Abstract
The invention discloses a dynamic token with the key protection function and a working method of the dynamic token and belongs to the technical field of keys. The dynamic token comprises a master control module, a key module, a key forbidden timing module and a key abnormity timing module, wherein the master control module comprises a clock unit, a timing interrupt unit, an input interrupt unit and an input/output unit. The working method includes the steps that when the dynamic token detects that input interrupt happens to the input interrupt unit, the dynamic token is awakened, and input awakening identification is set; when the dynamic token detects that timing interrupt happens to the timing interrupt unit, the dynamic token is awakened, and timing awakening identification is set; if key awakening identification is set, key operation is executed, and if the timing awakening identification is set, the key protection procedure is executed. Through the technical scheme, power consumption caused by abnormal key operation on the dynamic token can be reduced, and the service life of the dynamic token is prolonged.

Row step 210；
It is preferred that described judge whether to be in massage protection state in the present embodiment, particularly as follows: judging that described button is protected
Shield identify whether set, if it is, described dynamic token is in massage protection state, otherwise described dynamic token be not in by
Key protection state；
Step 206: described dynamic token obtains the value that button disables timing module, judges described button disabling timing module
Value whether reach first threshold, if it is, execution step 207, otherwise return execution step 202；
In the present embodiment, button disabling timing module is synchronous with dynamic token internal clocking, when dynamic token internal clocking
When time increases by 1 second, button disables the corresponding increase of value 1 second of computing module it is preferred that first threshold is 5 seconds；
Can also be: when dynamic token internal clock time increases by 1 second, button disables the corresponding minimizing of value of timing module
1 second it is preferred that first threshold is 0 second；
Step 207: described dynamic token forbids described input interrupt location, described output pin is set to the second electricity
Flat, detect whether described input pin is the first level, if it is, execution step 209, otherwise execution step 208；
Wherein, Fig. 2 in embodiment 1, whether the input pin in the described I/O unit of described detection is the first electricity
Flat, particularly as follows: detecting whether the input pin (k1) in described I/O unit is high level；
Wherein, Fig. 3 in embodiment 1, whether the input pin in the described I/O unit of described detection is the first electricity
Flat, particularly as follows: detecting whether the input pin (k1) in described I/O unit is low level；
Wherein, Fig. 4 in embodiment 1, whether the input pin in the described I/O unit of described detection is the first electricity
Flat, particularly as follows: detecting whether the input pin (k1, k2, k3, k4) in described I/O unit is high level；
Wherein, Fig. 5 in embodiment 1, whether the input pin in the described I/O unit of described detection is the first electricity
Flat, particularly as follows: detecting whether the input pin (k1, k2, k3, k4) in described I/O unit is low level；
Step 208: the output pin in described I/O unit is set to the first level by dynamic token, will be described
The value that button disables timing module is set to the first initial value, returns execution step 202；
In the present embodiment, if made an appointment when dynamic token internal clocking increases by 1 second, button disables timing module
Value is corresponding to be increased by 1 second, then preferably, the first initial value is 0 second；
If making an appointment when dynamic token internal clocking increases by 1 second, the value that button disables timing module corresponds to minimizing 1
Second, then preferably, the second initial value is 5 seconds；
Step 209: dynamic token exits massage protection state, the value of button exception timing module is set to second initial
Value, returns execution step 202；
Wherein, described exit massage protection state, particularly as follows: by described massage protection identify reset；
In the present embodiment, button exception timing module is synchronous with dynamic token internal clocking, if it is dynamic to make an appointment
State token internal clock time increases by 1 second, and the value of button exception timing module is corresponding to be increased by 1 second, then this step is abnormal by button
The value of timing module is set to the second initial value 0 second；If dynamic token internal clocking of making an appointment increases by 1 second, button is counted extremely
When module value corresponding reduce 1 second, then the value of button exception timing module is set to the second initial value 10 seconds by this step；
Step 210: described dynamic token forbids described input interrupt location, by the output in described I/O unit
Pin is set to second electrical level, detects whether the input pin in described I/O unit is the first level, if it is,
Execution step 211, otherwise execution step 212；
Step 211: the value of described button exception timing module is set to the second initial value by described dynamic token, returns execution
Step 202；
Step 212: described dynamic token updates the value of described button exception timing module, and judges that described button is counted extremely
When module value whether reach Second Threshold, if it is, execution step 213, otherwise return execution step 202；
In the present embodiment, if button exception timing module is synchronous with dynamic token internal clocking, dynamic token
Internal clock time increases by 1 second, and the value updating button exception timing module is that the value of button exception timing module is corresponded to increase by 1
Second, then when the value of button exception timing module reaches Second Threshold 10 seconds, execution step 213；If button exception timing mould
Block and dynamic token internal clocking are asynchronous, then dynamic token internal clocking increases by 1 second, update button exception timing module
Value is to reduce 1 second by corresponding for the value of button exception timing module, then when the value of button exception timing module reaches Second Threshold 0 second
When, execution step 213；
Step 213: described dynamic token enters massage protection state, by the output pin in described I/O unit
It is set to the first level, the value that described button is disabled timing module is set to the first initial value；
In the present embodiment, if dynamic token internal clocking of making an appointment increases by 1 second, button disabling timing module corresponds to
Increase by 1 second, then this step by button disable timing module value be set to the first initial value 0 second；If making an appointment dynamic token
Internal clocking increases by 1 second, then button disabling timing module is corresponding reduces 1 second, then button is disabled the value of timing module by this step
It is set to the first initial value 5 seconds；
Step 214: described dynamic token closes display screen, and the state of described dynamic token is set to resting state, returns
Execution step 202；
In the present embodiment, the output pin in input pin and I/O unit in I/O unit is
One level, is capable of dynamic token and input can not be occurred to interrupt, when button is pressed, electric current does not increase, and so that dynamic token is entered low
Power consumption state.
