Embodiment 1

[0054] 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:

[0055] 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;

[0056] 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 ...

Embodiment 2

[0098] 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:

[0099] The second electronic signature device 30 is configured to send a transaction request to the first electronic signature device 20, wherein the transaction request includes at least: transaction amount. The first electronic signature device 20 is configured to receive a transaction request, obtain at least one second unit data packet from its security chip, and use an exclusive OR factor to at least perform exclusive OR on the second unit data in each second unit data packet operation to obtain at least one third unit data packet, and send the at least one third unit data packet to the second electronic signature 30 device, wherein the second unit data packet at least includes: currency denomination data and currenc...

Abstract

The invention discloses a trade method and trade system of an electronic signature device. The trade method comprises the following steps: a second electronic signature device sending a trade request including a trade sum to a first electronic signature device; the first electronic signature device receiving the trade request and obtaining at least one second unit data packet from a security chip, at least performing XOR operation on second unit data in each second unit data packet by use of an XOR factor to obtain at least one third unit data packet, and sending the at least one third unit data packet to the second electronic signature device; and the second electronic signature device receiving the at least one third unit data packet, respectively performing the XOR operation on data ciphertexts in each received third unit data packet by use of the XOR factor to obtain the at least one second unit data packet, and storing the at least one second unit data packet in the security chip.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a transaction method and a transaction system of an electronic signature device. 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 transactions rely on the bank server, an...
