Problems solved by technology

[0003] In the process of realizing the present invention, the inventor found that since the current dynamic token display passwords are all 6 or 8 digits, when the thief obtains the seed or multiple passwords, there is a risk of deciphering them in reverse, and the dynamic token Easily lost or stolen

Embodiment 1

[0052] In order to effectively prevent dynamic tokens from being stolen, dynamic tokens lost, seed files lost, and the possibility of group enumeration, the embodiment of the present invention provides a dynamic token working method, wherein the dynamic token is usually in Sleep state, wake up when a button is pressed, set the button flag, when the power button is pressed continuously for more than the preset time, or when there is no button input within the predetermined time, it will re-enter the sleep state, and the state flag will be restored at the same time is the default, saves the current number of available password retries and the current state of the lock flag.

[0053] When it is detected that the button flag is set and the dynamic token has not been initialized, the dynamic token detects whether the LCD screen and the keyboard are available according to the type of the pressed button;

Embodiment 2

[0095] In order to effectively prevent the dynamic token from being stolen, the loss of the dynamic token, the loss of the seed file, and the possibility of group enumeration, the embodiment of the present invention uses the power key and the delete key to share one key, and the number keys 1 to 9 are used as the first number key group, The number key 0 is taken as the second number key group as an example to provide a specific implementation method of a dynamic token provided in Embodiment 1, wherein the dynamic token is usually in a dormant state, and when a key is pressed When the power button is pressed down, it will be woken up, and the button flag will be set. When the power button is pressed continuously for more than the preset time, or there is no button input within the predetermined time, it will re-enter the dormant state, and at the same time restore the status flag to the default value and save the currently available The number of password retries and the current...

Embodiment 3

[0180] In order to effectively prevent dynamic tokens from being stolen, dynamic tokens lost, seed files lost, and the possibility of group enumeration, the embodiment of the present invention provides another dynamic token working method, wherein the dynamic tokens are usually It is in the dormant state and wakes up when a button is pressed, and the button flag is set. When the power button is continuously pressed for more than the preset time, or there is no key input within the predetermined time, it will re-enter the dormant state, and the status flag will be set at the same time. Reverts to default, saves the current number of available password retries, and the current state of the lock flag.

[0181] When it is detected that the button flag is set and the dynamic token has not been initialized, the dynamic token detects whether the LCD screen and the keyboard are available according to the type of the pressed button;

[0182] When it is detected that the button flag is ...

Abstract

Disclosed is a one-time password operating method, comprising: when a one-time password detects a valid key, judging the type of a pressed key, if the pressed key is a power-on key, detecting whether a current power-on logo is set, if yes, resetting same, otherwise, setting same and inspecting whether a locking logo is set, if yes, entering an unlocking code interface, otherwise entering an information interface; if the pressed key is a delete key, deleting data at the tail end of a data cache area; if the pressed key is a number key and the one-time password is not in the information interface, storing corresponding data in the data cache area; if the one-time password is in the information interface, judging whether the time for the key being pressed down goes beyond a preset time period, if yes, entering a power-on password modifying interface, otherwise storing corresponding data in the data cache area; if the pressed key is an Enter key and the one-time password is not in the information interface, judging whether the data in the data cache area are correct or meet requirements, if the one-time password is in the information interface, generating a dynamic password and displaying corresponding contents.

Description

technical field [0001] The invention relates to the field of information security, in particular to a working method of a dynamic token. Background technique [0002] In the prior art, dynamic token (One-time Password, OTP) is a safe and convenient account anti-theft technology, which generates an unpredictable combination of random numbers according to a special algorithm, and each password can only be used once, and the user During authentication, in addition to entering the account number and static password, a dynamic password must be entered. Only through the system verification can normal login or transaction be performed, thus effectively ensuring the legitimacy and uniqueness of the user's identity. The biggest advantage of dynamic tokens is that the passwords used by users are different every time, so that criminals cannot counterfeit the identity of legitimate users. Dynamic password authentication technology is considered to be one of the most effective ways to s...
