Unlocking method and device

Abstract

The invention discloses an unlocking method and device, and the method comprises the steps that a secret key management system obtains the terminal identification information, transmitted by a user through other terminals, of a first terminal; the secret key management system determines a first dynamic signal set to be corresponding to the terminal identification information based on the terminalidentification information; the secret key management system transmits the first dynamic signal to the first terminal, and triggers the first terminal to carry out the TF password unlocking of the first terminal based on the first dynamic signal. Therefore, the secret key management system can transmit the first dynamic signal set to be corresponding to the terminal identification information of the first terminal to the first terminal, and triggers the first terminal to unlock a local TF password card, thereby achieving the remote unlocking of the TF password card of the first terminal so asto save manpower and equipment resources, and improving the unlocking efficiency of the TF password card and user experience.

Description

technical field [0001] The invention relates to the field of smart technology, in particular to an unlocking method and device. Background technique [0002] With the development of intelligent technology, terminals use external memory (TransFlash, TF) password cards to realize functions such as cryptographic algorithm calculation, random number generation, key generation, key storage and certificate storage, so as to encrypt voice calls and improve voice quality. Call security. [0003] However, under the existing technology, because the user needs to enter the corresponding password to obtain the corresponding authority of the TF password card in the terminal, if the wrong password is entered many times, the TF password card will be locked, so the user needs to send the terminal to In the business hall, after the staff verify the user's identity, the operation management terminal unlocks the TF password card. [0004] Obviously, the user sends the terminal to the busines...

Problems solved by technology

[0003] However, under the existing technology, because the user needs to enter the corresponding password to obtain the corresponding authority of the TF password card in the terminal, if the wrong password is entered many times, the TF password card will be locked, so the user needs to send the terminal to Go to the business hall, after the staff verify the user's identity, operate the management terminal to unlock the TF password card

[0004] Obviously, the user sends the terminal to the business hall to unlock the local TF password card, which will consume a lot of manpower and equipment resources, reduce the efficiency of unlocking the TF password card, and bring inconvenience to the user
