Embodiment 1

[0028]This embodiment provides an audio signal transmission method, which is applied to audio signal transmission between a smart key device and a mobile terminal. The smart key device can be a key for signing to ensure information security, a dynamic password token with the function of generating a dynamic password according to a challenge code, and a mobile terminal can be a laptop, tablet computer, mobile phone, smart watch, smart glasses, etc. with an audio interface device of. The smart key device and the mobile terminal can be connected through an audio interface. The audio interface of the smart key device matches the audio interface of the terminal. The smart key device is connected to the terminal through its audio interface and transmits audio signals. The smart key device The device can have an audio interface, and can also be converted to an audio interface through its USB interface; the smart key device and the mobile terminal can also transmit audio signals throu...

Embodiment 2

[0048] Compared with Embodiment 1, the audio signal transmission method provided in this embodiment differs in that the method described in Embodiment 1 is uplink transmission (the smart key device sends a waveform to the mobile terminal), and the method described in Embodiment 2 is Downlink transmission (mobile terminal sends waveform to smart key device).

[0049] Specifically, in Embodiment 2, the first few steps are the same as Step 101 to Step 104 shown in Embodiment 1. After the smart key device obtains the format information, the mobile terminal sends the second waveform according to the format information and the first encoding method ; The smart key device receives the second waveform, decodes the second waveform according to the format information and the decoding method corresponding to the first encoding method, and obtains valid data in the second waveform.

[0050] In this embodiment, the mobile terminal sends the format information of the waveform corresponding ...

Embodiment 3

[0052] This embodiment provides a mobile terminal, which can be used to implement the audio signal transmission methods described in Embodiment 1 and Embodiment 2. Such as figure 2 As shown, the mobile terminal includes the following modules:

[0053] The encoding module 21 is configured to encode the format information of the waveform corresponding to the audio signal according to the first encoding method used by the mobile terminal to transmit the waveform corresponding to the audio signal to obtain the first encoded data, wherein the format information includes: valid data; the length of the pre-frame guard field before the data; the length of the end-of-frame guard field after the valid data; and the length of the start field field for determining the start of the valid data after the pre-frame guard field and before the valid data;

[0054] A sending module 22, connected to the encoding module 21, configured to send the first waveform corresponding to the first encoded...

Abstract

Disclosed are an audio signal transmission method, mobile terminal and intelligent key device, the method comprising: a mobile terminal encodes, according to a first encoding mode, the format information of a wave form corresponding to an audio signal to obtain encoded data, the format information comprising valid data, the length of a [O1] protection field at the beginning of a frame and before the valid data, the length of a protection field at the end of the frame and after the valid data, and the length of an initiator domain field after the protection field at the beginning of the frame, and before the valid data, for determining the beginning of the valid data; the mobile terminal transmits a first wave form corresponding to the encoded data; after receiving the first wave form, an intelligent key device decodes the first wave form according to a decoding method corresponding to the first encoding mode so as to obtain the format information; the intelligent key device transmits a second wave form according to the format information and the second encoding mode; and according to the format information and the decoding method corresponding to the second encoding mode, the mobile terminal decodes the received second wave form to obtain the valid data in the second wave form.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an audio signal transmission method, a mobile terminal and an intelligent key device. Background technique [0002] At present, smart key devices (for example, electronic signature devices with signature functions or OTP tokens with password generation functions) can communicate with mobile terminals such as mobile phones and tablet computers through audio interfaces, that is, by transmitting waveforms corresponding to audio signals Realize the effective data transmission between the smart key device and the mobile terminal. [0003] During the process of sending and receiving data by the mobile terminal through the audio interface, the data transmitted by the mobile terminal may be lost. Therefore, how to solve the problem of data loss is an urgent problem to be solved. Contents of the invention [0004] The invention provides an audio signal transmission method, a mobile...
