Embodiment Construction

[0017] The present invention will be further described below in conjunction with examples.

[0018] A transferable conditional electronic payment system has a payment platform, a bank, a payer, an account of the payer, and at least one payee, comprising the following steps:

[0019] (1) Payment generation, wherein, when the payer wishes to withdraw a currency from the bank, the payer needs to prove the ownership of the payer’s account and negotiate a public information, and the two parties pass a withdrawal agreement, Eventually said payer gets the currency cashed by the bank;

[0020] (2) Conditional transfer, wherein, when the payer wishes to pay his currency to the payee; the three random numbers generated by the payee and known information are used between the two parties to perform operations and bilinear pairing Verification, after the verification is passed, the payee will accept the currency sent by the payer.

[0021] (3) User registration, an interaction agreement ...

Abstract

The invention discloses a conditional electronic payment system with transferability. The conditional electronic payment system comprises a payment platform, a bank, a payer, a payer account and at least one payee. The conditional electronic payment system is characterized by including the steps: (1) generating payment; (2) transferring conditions; (3) registering a user; (4) additionally transferring; (5) cashing the payment; and (6) identifying double payers. The conditional electronic payment system has the advantages that by constructing the conditional electronic payment system, inefficient segmentation and selection technology and complicated knowledge proof agreements are omitted, and online requirements of the bank at any time in all conditional transfer agreements are eliminated. The conditional electronic payment system has transferability, and a series of payees can disguisedly further transact currency.

Description

technical field [0001] The invention relates to the field of electronic payment, in particular to a transferable conditional electronic payment system. Background technique [0002] The electronic payment prototype (or electronic cash prototype) proposed by Chaum can be said to be one of the most important applications of modern cryptography. After it was proposed, a large amount of research work has been completed in the past 30 years. There are two types of e-cash schemes which are online and offline. Online e-cash solutions can provide good solutions to the most difficult problems in e-cash solutions, such as the double payment problem. However, it requires the recipient to contact the bank for every transaction, which requires the bank to be online at all times. In other words, banks will soon become the bottleneck for the development of this system. Therefore, offline solutions are more attractive when building electronic cash systems. [0003] Shi et al. first pro...
