Embodiment 1

[0043] This embodiment provides a method for controlling the working state of a dynamic token, figure 1 It is a flow chart of the control method of the dynamic token working state provided by Embodiment 1 of the present invention, such as figure 1 As shown, the method includes the following steps:

[0044] Step S101 , detecting the remaining power percentage of the battery of the dynamic token, wherein the battery is a rechargeable battery.

[0045] Of course, it is also possible to detect the terminal voltage of the battery. In fact, there is a certain relationship between the terminal voltage of a battery or a battery pack and the remaining power of the battery. The relationship curve between these two physical quantities can be obtained through measurement, so as to detect a physical quantity, and the other corresponding to it can be obtained according to the relationship curve. A physical quantity, the detection method is more flexible.

[0046] Step S102, if the percen...

Embodiment approach

[0063] The measures for reducing power consumption in the power-saving state have been described, and this embodiment further provides a preferred implementation mode: the power-saving state includes the first power-saving state and the second power-saving state; if the remaining power percentage is less than or equal to the first Threshold and greater than the fourth threshold, the dynamic token is controlled to enter the first power-saving state, and the dynamic token is in the first power-saving state, at least one of the following methods is used to reduce the power consumption of the dynamic token: reduce the brightness of the display screen and shorten the background Lighting time; if the remaining power percentage is less than or equal to the fourth threshold and greater than the second threshold, control the dynamic token to enter the second power-saving state. In the second power-saving state, the dynamic token only maintains clock power supply, and the dynamic token A...

Embodiment 2

[0071] In this embodiment, on the basis of Embodiment 1, a solution for calculating the estimated charging time is added. After entering the charging state, the estimated charging time is calculated according to the capacity and charging current of the battery. Preferably, the estimated charging time T can be calculated using the following formula: Among them, T d is the expected standby time, I d is the standby current, T w is the expected working time, I w is the working current, I s is the charging current. During the charging process, the estimated charging time can be displayed in real time on the display screen of the dynamic token, so that the user knows when the charging is complete and avoids overcharging.

[0072] Still taking the values ​​in Example 1 as an example to calculate the estimated charging time T:

[0073] T = T d × I ...

Abstract

The invention discloses a dynamic token working state control method and device and a dynamic token. The dynamic token working state control method comprises the steps of detecting the percentage of the remaining electricity quantity of a dynamic token battery, wherein the battery is a rechargeable battery; enabling the dynamic token to be in a using state and enabling the dynamic token in the using state to receive an instruction and then generate a dynamic password if the percentage of the remaining electricity quantity is larger than a first threshold value; enabling the dynamic token to be in an electricity-saving state if the percentage of the remaining electricity quantity is smaller than or equal to the first threshold value and larger than a second threshold value, wherein the electricity consumption is reduced and the clock power supply is maintained when the dynamic token is in the electricity-saving state; destroying the dynamic token if the percentage of the remaining electricity quantity is smaller than the second threshold value. The dynamic token adopts the rechargeable battery and can be circularly used in a rechargeable mode, and the service life of the dynamic token is prolonged. The electricity quantity of the battery is detected in real time, and the remaining electricity quantity is protected when the electricity quantity is reduced up to the certain degree, parts of functions of the token are limited to achieve electricity saving, and the stand-by time of the token is prolonged. The token is destroyed when the electricity quantity is too low, and the correctness of the dynamic token is ensured.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method and device for controlling the working state of a dynamic token and the dynamic token. Background technique [0002] The dynamic token OTP (OneTimePassword) is a terminal used to generate dynamic passwords. OTP generates a time-related, unpredictable combination of random numbers every 60 seconds according to a special algorithm, that is, a dynamic password, and each dynamic password is valid once. OTP generates 6-digit / 8-digit dynamic numbers and uses one-time pad for authentication. [0003] When using a dynamic token based on time synchronization, it is necessary to compare the time of the dynamic token with the time of the dynamic password verification server. This technology not only requires the verification server to be able to maintain the correct clock very accurately, but also has strict requirements on the crystal oscillator frequency of the dynamic toke...
