Vehicle-mounted payment method and system based on vehicle-mounted SIM card

Abstract

The application provides a vehicle-mounted payment method and system based on a vehicle-mounted SIM card, which comprises the following steps: performing protocol analysis processing on a payment request message initiated by a vehicle-mounted terminal to generate a corresponding payment transaction element set, and performing reading and conversion processing on multi-security domain identity data built in the vehicle-mounted SIM card to generate a corresponding identity verification parameter set; performing security domain binding processing on the payment transaction element set and the identity verification parameter set based on payment protocol compliance to generate a corresponding transaction security context; generating a corresponding payment instruction execution link according to the transaction security context, wherein the payment instruction execution link internally contains a plurality of sequentially arranged security verification nodes; and internally issuing transaction execution parameters to the plurality of security verification nodes to complete verification flow conversion to generate a corresponding final payment instruction message. The application can greatly improve the efficiency of vehicle-mounted payment.
