Description

Handheld device physical security protective device

[technical field]

The utility model relates to domain of communication equipment, particularly a kind of handheld device physical security protective device.

[background technology]

Develop rapidly along with electronics industry and computer technology, be deep into every field, no exception such as the POS product of financial industry and personal mobile phone etc., tend to store the data message of some hypersensitivities in the electronic circuit of hand-hold communication appliance, such as password and private key etc., but thereupon produced the safety problem of data message, such as the problem that is stolen of sensitive data, more and more cause people's great attention.Some handheld devices are the products that utilize the veneer circuit to realize, the shell of its this kind equipment locks by the mode that upper and lower cover fastens.This and wes' conventional P OS product structure is not quite similar, owing to there not being the securing member such as screw, this structure is taken off circuit and brought certain difficulty realizing that safety is anti-.Therefore, how effectively to guarantee the anti-problem of taking off circuit of safety, become one of important topic of people in the industry's exploratory development.Various forms of protective devices and method also occur immediately, and wherein, method commonly used is to prevent by software, though the behavior that has effectively stoped a part to steal sensitive information can't be played any protective action to the attack of physics and electronics aspect.

[summary of the invention]

The technical problems to be solved in the utility model is to provide a kind of handheld device physical security protective device, and this device has not only been protected keyboard, the sensitive data circuit of equipment, has prevented effectively that also the pressure of equipment from opening.

The utility model is achieved in that a kind of handheld device physical security protective device, comprising:

One PCB wiring board, its surperficial the first half are provided with safe processor and have at least one to relate to the sensitive data circuit, and its surperficial the latter half is provided with a plurality of button golden fingers, and described PCB wiring board two ends are respectively arranged with the anti-pass of opening of a conduction carbon granules;

At least 4 safe DOME contacts, it is arranged on the PCB wiring board and between described a plurality of button golden fingers;

One security mask protection assembly, it comprises with the safe fence of zebra bar and safeguard protection cover plate; Described safe fence is located at described safe processor and has at least one to relate on the sensitive data circuit, and described safeguard protection cover plate is located on the described safe fence, and described safety cover intralamellar part is equipped with the protection cabling.

Further, described protection cabling adopts parallel cabling, the driving closed loop, and winding mode is labyrinth shape.

Further, described safe fence thickness is 1～1.5mm.

Further, described safeguard protection cover sheet thickness is 0.8～1.2mm.

The utility model has the advantage of: the utility model comprises a PCB wiring board, it is provided with safe processor and has at least one to relate to the sensitive data circuit, also be provided with a plurality of button golden fingers, described PCB wiring board two ends are respectively arranged with the anti-pass of opening of a conduction carbon granules; Also comprise at least 4 safe DOME contacts, it is arranged on the PCB wiring board and between described a plurality of button golden fingers; One security mask protection assembly, it comprises with the safe fence of zebra bar and safeguard protection cover plate; The novel safe processor of this usefulness can provide state-detection, the preservation sensitive data of safe physical mechanism mesh (grid) and switch (switch), also realizes simultaneously safe physical mechanisms such as UVL (Virus Name) attack, environment temperature detection, overvoltage detection; The anti-pass of opening of the conduction carbon granules at its PCB wiring board two ends; can prevent effectively that shell is forced to open; its 4 safe DOME contacts have the anti-defencive function of taking off; effectively protect the sensitive data of digital block button, its security mask protection assembly has effectively been protected safe processor and has been related to the sensitive data circuit.The handheld device that this physical security protective device is realized for the veneer circuit has played good physical security protection.This device has not only been protected keyboard, the sensitive data circuit of equipment, has prevented effectively that also the pressure of equipment from opening.

[embodiment]

See also Fig. 1 to shown in Figure 3, a kind of handheld device physical security protective device of the present utility model comprises:

One PCB wiring board 1, its surperficial the first half is provided with safe processor and has at least one to relate to sensitive data circuit 11, its surperficial the latter half is provided with a plurality of button golden fingers 12, and described PCB wiring board 1 two ends are respectively arranged with anti-the opening of a conduction carbon granules and close 13;

At least 4 safe DOME contacts 14 (as shown in Figure 2), it is arranged on the PCB wiring board 1 and between described a plurality of button golden fingers 12;

One security mask protection assembly 2, it comprises safe fence 22 (as shown in Figure 3) and safeguard protection cover plate 23 with zebra bar 21; Its safe fence thickness is 1～1.5mm, and its safeguard protection cover sheet thickness is 0.8～1.2mm; Described safe fence 22 is located at described safe processor and has at least one to relate on the sensitive data circuit 11, and described safeguard protection cover plate 23 is located on the described safe fence 22, and described safeguard protection cover plate 23 inside are equipped with protection cabling 231.
