If you want to confirm whether the master device is a device supported by the smart key device (that is, how to identify the communication parameter configuration of the master device), you need to use each scheme to try to communicate, but in practical applications, it is found that this implementation method is difficult. A fatal weakness, if the first library called is the library of the device supported by the smart key device, then if you connect another device, you need to try m*n kinds of solutions before you can determine whether the connected device is a smart key device. The device supported by the key device, and it takes about 50 seconds to complete this process, resulting in a low communication rate

Embodiment 1
[0244] Embodiment 1 of the present invention provides a method for quickly identifying device communication parameter configurations, such as figure 1 shown, including:
[0245] Step S0: The terminal device sends corresponding fast handshake instructions including downlink communication parameters to the connected smart key device through the first channel according to different downlink frequencies, and waits to receive the data returned by the smart key device;
[0246] For example, in this embodiment, the terminal device sends quick handshake instructions including downlink communication parameters to the smart key device in the order of a, a-1...2, 1 according to the preset a type of downlink frequency;
[0247] In this embodiment, after step S0 and before step S1, it further includes: the terminal device judges whether all the fast handshake instructions including downlink communication parameters have been sent, and if so, waits for the data returned by the smart key dev...
Embodiment 2
[0291] Embodiment 2 of the present invention provides a method for quickly identifying the communication parameter configuration of a device. The terminal device will save the communication parameter configuration of the smart key device every time it communicates with the smart key device, such as figure 2 As shown, the method of the present embodiment includes:
[0292] Step 201: The terminal device judges whether there is a smart key device connected to it, if yes, execute step 202, otherwise return to step 201;
[0293] Step 202: The terminal device judges whether it is connected to the smart key device for the first time, if yes, execute step 205, otherwise execute step 203;
[0294] Step 203: The terminal device negotiates the communication rate with the smart key device using the corresponding saved downlink communication parameters, and judges whether the negotiation is successful. If yes, execute step 204; otherwise, execute step 205;
[0295] Step 204: The terminal...
Embodiment 3
[0323] Embodiment 3 of the present invention provides a specific implementation process for a smart key device to receive a quick handshake instruction issued by a terminal device and analyze it, and judge whether the analysis is successful, as follows: image 3 As shown, the method of this embodiment includes:
[0324] Step 301: the smart key device waits for and receives the first byte of data sent by the terminal device;
[0325] Step 302: The smart key device judges whether the first byte data received is the first frame header data, if yes, store the first byte data received in the buffer in order, and execute step 303, otherwise return Step S3;
[0326] Preferably, the first frame header data in this embodiment is 0xca;
[0327] Step 303: the smart key device waits to receive the second byte of data sent by the terminal device;
[0328] Step 304: When the smart key device receives the second byte data, judge whether it is the second frame header data, if so, store the...

Abstract
The invention discloses a method, a system and a device for rapidly identifying communication parameter configuration. The method comprises the following steps that: when fast handshake instructions sent by terminal equipment are received, smart key equipment analyzesthe fast handshake instructions, acquires downlink communication parameter numbers from an analysisresult, saves the acquired downlink communication parameter numbers, and transmits corresponding uplink communication parameters and all the acquired downlink communication parameter numbers to the terminal equipment respectively through a second channel according to saved different uplink frequencies when the fast handshake instructions comprise a last downlink communication parameter or a data reception waiting time exceeds a preset duration; the terminal equipment analyzesthe received data, acquires the uplink communication parameters and all the downlink communication parameter numbers from the analysisresult, and saves the acquired uplink communication parameters and all the acquired downlink communication parameter numbers; and the terminal equipment acquires corresponding downlink communication parameters according to all the saved downlink communication parameter numbers, and determines the communication parameter configuration of the smart key equipment according to the acquired downlink communication parameters and all the acquired uplink communication parameters.
Description
technical field [0001] The invention relates to the field of information security, in particular to a method, system and device for quickly identifying communication parameter configurations. Background technique [0002] In the prior art, during the communication process between the smart key device and the app (application program), the smart key device is a slave device, and the host device of the app is the master device. Before the communication, the master device actively shakes hands with the slave device. The handshake is divided into downlink and uplink. If there are m kinds of schemes for the downlink existing app and n kinds of parameter configurations for the uplink, then there are m*n kinds of schemes for the handshake. If you want to confirm whether the master device is a device supported by the smart key device (that is, how to identify the communication parameter configuration of the master device), you need to use each scheme to try to communicate, but in pr...
