[0035] Functional Overview

[0036] At present, in related technologies, when the card issuer management platform is responsible for the transmission of key data, it can obtain the sent security domain key data, and may use the obtained key pair to perform operations from the security domain, which will affect the application provider's electronic Payment application security poses a threat, and for this potential security risk, the present invention proposes a technical solution for transmitting security domain key data through an OTA server, thereby effectively isolating the card issuer management platform and ensuring the security of key transmission.

[0037] The present invention will be described in detail below with reference to the accompanying drawings.

[0038] Such as figure 1 As shown, the mobile terminal electronic payment system according to the embodiment of the present invention is mainly composed of a card issuer management platform 1, an application provide...

Abstract

A method and a system for key distribution are provided. The system includes a card issuer management platform, an application provider management platform, an Over The Air (OTA) server and a smart card. The card issuer management platform includes a first notification module, a first receiving module, an import module, a first sending module. The application provider management platform includes a second receiving module, a selection module, a second notification module, a generation module and a second sending module. The method and the system can prevent the card issuer management platform from obtaining a key of a subordinate security domain.

Description

technical field [0001] The present invention relates to the communication field, and in particular, to a key distribution method and system. Background technique [0002] In related technologies, near field communication technology (Near Field Communication, referred to as NFC) is a short-range wireless communication technology working at 13.56MHz, which consists of radio frequency identification (Radio Frequency Identification, referred to as RFID) technology and interconnection Technological convergence evolved. After integrating NFC technology, mobile communication terminals such as mobile phones can simulate non-contact IC cards for electronic payment related applications; in addition, to implement this solution on mobile communication terminals, NFC analog front-end chips and NFC antennas need to be added to the terminals. And use a smart card that supports electronic payments. [0003] After more than ten years of development, IC cards, especially non-contact IC card...
