Embodiment 1

[0038] figure 1 It is a flowchart of a transaction method for an electronic signature device provided in this embodiment. figure 1 The shown method embodiment includes the following steps S11 to S13:

[0039] Step S11, the electronic signature device sends a transaction request to the server, wherein the transaction request includes at least: transaction amount.

[0040] In this embodiment, the electronic signature device may be an electronic device with a signature function, for example, a smart card with a signature function (bus card, bank card, shopping card, etc.), an ICBC U-shield, and the like. In an optional implementation manner of this embodiment, the electronic signature device may establish a connection with an external device (such as a PC or a mobile terminal, etc.), and the transaction request is sent to the server through the external device. Alternatively, the electronic signature device has a wired or wireless interface, establishes a wired or wireless conn...

Embodiment 2

[0068] figure 2 It is a schematic structural diagram of a trading system provided in this embodiment. Such as figure 2 As shown, the transaction system includes an electronic signature device 20 and a server 30 , wherein the electronic signature device 20 includes: a communication module 201 , an acquisition module 202 and a security module 203 .

[0069] The communication module 201 is used to send the transaction request to the server 30, wherein the transaction request includes at least: transaction amount; the acquisition module 202 is used to receive at least one first unit data packet from the server 30, wherein each first unit data The package represents one currency denomination among multiple currency denominations, and the sum of the currency denominations represented by the at least one first unit data package is equal to the transaction amount; the security module 203 is configured to store the at least one first unit data package.

Abstract

The invention provides an electronic signature device, and a trading method and a trading system thereof. The trading method comprises that the electronic signature device sends a transaction request to a server, wherein the transaction request at least comprises transaction amount; the electronic signature device receives at least one first unit data package, wherein each first unit data package represents a kind of currency denomination of multiple currency denominations, and the sum of currency denominations represented by the at least one second unit data package is equal to the transaction amount; and the electronic signature device saves the above at least one second unit data package in a security chip. The technical scheme provided by the invention is adopted to realize safe off-line electronic transaction.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a transaction method of electronic signature equipment, a transaction system and electronic signature equipment. Background technique [0002] In the existing electronic transactions, the user's funds are stored in the account in the form of numbers. For example, if the user holds 100 yuan of funds, the funds are stored in the user account of the bank server in the form of numbers. When the user consumes 10 yuan , the bank server needs to rewrite the funds in the user account from 100 to 90 to complete the settlement of the account. In order to ensure the security of the fund value, after the bank server rewrites the value, it is necessary to sign the rewritten fund value 90. Because the value of the amount in the account of the user will change after each transaction, the bank server must process the value after each change. That is to say, the existing electronic transact...
