A method and device for unlocking

Abstract

The invention discloses an unlocking method and device. The method is that a key management system acquires terminal identification information of a first terminal sent by a user through other terminals; the key management system determines the setting of the corresponding terminal identification information based on the terminal identification information. The first dynamic signaling; the key management system sends the first dynamic signaling to the first terminal, triggering the first terminal to unlock the TF encryption card of the first terminal based on the first dynamic signaling. In this way, the key management system can send the first dynamic signaling corresponding to the terminal identification information of the first terminal to the first terminal, triggering the first terminal to unlock the local TF cipher card, thereby realizing the TF encryption of the first terminal. The password card is unlocked remotely to save manpower and equipment resources, improve the efficiency of TF password card unlocking, 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. Therefore, 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...

Problems solved by technology

[0003] However, under the existing technology, since 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 for many times, the TF password card will be locked. Therefore, 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
