is the organigram of the utility model embodiment two.
In figure: 1-chip body, 2-GND earth terminal, 3-pin, 4-protects pin, and 5-fabricates protection pin, the mono-leading-out wire structure layout of 6-, the topology layout of 7-doubleleadout.
Embodiment
Embodiment one: as shown in Figure 1 and 2; a kind of safety chip with Novel pin structure; comprise chip body 1; described chip body 1 adopts quad flat pin QFN to encapsulate; GND earth terminal 2 is provided with in the middle part of this chip body; this chip body 1 week side is provided with several pins 3, and the protection pin 4 relating to key safety signal in described pin 3 is arranged between earth terminal 2 and all sides pin 3, and the lead-in wire of described all pins is all hidden below IC encapsulation.Intermediate contact pads will inside contract, and the PIN of distance inside will have 0.6mm.
In the present embodiment, described pin number is 50, and protection pin 4 quantity of described key safety signal is two
In the present embodiment, described protection pin 4 is single leading-out wire structure layout 6, and described protection pin is PIN9 and PIN19.
In the present embodiment, be provided with the imaginary protection pin 5 being used as fascination between described all sides pin 3, no signal connects, and the arrangement of described imaginary protection pin is consistent with other pins.Outside be cannot see and is arranged on two inner PIN pins, stops the possibility of rogue attacks and detection.Can at imaginary protection pin 5, connect warning circuit, when this end points is by rogue attacks and detection, carry out the protection of being correlated with and alert process.
Embodiment two: as shown in Figure 3, its structure is roughly the same with embodiment one, and difference is that protection pin adopts doubleleadout topology layout 7.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
