Abstract

The invention discloses a mobile payment system and method based on a trusted execution environment, and relates to the technical field of mobile payment. According to the mobile payment system, a hardware environment module, a client terminal application module and a trusted application module are connected in a pairwise mode. The mobile payment method includes the steps that a virtual card number of the client terminal application module is transmitted to the trusted application module to be processed, then the virtual card number is returned to the client terminal application module, and afterwards the virtual card number is transmitted to a POS front end for conducting verification and consumption. The mobile payment system and method based on the trusted execution environment are suitable for near field mobile payment equipment, and the security is high.

Description

technical field [0001] The present invention relates to the technical field of mobile payment, in particular to a mobile payment system and method based on Trusted Execution Environment (TEE, Trusted Execution Environment). Background technique [0002] With the rapid development of mobile Internet and mobile finance, mobile payment schemes emerge in endlessly, including near-field payment, remote payment, QR code payment, etc. Some mobile payment schemes need to bind bank cards, and some mobile payment schemes are controlled by SE (Security Element), SIM, SD and other security chips are completed, and some are completed by mobile phones.
