Problems solved by technology

However, the current situation is that due to security considerations, after the personal digital identity authentication device is locked, the user often cannot unlock it by himself, but needs to go to a designated place to unlock the personal digital identity device. The digital identity authentication device resets the password or restores the initial password
This can cost a lot of time for both the user and the issuer of the personal digital identity authentication device

Embodiment Construction

[0017] In order to make the purpose, technical solution and effect of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. For the convenience of description, below, C1 is used to represent the number of failed password attempts, C2 is used to represent the value of locked times, F represents the locked flag, T1 represents the value of the timer, and T2 represents the value of the state of the timer.

[0018] F=0 is an unlocked state, and F=1 is a locked state. When C2=10, the personal digital identity authentication device cannot be automatically unlocked. The personal digital identity authentication device saves the timer state value every 600 seconds. The initial values ​​of C1, C2, T1, and F are all 0, and the initial value of T2 is set to 3600S, which is the specified time value for locking.

[0019] The detailed steps are as follows:

[0020] A) There are non-volat...

Abstract

The invention discloses a method for unlocking the locking state of personal digital identity identification equipment. After the personal digital identity identification equipment is locked, a user only needs to maintain the electrified time of the personal digital identity identification equipment to meet the required conditions, and he personal digital identity identification equipment can be automatically unlocked from the locking state. In the method, the personal digital identity identification equipment is unnecessarily returned to a seller for unlocking, and the user can directly complete the unlocking, and the unlocking process is simple, convenient and safe.

Description

technical field [0001] The invention belongs to the field of computer information security, and specifically relates to a method for unlocking a personal digital identity authentication device after it is locked. Background technique [0002] Usually, for personal digital identity authentication products such as smart cards, USB Keys, and smart key devices, the maximum number of retries for personal digital identity authentication devices is set by the developer. When the number of consecutive wrong passwords entered by the user reaches the maximum limit, the personal digital identity authentication device will be locked. At this time, even if the correct password is entered, corresponding operations cannot be performed; if only one input is correct within the maximum limit, The maximum number of retries reverted back to the maximum value set by the developer. This kind of personal digital identity authentication device is locked by continuously inputting wrong passwords, w...
