Problems solved by technology

[0004] However, with the existing solution, if the smart password device needs to perform the mode switching process during the pairing process with the external device, the smart password device will give priority to the mode switching process. Since the mode switching takes a certain amount of time, the pairing process often results in Timeout, which in turn causes the Bluetooth communication connection to be disconnected, and the Bluetooth communication between the smart password device and the external device fails

Embodiment 1

[0022] This embodiment provides a method for switching communication modes applied to smart cryptographic devices, such as Figure 1-2 As shown, because the flow process of this method includes many steps, it cannot be presented in one figure, so the complete method in this embodiment is presented in figure 1 and figure 2 in, of which figure 1 It shows that after the smart cryptographic device is turned on, it executes the process of establishing a Bluetooth communication connection, the process of Bluetooth security pairing, and the process of switching from the initial mode to the high-speed communication mode. figure 2 It shows switching from the high-speed communication mode to the initial mode, then switching from the initial mode to the low-speed communication mode, and how to jump execution again in the low-speed communication mode, so as to switch to the high-speed communication mode through the initial mode.

[0023] This embodiment provides a communication mode ...

Embodiment 2

[0060]This embodiment provides an intelligent cryptographic device. The intelligent cryptographic device is a device that can implement security operations such as digital signatures and identity authentication based on digital certificates. The intelligent cryptographic device can communicate with external devices (such as mobile phones, POS machines, PCs, etc.) cooperate with each other to complete the confirmation and signature of the transaction data during the transaction process. The smart password device is equipped with components such as a security chip, a screen for displaying data, a Bluetooth communication interface for realizing Bluetooth communication, a button for inputting confirmation instructions, and a Bluetooth button for triggering the establishment of a Bluetooth connection. There will be a Bluetooth button on the phone, so that users can manually control the opening and closing of the Bluetooth connection. It is understandable that when the smart passwor...

Abstract

The invention provides a switching method of a communication mode and intelligent password equipment. The method comprises the following steps: executing the process of establishing Bluetooth communication connection with external equipment by the intelligent password equipment under an initial mode; sending a Bluetooth safety pairing request to the external equipment; receiving a Bluetooth safety pairing response; after successfully pairing with the external equipment, sending a high-speed switching request to the external equipment, receiving the high-speed switching response, turning in a high-speed clock, turning on a power supply of a safety chip, and switching to the high-speed communication mode; performing the service data communication between the intelligent password equipment and the external equipment under the high-speed communication mode, and sending an initial switching request to the external equipment and receiving the initial switching response after the service data communication is completed; sending a low-speed switching request to the external equipment under an initial mode; receiving the low-speed switching response, turning off a screen, turning off the high-speed clock and turning off the power supply of the safety chip by the intelligent password equipment, and switching to the low-speed communication mode.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a communication mode switching method and an intelligent encryption device. Background technique [0002] After the smart password device supporting the Bluetooth communication interface successfully establishes a Bluetooth connection with an external device, it will perform data communication according to a certain fixed time period, which is called the communication connection interval. In order to increase the communication rate, a smaller communication connection interval is generally selected; and in order to reduce the power consumption of the smart cryptographic device, considering increasing the sleep time, a larger communication connection interval is generally selected. In different application scenarios, it is very important for smart cryptographic devices to select an appropriate communication connection interval to switch to an appropriate communication mode to c...
