Abstract

The invention discloses a method and a system for updating a key. The method comprises the following steps that: a card issuer management platform receives a main security domain updating request of an intelligent card sent from a service terminal in a pre-determined data format and selects the main security domain of the intelligent card via the service terminal so as to establish a safety passage with the intelligent card; and the card issuer management platform and the intelligent card perform key updating operation on the selected main security domain via the safety passage. By using the technical scheme, the method can realize updating of the main security domain key of the intelligent card via the service terminal in a safe way.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a key update 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 related applications of electronic payment. Moreover, the application of mobile phones in the field of electronic payment will further expand the scope of use of mobile phones and bring more benefits to people's lives. It is convenient and has broad application prospects. [0003] In related technologies, in order to realize mobile electronic...
