Embodiment 1
[0060] This embodiment 1 provides a method for simulating smart card information interaction using file I / O streams. Specifically, by creating two information interaction files to simulate smart card information interaction, in this embodiment 1, set the created two information interaction The files are pctoic.ads file and ictopc.ads file respectively. The specific implementation steps are as follows:
[0061] Step 101: Start the chip development software, load the COS image into the operating environment of the chip development software, and start the soft card;
[0062] In this embodiment, the COS running on the COS image and the real smart card are different except for the I / O interface in the exchange data layer, and the logic implementation layer is the same;
[0063] Wherein, the soft card refers to a simulated smart card.
[0064] Step 102: the client establishes a connection with the soft card;
[0065] Step 103: The soft card is powered on, and the COS runs on the ...
Embodiment 2
[0149] This embodiment 2 also provides a method for simulating smart card information interaction using file I / O streams. Specifically, in this embodiment 2, only one information interaction file is created to simulate smart card information interaction, that is, only one file is used to To simulate downlink data transmission and uplink data transmission, the information interaction file is set as data.ads file in Embodiment 2. The specific implementation steps are as follows:
[0150] Step 201: Start the chip development software, load the COS image into the operating environment of the chip development software, and start the soft card;
[0151] In this embodiment, the COS running on the COS image and the real smart card are different except for the I / O interface in the exchange data layer, and the logic implementation layer is the same;
[0152] Wherein, the soft card refers to a simulated smart card.
[0153] Step 202: the client establishes a connection with the soft ca...

Abstract
The invention discloses a method for simulating interface interaction of a smart card, which comprises the following steps of: starting a soft card which is used for simulating the smart card on a personal computer (PC) platform; allowing the soft card to operate a chip operation system (COS); and simulating the information interaction with a client when the soft card operates the COS by using aninput / output (IO) flow of an information interaction file. In the invention, the data interaction between the smart card and the client is simulated by the simulation soft card of the PC platform andthe IO flow of the file, so the problems caused by resource shortage of a development board is solved and the development efficiency of the large-size COS is greatly improved.
Description
technical field [0001] The invention relates to the field of smart cards, in particular to a method for simulating smart card information interaction by using file I / O streams. Background technique [0002] A smart card (Smart Card, abbreviated as SC) is embedded with a microchip, and the smart card operating system is usually called a chip operating system COS (Chip Operating System), which is generally developed around the characteristics of the smart card it serves. Because it is inevitably affected by the performance and memory capacity of the microprocessor chip in the smart card, COS is largely different from the operating systems (such as DOS, UNIX, etc.) on microcomputers that we can usually see. [0003] First, COS is a dedicated system rather than a general-purpose system. That is: generally, a COS can only be applied to a certain (or some)) smart cards, and the COSs in different cards are generally different. Although most of the functions actually completed by ...
