Embodiment Construction

[0077] The technical solution of the present specification embodiment will be described in detail below with reference to the accompanying drawings.

[0078] The present specification is disclosed an offline bill generation method and apparatus, and the application scenario and inventive concept generated by the offline bill is described below, as follows:

[0079] In the case where the account generates a transaction when its device is in offline, you need to generate offline bills locally in the device and store the offline bill to the device. Subsequent, in the networking state, the offline bill generated by the device is in the offline state period, synchronizes to the corresponding server, so that the server is allocated to the target account based on the offline bill, update the balance. Among them, the account can be the account of the payee or the account of the payer.

[0080] Due to the device where the device is located offline, the offline bill is stored in the device,...

Abstract

The embodiment of the invention provides an offline bill generation method and device, and the method comprises the steps that a terminal device comprises a trusted execution environment (TEE) and a security element based on encryption hardware, and the terminal device obtains basic transaction information corresponding to the transaction and identity identification information of the target account in the TEE under the condition that the terminal device detects that a target account generates a transaction in an offline scene; the basic transaction information and the identity identification information are sent to a secure element; in the secure element, the basic transaction information and the identity information are signed by using a stored first private key to obtain a first signature; and in the TEE, the basic transaction information, the identity identification information and the first signature are combined, an offline bill corresponding to the transaction is generated, and the offline bill is stored.

Description

Technical field [0001] This specification relates to the field of electronic payment safety, and in particular, there is an offline bill generation method and apparatus. Background technique [0002] Offline payments are increasingly attached to and concern from all parties, in which offline payments are not required to pay, including single line payment and double offline payment. Single line refers to the payment of the payment, the payment is offline, and the double offline refers to the payment party and the payment party are offline. Unlike all bills in the electronic payment of online, all bills are generated in real time in the server, which is directly stored on the server, offline payment, first generated locally from the device where the device is located, and will be in the networked state of the device from the line. The stored bill is synchronized to the corresponding server. That is to say, the bill generated offline payment needs to be stored locally from the devic...
