Embodiment 1

[0101] Embodiment 1 of the present invention provides a method for handling exceptions, such as figure 1 shown, including:

[0102] Step 101: The mobile terminal initializes, organizes the data to be signed, and generates a signature instruction according to the data to be signed;

[0103] In this embodiment, the initialization specifically includes: setting the screen status to highlight, initializing the number of PIN code verifications, setting the number of signature command sending times to the initial value, setting the number of signature result acquisition times to the initial value, resetting the abnormal event flag, and starting System event monitoring service.

[0104] Among them, after the mobile terminal is initialized, it also includes: receiving the PIN code input by the user, judging whether the PIN code is correct, if so, organizing the data to be signed, otherwise reporting an error, and ending;

[0105] Specifically, the mobile terminal generates a verific...

Embodiment 2

[0128] Embodiment 2 of the present invention provides a method for handling exceptions, such as figure 2 and image 3 shown, including:

[0129] Step 201: Start the mobile terminal, set the screen state to be highlighted, initialize the number of times of PIN code verification, set the number of command sending times as the initial value, set the number of times of obtaining signature results as the initial value, and set the number of times of obtaining key state as the initial value, Reset the abnormal event identification and start the system event monitoring service;

[0130] Wherein, the mobile terminal sets the screen state to be highlighted, specifically: the mobile terminal sets the idleTimerDisabled system attribute of the mobile terminal to YES, so as to prevent a black screen abnormal event from occurring when the communication is not completed;

[0131] In this embodiment, the mobile terminal receives the event message sent by the system to the mobile terminal t...

Embodiment 3

[0198] Embodiment 3 of the present invention provides a device for handling exceptions, such as Figure 4 shown, including

[0199] Instruction generation module 1: used to organize the data to be signed, and generate signature instructions according to the data to be signed;

[0200] Sending module 2: used to send the signature command to the smart key device, and also used to send the command to obtain the signature result to the smart key device;

[0201] Receiving module 3: used to receive the response returned by the smart key device;

[0202] The first judging module 4: used to judge whether a successful response returned by the smart key device is received within a preset time; it is also used to judge whether the number of times of sending signature instructions reaches the preset number of times;

[0203] The second judging module 5: used for judging whether there is an abnormal event when the first judging module judges that the successful response returned by the ...

Abstract

The present invention discloses a method and device for handling exceptions, which belong to the field of information security. The method includes: A: A mobile terminal organizes a signature command and sends it to a smart key device. If a returned response is received within a preset time, Then execute B, otherwise send the signature command again for the preset number of times; B: The mobile terminal judges whether there is an abnormal event, if there is an abnormal event, judges whether the duration of the abnormal event reaches the preset value, and ends if it is, otherwise executes B, if not If there is an abnormal event, send an instruction to obtain the signature result to the smart key device, and receive a returned successful response. By adopting the technical scheme of the present invention, when the smart key device communicates with the mobile terminal, different exception handling methods are adopted for different instructions, which can achieve the goal of normal program operation when an exception occurs more safely and conveniently.

Description

technical field [0001] The invention relates to the field of information security, in particular to a method and device for handling exceptions. Background technique [0002] The smart key device is a secure carrier of digital certificates and private keys based on the public key system, which can achieve reliable identity authentication and data encryption. At present, with the development of mobile banking (Mobile Banking Service, also known as mobile banking), smart key devices based on mobile terminals have emerged. To connect and communicate with mobile terminals. [0003] In the prior art, when the smart key device communicates with the mobile terminal, if it encounters an abnormal situation such as an incoming call, a text message or an alarm clock, it will immediately interrupt the communication, exit the mobile terminal, and will not save the communication status and user input before the abnormal situation occurs. information, when the mobile terminal restarts, i...
