Problems solved by technology

The brute force attack based on the symmetric algorithm will lock the application in a short time, causing the device to fail to work normally
Similar to ETC without parking tolls, if high-power attack equipment is used, all vehicles entering the toll booth will be locked, causing road congestion and disrupting the operation of the electronic interconnection system

Embodiment 1

[0034] figure 1 It is a schematic structural diagram of the blockchain hard wallet of this application. like figure 1 As shown, the blockchain hard wallet of this application includes: a main control unit 1 for account balance records, transaction signatures, decentralized derivation of public keys, signature verification, transaction information records and communication with the outside world; communication unit 2 for Data interaction with the client.

[0035] Specifically, the main control unit 1 of this application manages account balances based on asymmetric algorithms, manages keys, distributes derivation of the other party's public key, verifies the other party's signature, signs its own account and transaction information, and signs the transaction information sent by the other party.

[0036] Specifically, the communication unit 2 is connected to the user equipment through USB or Bluetooth, and the main control unit 1 performs data interaction with the user equipmen...

Embodiment 2

[0042] This embodiment provides a method for a blockchain hard wallet to support off-chain transactions, which is applicable to the hard wallet described in Embodiment 1. figure 2 It is the flow chart of the method for the blockchain hard wallet of this application to support off-chain transactions, such as figure 2 As shown, the blockchain hard wallet of this application supports off-chain transaction methods, including:

[0043] Step T1. The user signs a contract with the electronic toll collection system, deposits funds in advance, deposits the initial fund balance in the hardware wallet, and publishes the funds on the blockchain node; the hardware wallet and the electronic toll collection system generate the initial public-private key pairs of their respective funds, and exchange each other's initial public key;

[0044] Among them, the type of the blockchain node is: multi-node type (2-of-2multisign).

[0045] Preferably, in step T1, the hardware wallet and the electron...

Abstract

The invention discloses a a method for supporting offline transactions by the block chain hard wallet and a hard wallet, relates to the technical field of digital currency, solves the technical problem that the existing hard wallet easily causes equipment locking. The block chain hard wallet comprises a main control unit which is used for account balance recording, transaction signature, decentralized derivation of public keys, signature verification and transaction information recording and is communicated with the outside; And the communication unit is used for performing data interaction with a user side. The method is mainly used for the electronic toll collection system.

Description

technical field [0001] The present application relates to the technical field of digital currency, and specifically relates to a method for a blockchain hard wallet to support off-chain transactions and the hard wallet. Background technique [0002] The financial technology system built on the basis of blockchain technology, due to its characteristics of distributed and encrypted numbers, the security of data records is very high, and it has broad application prospects in many fields such as finance, credit information, and the Internet of Things. Compared with traditional central server processing, the timeliness is lower, and it cannot meet the timely processing of large-scale transactions. The lightning network encrypts the signatures of both parties at the same time, and the transaction can be sent to the outside world. A special payment channel is established between the two parties. Small and frequent transactions only occur between the two parties. The final transacti...
