Abstract

The invention provides a smart card slave security domain key updating method and an electronic payment system. The smart card slave security domain key updating method comprises the steps of triggering an application downloading request by a user, and transmitting the application downloading request to an application provider management platform; transmitting security domain establishing request information by the application provider management platform to a card issuer management platform; transmitting an initial key of the slave security domain by the card issuer management platform to a smart card main security domain by means of the application provider management platform and an application provider service terminal, and initializing the slave security domain by the smart card main security domain according to the initial key of the slave security domain; and transferring a control right of the slave security domain to the application provider management platform by the card issuer management platform, and updating the initial key of the smart card slave security domain by the application provider management platform. The smart card slave security domain key updating method and the electronic payment system realize transmission of a new slave security domain key to the smart card slave security domain through a safe communication channel, thereby updating the slave security domain key.

Description

[0001] This case is a divisional application of patent application 200810177014.5. The original application date is November 10, 2008, and the application number is 200810177014.5. The invention name is a method, system and mobile terminal for updating and distributing keys from the security domain of smart cards. technical field [0002] The present invention relates to a mobile terminal electronic payment technology based on NFC (Near Field Communication, near field communication technology), in particular, to a method for updating a key of a smart card from a security domain and an electronic payment system. Background technique [0003] Near Field Communication (NFC) is a short-range wireless communication technology working at 13.56MHz, which evolved from the fusion of RFID technology and interconnection technology. After integrating NFC technology, mobile communication terminals such as mobile phones can simulate non-contact IC cards for related applications of electron...
