Embodiment 1

[0051] figure 1 It is a flowchart of a transaction method for an electronic signature device provided in this embodiment. figure 1 The method embodiment shown comprises the following steps:

[0052] Step S11, the second electronic signature device sends a transaction request to the first electronic signature device, wherein the transaction request includes at least: transaction amount.

[0053] 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 provided with a wired interfac...

Embodiment 2

[0099] This embodiment provides a transaction system and an electronic signature device applied to the transaction system. 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 first electronic signature device 20 is used to receive the transaction request sent by the second electronic signature device 30, and send at least one second unit data packet to the second electronic signature device 30; The electronic signature device provided in the embodiment) includes a communication module 301 , an acquisition module 302 and a security module 303 .

[0100] The communication module 301 is configured to send a transaction request to the peer electronic signature device (that is, the first electronic signature device 20 in this embodiment), wherein the transaction request includes at...

Abstract

The invention provides a transaction method and transaction system for an electronic signature realization device, and an electronic signature realization device. The transaction method comprises: a second electronic signature realization device sends a transaction request to a first electronic signature realization device and receives at least one second unit data packet sent by the first electronic signature realization device, wherein each second unit data packet represents one kind of currency denomination among a plurality of currency denominations, each second unit data packet at least includes second unit data and third signature data obtained by signing second unit data by a server, and the second unit data at least include currency denomination data and currency serial numbers being unique identifiers of the second unit data packets; and the second electronic signature realization device verifies the third signature data and stores the at least one second unit data packet into a safety chip after successful verification.

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...
