Prevent that cracking intensity all greatly improves.
Below in conjunction with the embodiment of the method for electronic equipment anti-intrusion, technical solution is further illustrated.
The method comprising the steps of:
Pressure sensor is arranged in S301 in electronic equipment, and the both ends of the pressure sensor are butted in electronic equipment respectively
Opposite two sides, pressure sensor are compressed by two sides opposite in electronic equipment, have preset pressure；
It is provided with 2 or more pressure sensors in electronic equipment, in the pressure sensor, pressure more than at least two
There is force snesor different intrusion events to judge setting；
S302 receives the signal of pressure sensor, according to preset intrusion event judgement setting to the pressure of pressure sensor
Signal changes over time the pressure signal to be formed variation and is judged, judges whether pressure signal variation is that intrusion event causes
Pressure signal variation；
In order to save the power consumption of equipment anti-intrusion system, the mode of the signal for receiving pressure sensor is periodically
Intermittent reception pressure sensor signal, can use the processor of low-power consumption, and processor acquires the voltage of sensor using ADC.
Preset intrusion event judgement setting includes: the pressure signal value of the pressure signal value and preset pressure that will test
It is compared, if the difference between the pressure signal value detected and the pressure signal value of preset pressure exceeds preset range,
Judge that pressure signal variation changes for pressure signal caused by intrusion event.
In the equipment for being provided with multiple pressure sensors, judge whether pressure signal variation is caused by intrusion event
Pressure signal variation specifically includes: being arranged according to the preset intrusion event judgement of each pressure sensor to each pressure sensor
Pressure signal changes over time the pressure signal to be formed variation and is judged, if there is the pressure signal of at least one pressure sensor
The intrusion event judgement setting that the pressure signal to be formed variation meets the pressure sensor is changed over time, then judges that the pressure is believed
Number variation be intrusion event caused by pressure signal change.
To further improve safety performance, in some embodiments, it is passed with the pressure in a batch of distinct electronic apparatuses
There is sensor different intrusion events to judge setting, or with different preset pressures.
Whether it is arranged in multiple pressure sensors or same batch in same electronic equipment to different electronics
Pressure sensor in equipment uses different settings, and the preset pressure of each pressure sensor not instead of fixed value is being set
After being completed, the value of each pressure sensor is sampled out, and using the pressure value as a reference value of reference, that is, preset
The pressure value of pressure is written in equipment setting, the preset pressure value of the pressure sensor of equipment each in this way and equipment everywhere
It there is the difference of fit on, attacker accurately can not learn and crack.In use, once the pressure signal of pressure sensor
Change and be more than a reference value to a certain degree, then it is assumed that by security intrusion, trigger security mechanism.
The safe processor of this low-power consumption can periodical suspend mode, wake up, when suspend mode, reduces power consumption, when waking up work
The voltage of sensor is acquired, and is compared with reference value, if it exceeds certain range, then trigger security mechanism, is removed secret
Key.Periodical suspend mode, wake-up can reduce operating current, extend battery.During wake-up, safe processor, to electricity
The multiple pressure sensor K1~K5 being arranged in sub- equipment carry out sampling analysis.Can choose in embodiment 100ms~
The dormant and awakening period of 1000ms, this period had both taken into account the kwh loss of processor, also avoided too long suspend mode week
Phase gives invader's time enough and cracks to equipment.
To avoid falling, shaking, hitting, the interference of other unexpected factors to anti-intrusion system such as cooling thermal impact, electrostatic, keep away
Exempt to report by mistake, preset intrusion event judgement setting includes: periodically to detect the pressure signal of pressure sensor, when even
More than continuous n times, the difference between the pressure signal value of the pressure signal value detected and preset pressure exceeds preset range, sentences
Pressure signal variation of breaking is that pressure signal caused by intrusion event changes, and the n is greater than or equal to 2.Specifically in certain implementations
In example, intrusion event judgement setting is specifically included: being detected above signal to attack continuous 2 times, is then judged that the pressure signal changes
Whether it is the variation of pressure signal caused by intrusion event, if only detecting a signal to attack, is judged as interference signal, does not adopt
It is taken into and invades reply step.It in embodiment, can be continuous using being collected into during the detection in multiple dormant and awakening periods
Pressure signal variation is analyzed and determined, if adjacent 2 pressure signal the variations more than period are judged as signal to attack,
It is judged as intrusion event, takes safety measures.If only a cycle detects signal to attack, it is judged as interference.
Referring specifically to process step shown in Fig. 5, comprising:
The signal of S501 reception pressure sensor；
The pressure signal value that S502 will test is compared with the pressure signal value of preset pressure, judges the pressure detected
Whether the difference between force signal value and the pressure signal value of preset pressure exceeds preset range, if difference is without departing from default model
It encloses, then continues step S501, if difference exceeds preset range, carry out step
S503 adds up the difference between the pressure signal value detected and the pressure signal value of preset pressure beyond preset
The number m of range,
S504 judges whether m is greater than or equal to n, and n is preset numerical value, is greater than or equal to 2；If m is less than n, carry out
Step S501 carries out step if m is greater than or equal to n
S505 executes preset invasion and copes with step.

Power-time change waveform, it includes possible disturbed condition that these pressure versus times, which change waveform, such as falls, hits, is cold and hot
The waveform that the pressure that may cause when variation changes over time.The pressure signal received is changed the pressure to be formed by equipment
Power-time waveform is compared with preset waveform, if received pressure signal variation and preset interference signal pressure
The difference of signal intensity is greater than preset value, then is judged as signal to attack.
S303 changes if pressure signal caused by intrusion event, then executes preset invasion reply step.Different
In embodiment, invasion reply step can be the circuit for destroying storage sensitive data, destroying memory module, destroying need for confidentiality
Deng, these processes can complete physical destroying by heavy current impact, and the softwares such as data deletion can also be completed by software to be destroyed,
