Embodiment Construction

[0020] The embodiment of the present invention provides a method for realizing multiple applications of smart cards. By establishing the mapping relationship among application codes, application files and instructions, multiple applications of Native smart cards can be realized. An application file corresponding to an application ensures the independence of each application.

[0021] The Native smart card in the embodiment of the present invention has various applications, for example, application A, application B, application C, application D, and application E. In this way, each application supports some commands, so that the corresponding relationship between applications and commands can be established on the Native smart card. In the embodiment of the present invention, the correspondence between applications and instructions may include: a first correspondence between applications and instructions, and / or a second correspondence between applications and instructions. Am...

Abstract

The invention discloses a method and a device for realizing multi-application of an intelligent card, aiming at solving the problem that the independence of different applications is difficult to guarantee when the Native intelligent card is used in multi-application in the prior art. In the applications of Native intelligent card, the method comprises carrying out legitimacy verification on the received current command under the current application according to the saved corresponding relation of the application and the command when the received current command is an application type command, and operating the application file corresponding to the current application through the current command when the verification is passed.

Description

technical field [0001] The invention relates to the technical field of smart cards, in particular to a method and device for realizing multiple applications of smart cards. Background technique [0002] Native smart cards that are widely used at present mostly use an on-chip operating system (COS, Chip Operating System) to control the safe use of the internal memory. A Native smart card generally supports an application, that is, the supported command conforms to a certain application specification, and a corresponding application file system is established on the card according to the application requirements, so that after the smart card receives the command, COS operates the corresponding application through the command files to implement specific functional applications. [0003] With the rapid development of smart card applications, the social affairs, commercial services, and consumption activities involved continue to increase. Due to the single application of Native...
