Embodiment 1

[0058] figure 1 It is a flowchart of a transaction method for an electronic signature device provided in this embodiment. Such as figure 1 As shown, the transaction method includes the following steps S11-S13:

[0059] Step S11, the first electronic signature device receives the transaction request sent by the second electronic signature device, wherein the transaction request includes at least: transaction amount;

[0060] In this embodiment, the first electronic signature device and the second electronic signature device can conduct offline transactions (that is, they do not need to be connected to the server to complete the transaction), and both can be electronic devices with signature functions, for example, electronic devices with signature functions Smart cards (bus cards, bank cards, shopping cards, etc.), ICBC U-Shield, etc. In an optional implementation of this embodiment, both the first electronic signature device and the second electronic signature device can be...

Embodiment 2

[0100] 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 a first electronic signature device 20 and a second electronic signature device 30, wherein the electronic signature device (the electronic signature device in this embodiment is the first electronic signature device 20) includes an acquisition module 201, a security module 202 and communication module 203. Wherein, the obtaining module 201 is configured to receive a transaction request sent by the peer electronic signature device (the peer electronic signature device is the second electronic signature device 30 in this embodiment), wherein the transaction request includes at least: transaction amount. The security module 202 is configured to acquire at least one second unit data package stored by itself, wherein each second unit data package represents a currency denomination in multiple currency denominations, an...

Abstract

The invention provides electronic signature devices, and a trading method and a trading system thereof, and the trading method comprises: a first electric signature device receives a trading request sent by a second signature device, wherein the trading request at least comprises transaction amount; the first electronic signature device acquires at least one second unit data package from a security chip of the first electronic signature device, wherein each second 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 first electronic signature device sends the above at least one second unit data package to the second electronic signature device. 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...
