Card application using method, device and application terminal in chip security domain

Abstract

The invention relates to a method and apparatus for utilizing card applications in a chip security domain. The method comprises the following steps: S1, according to a card application access capability request of an application terminal, obtaining available card application list from a trusted service management platform; S2, based on the card application list, applying for authorization of application of a digital certificate from a security authentication center; S3, establishing a binding relation between the digital certificate and the available card application list; S4, issuing the digital certificate and an SDK packet packaged with an APDU instruction of each card application to the application terminal; and S5, according to the application terminal, when the card applications need to be used, scheduling the digital certificate issued by SDK packet for authentication, and returning to the available card application list. The invention further relates to an application terminal, and a method for an application terminal to use card applications in a chip security domain. According to the invention, the threshold for the application terminal to use the card applications in the chip security domain can be mitigated, the card application promotion capability of the application terminal is enhanced, and the utilization security, consistency, integrity and undeniability of the card applications are guaranteed.

Description

technical field [0001] The present invention relates to the field of data communication, more specifically, to a method, device and application terminal for card application in the chip security domain. Background technique [0002] As a short-range wireless communication technology, NFC (Near Field Communication) provides a more direct and safer on-site interaction solution. It allows non-contact point-to-point data transmission between electronic devices, enabling data exchange, access to content and services. With this technology, mobile phones with NFC functions are no longer just tools for making calls, sending text messages and surfing the Internet, but can also be loaded with various electronic card applications (such as bank cards, bus cards, membership cards, campus / business cards, etc.), Realize various business applications based on payment and non-payment. [0003] For the NFC mobile phone client, it uses the card application of the chip security domain (SE), m...

AI Technical Summary

Problems solved by technology

[0009] 1. Each card application has a different interface, and each card application must be developed according to the standards provided by the card application provider;

[0010] 2. The client access card application needs to be registered on the TSM platform, and lacks the ability to integrate multiple applications together;

[0012] To sum up, the external mobile phone client uses the chip security domain (SE) card application, technically, there is a lack of unified standard specification instructions for calling cards; from the management point of view, all new card applications need to be applied for; In terms of business, online authentication is required every time it is enabled, and it cannot be done during business use to reduce the interaction frequency of online authentication
