Embodiment 1

[0023] figure 1 It is a structural diagram of the hardware wallet provided by the present invention. Such as figure 1 As shown, the hardware wallet includes an SE (SecureElement) security unit 110 , a main control unit 120 , a power management module 130 , a key module 140 , a display unit 150 , an antenna 180 , and also includes a USB interface 160 and / or a Bluetooth module 170 .

[0024] The SE security unit 110 is connected with the antenna 180 for Near Field Communication (NFC), and the SE security unit 110 controls the power management module 130 to turn on and off under certain conditions. The SE security unit 110 stores the private key of the hardware wallet. In the shutdown state, the SE security unit 110 and the antenna 180 work independently, establish NFC communication connections with terminal devices such as mobile phones through the antenna 180, and can realize hardware wallet creation, transaction and other services without turning on the power management modu...

Embodiment 2

[0033] The invention also provides a processing method of a hardware wallet based on NFC connection. Such as figure 2 As shown, the processing method includes the following steps:

[0034] S210: In response to receiving the NFC signal, the SE security unit establishes a near field communication connection with the terminal device. Specifically, the user can put the hardware wallet on the back of the mobile phone, and connect and communicate with the APP on the terminal through the terminal device.

[0035] S220: The SE security unit receives transaction information of the terminal device.

[0036] S230: The SE security unit decrypts and analyzes the transaction information, and obtains the processed transaction information, and the processed transaction information includes the transaction amount.

[0037] S240: Determine whether the transaction amount is less than the transaction amount threshold built in the SE security unit. If yes, execute S250; otherwise, execute S26...

Embodiment 3

[0047] The invention also provides a processing method of a hardware wallet based on USB or bluetooth connection. After the hardware wallet is connected to the terminal device via USB or Bluetooth, such as image 3 As shown, the processing method includes the following steps:

[0048] S310: The main control unit receives the transaction information of the terminal device through the USB or Bluetooth interface, and forwards it to the SE security unit.

[0049] S320: The SE security unit decrypts and analyzes the transaction information, and obtains the processed transaction information, and the processed transaction information includes the transaction amount.

[0050] S330: The SE security unit judges whether the transaction amount is less than the transaction amount threshold built in the SE security unit. If the transaction amount is less than the transaction amount threshold, execute S340; otherwise, execute S350.

[0051] S340: The SE security unit signs the transaction...

Abstract

The invention discloses a hardware wallet, and a hardware wallet processing method, and relates to the technical field of digital assets. A specific implementation mode of the hardware wallet comprises: an SE security unit, a main control unit, and a power supply management module; the SE security unit is connected with an antenna for near field communication; in a shutdown state, the SE security unit and the antenna work independently, and the antenna is in near field communication with terminal devices; the SE safety unit controls the power supply management module to be turned on and turned off under specific conditions; the main control unit is connected with the SE security unit; the power supply management module supplies power to the main control unit. According to the hardware wallet provided by the embodiment of the invention, the security of large-amount transactions and the portability of small-amount transactions are guaranteed, the power consumption of power supplies is also reduced, and the standby time of a hardware wallet is prolonged.

Description

technical field [0001] The invention relates to the technical field of digital assets, in particular to a hardware wallet and a processing method thereof. Background technique [0002] The hardware wallet stores the private key of the user's digital currency and is generally offline; only when in use is it connected to the application software of mobile phones, PCs and other terminal devices through USB, Bluetooth or QR codes to complete the transaction Signature, payment and other functions. [0003] At present, these methods can effectively prevent tampering and attacks by hackers and illegal personnel in terms of security; however, this device generally contains a rechargeable battery, and the hardware wallet is frequently operated, which requires relatively high battery power. If it is turned on every time a transaction is made, the battery power of the hardware wallet will be consumed, and a larger battery may be required to increase the charging interval to improve th...
