Problems solved by technology

However, these methods are inseparable from the online payment method of the network. When the network, GPRS, 3G, 4G and other communications are interrupted, the payment cannot be carried out. Therefore, we hope to have a payment method that can realize offline transactions-offline payment , used to solve the problem that the payment cannot be completed when the network communication is interrupted

Embodiment

[0048] The dual-medium dual-authentication fast offline payment method under the public key system of the present invention, the specific implementation steps are as follows:

[0049] Establish a set of VLC and Barcode public key system dual-media offline payment device, including: electronic wallet 1, consumer machine 2, and server 3.

[0050] The electronic wallet 1 includes: a control module 11 , an input module 12 , a display module 13 , a data interface 14 , a barcode scanning module 15 , a wallet module 16 , a visible light emission module 17 , and a password processing module 18 .

[0051] The visible light emitting module 17 is configured to generate and send a visible light signal according to the information input by the control module 11 .

[0052] The barcode scanning module 15 is used to scan and identify the barcode, and output the identification result to the control module 11 .

[0053] The control module 11 is used to: 1. Process the information to be sent, g...

Abstract

The invention discloses a double medium and double authentication fast off-line payment method under a public key system, which comprises the steps that a double medium off-line payment device under a VLC (Visible Light Communication) and Barcode public key system is built, wherein the double medium off-line payment device comprises an electronic wallet, a consumption machine and a server; implementation of the payment method is accomplished by the consumption machine and the electronic wallet; the electronic wallet sends visible light signals in the payment process and scans a barcode displayed by the consumption machine; and the consumption machine receives the visible light signals and generates a display barcode provided for the electronic wallet to scan. Mutual verification is performed on the identity and transaction information of the consumption machine and the electronic wallet by adopting the public key system, and the security of the off-line payment method and the non-repudiation of the two transaction parties are effectively improved.

Description

technical field [0001] The invention belongs to the field of visible light payment, in particular to a dual-medium dual-authentication fast offline payment method under the public key system. Background technique [0002] The public key cryptosystem is also called asymmetric cryptosystem, which is an important branch of modern cryptography. Under the public key system, a public key and a private key are provided, and the two parties in the communication use different keys for encryption and decryption. , the public key cryptosystem does not have the security problem of key distribution. This method is widely used in electronic authentication related fields such as electronic signature and digital certificate, and has been applied in e-commerce and e-government. [0003] Offline payment is a transaction payment method that can break away from network restrictions and server online verification for each transaction, and can be completed only by consumer machines and electronic...
