Problems solved by technology

[0005] However, this smart card only stores the operating system and the application program separately on the hardware device, and the storage needs to be stored according to the physical address of the memory, which not only brings trouble to the development of the developer, but also stores different data in the second storage area 32. Application programs can still visit each other, and a malicious third party can still maliciously modify other application programs stored in the second storage area 32, which still brings security risks to the open application of smart cards

Embodiment Construction

[0021] The smart card using the smart card open application development method of the present invention includes hardware devices, and these hardware devices include a central processing unit, a memory, a timer, a counter, a universal asynchronous transceiver, a memory management unit, etc., wherein the central processing unit can read or rewrite the stored The data in the memory, the memory includes random access memory RAM, read-only memory ROM, electrically erasable programmable read-only memory EEPROM, etc., which are consistent with existing smart cards.

[0022] The memory of the smart card stores the driver program for driving the hardware device, the operating system of the smart card, the file system management program and the application program, and these programs and files are divided into different levels and stored in the memory. Referring to FIG. 2 , FIG. 2 is a schematic structural diagram of a smart card layer using the smart card open application development m...

Abstract

The invention provides a development method for open application of a smart card, comprising the following steps of: dividing the smart card into a hardware platform layer, a platform-supporting layer, an operating system layer and an application layer, dividing the virtual space of the smart card into a plurality of privilege data packages and common data packages, setting the access right for the privilege data packages and the common data packages, and storing the hardware driving program of the platform-supporting layer and the operating system of the operating system layer into the privilege data packages. The invention can make the smart card safely open to the open application system of a third party, and allow the third part (such as a bank), to apply the language which can be compiled into the machine instruction to develop the application program of the smart card and improve the running speed of the smart card.

Description

technical field [0001] The invention relates to a development method of an open application of a smart card, in particular to a development method of an open application of a smart card which can be downloaded by a third party to the smart card. Background technique [0002] Smart cards have the advantages of high security performance, small size, and large storage capacity, and have been widely used in mobile communications, e-commerce and other fields. An existing smart card is installed with a smart card operating system (COS) and application programs running on the operating system. Some existing smart card applications are not developed by the developer of the smart card operating system, but by a third party, such as a bank, to enable the smart card to achieve certain specific functions. Some existing application programs are developed using languages ​​that can be compiled into machine instructions, such as C language, and then compiled into instructions that can be ...
