Problems solved by technology

Or when the mobile terminal is used by others, the application software will be accidentally deleted or damaged by others, resulting in loss of information in the application software
Especially when the mobile terminal is lost, other people may illegally use the bank client and other application software installed on the mobile terminal, which will bring huge losses to the user's property

Embodiment 1

[0072] figure 1 It is a flow chart of Embodiment 1 of a method for locking and unlocking an application of the present invention, which is applied to a trusted service management TSM platform. Embodiment 1 mainly describes the authorization of locking and unlocking, and the method includes:

[0073] Step 101: Receive a request instruction, where the request instruction includes a lock request instruction for requesting to lock a designated application software or an unlock request instruction for requesting to unlock a designated application software.

[0074] The request command received by the TSM platform may be a lock request command for locking one or all application software, or an unlock request command for unlocking one or all application software. For example, when lending the mobile terminal to others, you can only choose to lock several application software with private information, and when the mobile terminal is brought back, unlock the locked application software...

Embodiment approach

[0077] First possible implementation:

[0078] receiving the request instruction sent by the ISD through the TEE proxy, the request instruction is generated by the trusted application store according to the user's operation and sent to the ISD.

[0079] The user can open the trusted application store, and the trusted application store has icons of all application software installed on the mobile terminal, and the user clicks the operation button of locking or unlocking provided on the icon of the application software. After receiving the user's click operation, the trusted application store sends a lock request instruction or an unlock request instruction to the main security domain (Issue Security Domain, ISD). The ISD sends the lock request instruction or the unlock request instruction to the TSM through a Trusted Execution Environment (Trusted Execution Environment, TEE) agent. What needs to be explained here is that all communication information between the ISD and the TS...

Embodiment 2

[0115] figure 2 It is a flow chart of Embodiment 2 of a method for locking and unlocking an application of the present invention, which is applied to the main security domain ISD. Embodiment 2 mainly describes the authorization verification of locking and unlocking. The method includes:

[0116] Step 201: Receive the operation authorization information and operation instructions sent by the trusted service management TSM platform through a secure channel.

[0117] The operation authorization information and the operation instruction are generated according to the request instruction received by the TSM platform, the operation instruction corresponds to the request instruction, and when the request instruction is a lock request instruction, the operation instruction is a lock operation instruction, and when the request instruction is an unlock request instruction, the operation instruction is an unlock operation instruction.

[0118] The TSM platform sends the operation autho...

Abstract

The invention provides a locking and unlocking application method, device and system. The method comprises the following steps: receiving a request command by using a trusted service management (TSM) platform, and establishing a security channel with an issue security domain (ISD) through a trusted execution environment (TEE) agent by adopting a bidirectional authentication method; generating operation authentication information and an operation command according to the request command, transmitting the operation authentication information and the operation command to the ISD through the security channel, receiving the operation authentication information and the operation command by using the ISD, verifying whether the operation authentication information is correct or not, and executing the operation command when the operation authentication information is correct. By using the method, specified application software can be locked or unlocked, and locked application software cannot be operated, thereby avoiding information leakage or property loss caused by the use of the application software when a mobile terminal is borrowed or lost, and enhancing the security of the application software installed in the mobile terminal.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method, device and system for locking and unlocking applications. Background technique [0002] At present, the Android system has gradually become one of the commonly used operating systems for mobile terminals due to its good compatibility and high openness. Usually, users can freely install or uninstall various application software on the Android system, especially the rooted Android system, on the mobile terminal using it as the operating system. For example: game software, bank client software, chat software, shopping software, etc. Users can conveniently perform activities such as entertainment, transfer, chat or shopping through the application software installed on the mobile terminal. [0003] In life, users often encounter the situation that the mobile terminal is lent to others or lost. When the mobile terminal is used by others, some private info...
