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

[0102] 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.

[0103] The acquisition module 201 is configured to receive a transaction request sent by a 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: a transaction amount. The security module 202 is configured to obtain at least one second unit data package stored by itself, wherein each second unit data package represents one currency denomination in multiple currency denominations,...

Abstract

The invention provides a trade method and trade system of an electronic signature device, and an electronic signature device. The trade method comprises the following steps: a first electronic signature device receiving a trade request sent by a second electronic signature device, wherein the trade request at least comprises a trade sum; the first electronic signature device obtaining at least one second unit data packet from a security chip, wherein each second unit data packet represents one currency face value among multiple currency face values, the total of the currency face values represented by the at least one second unit data packet is equal to the trade sum, and the second unit data packet comprises second unit data and data obtained by a server through signing the second unit data; and the first electronic signature device sending the at least one second unit data packet to the second electronic signature device. By use of the technical scheme provided by the invention, secure offline electronic trade can be realized.

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...
