Embodiment 1
[0091] Embodiment 1 of the present invention provides a dynamic token with a key protection function, such as figure 1 As shown, it includes: a main control module 101, a display module 102, a key module 103, a power supply module 104, a key disable timing module 105 and a key abnormal timing module 106; wherein, the main control module 101 includes a clock unit 1011, a timing interrupt unit 1012, an input interrupt unit 1013 and an input / output unit 1014;
[0092] The main control module 101: connected with the input / output unit, used for controlling the output level of the input / output unit 1014; connected with the input interrupt unit, used for inputting the input / output unit 1014 When the preset level changes, the input interrupt unit 1013 is controlled to generate an input interrupt; it is connected to the clock unit and the timing interrupt unit, and is used to control the timing interrupt unit 1012 to generate an input interrupt triggered by the clock unit 1011 timed i...
Embodiment 2
[0130] Embodiment 2 of the present invention provides a working method of a dynamic token with key protection function on the basis of Embodiment 1, such as Image 6 shown, including:
[0131] Step 201: The dynamic token is powered on and initialized, the initial state of the input pin of the input / output unit is set as the first level, and the output pin of the input / output unit is initialized to the second level;
[0132] Among them, in embodiment 1 figure 2 , the initial state of the input pin of the input / output unit is taken as the first level, and the output pin of the input / output unit is initialized to the second level, specifically: the key in the key module ( Pin 1 of Key1) is connected to VCC through a resistor (R1), then the initial state of the input pin (K1) in the input / output unit is high level, and the output pin (K2) is initialized to low power flat;
[0133] Among them, in embodiment 1 image 3 , the initial state of the input pin of the input / output un...

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.
Description
technical field [0001] The invention relates to the field of button technology, in particular to a dynamic token with a button protection function and a working method thereof. Background technique [0002] A dynamic token is a terminal used to generate a dynamic password. The dynamic password can be used to confirm the legal identity of the user, thereby ensuring the security of the user's business access on the basis of the user logging in with a legal identity. Dynamic password authentication technology is considered to be one of the most effective solutions to user authentication at present, and thus is widely used in various information system scenarios such as banking, securities, third-party payment, and large enterprises. [0003] With the popularity of electronic products, the power consumption of buttons has become a topic that more and more manufacturers are scrambling to pay attention to. The length of use of electronic products directly affects the performance o...
