Embodiment 1

[0038] figure 1 It is a flow chart of the authentication method for improving the access security of the JavaCard shared interface of the present application. Such as figure 1 As shown, the client program sends a request (110) to obtain the SIO object (Shareable InterfaceObject, shared interface object) of the server-side program through the shared interface; the client program receives the judgment data (120) returned by the server-side program through the shared interface; response The judgment data returned by the server-side program is an SIO object, and the client-side program performs data authentication, and requests the server-side program to perform data authentication (130) through the shared interface; receives the authentication result returned by the server-side program through the shared interface, and judges whether the authentication is Success (140); in response to successful authentication, the client program requests to perform a data sharing operation, and...

Embodiment 2

[0050] This embodiment proposes an authentication system for improving the access security of the JavaCard shared interface, which is applicable to the authentication method for improving the access security of the JavaCard shared interface described in the first embodiment. image 3 It is a structural schematic diagram of the authentication system for improving the access security of the JavaCard shared interface of the present application. Such as image 3 As shown, the authentication system improving JavaCard shared interface access security includes: an acquisition module 31, which sends a request to obtain the SIO object of the server-side program through the shared interface; a first receiving module 32, which receives the judgment data returned by the server-side program through the shared interface; The data authentication module 33, in response to the judgment data returned by the server-side program is an SIO object, performs data authentication, and requests the ser...

Abstract

The application discloses an authentication method and an authentication system for improving the access security of a JavaCard shared interface, relates to the technical field of smart IC cards, and solves the technical problem of low security when Applets access data through a shared interface in the prior art. The authentication method of the present application includes: sending a request to obtain the SIO object of the server-side program through the shared interface; receiving the judgment data returned by the server-side program through the shared interface; and performing data authentication in response to the judgment data returned by the server-side program as an SIO object , and request the server-side program to perform data authentication through the sharing interface; receive the authentication result returned by the server-side program through the sharing interface; respond to the successful authentication, request to perform a data sharing operation, and send a data sharing request to the server-side program through the sharing interface; Receive the data result returned by the server-side program through the shared interface. This application is mainly used for shared data access.

Description

technical field [0001] The application relates to the technical field of smart IC cards, in particular to an authentication method and an authentication system for improving the access security of a JavaCard shared interface. Background technique [0002] According to the requirements of JCRE (Java Card Runtime Environment, the operating environment of Java smart card applications), there are firewall protection between each Applet (program) in JavaCard. If you need to share data between two Applets during the development process, you need to use the sharing interface mechanism provided by JCRE to realize related functions. At this time, it is necessary to create a Sever Applet (server-side program) as the visitor, and the Client Applet (client program) accesses the methods (functions) provided by the Sever Applet through the shared interface. [0003] The current security strategy suggested in JavaCard is that before the Client Applet calls the Sever Applet, the Sever Appl...
