Embodiment

[0056] Referring to Fig. 3, the method of using the CCID command flow to realize the information interaction between the smart card and the host computer conforming to the ISO7816 protocol standard, the specific steps are as follows:

[0057] Step 101: Power on the CCID device, declare itself as a CCID device, declare BULK-OUT, BULK-IN and interrupt endpoints and establish a connection with the host;

[0058] Step 102: The host sends a power-on reset command to the smart card to power on, and the CCID device receives and analyzes the reset response, and saves the smart card protocol type flag;

[0059] Step 103: the CCID device receives a command flow conforming to the CCID standard;

[0060] Step 104: the CCID device parses the command stream conforming to the CCID standard, and splits the header of the command stream;

[0061] Step 105: the CCID device judges the meaning of the command stream that meets the CCID standard, if it is a data transmission command, then perform s...

Abstract

The invention relates to a method for communicating information between host and intelligent card, and a relative device, wherein in order to avoid the driving program of intelligent card reader / writer, to cause slow communication, the inventive method uses CCID command flow to quickly realize the information communication. And the invention also provides a relative device.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a method and device for information interaction between a host and a smart card. Background technique [0002] The CCID (USB Chip / Smart Card Interface Devices-USB chip smart card interface device) standard is a standard jointly formulated by several major international IT companies. It provides a smart card reading and writing device to communicate with the host or other embedded hosts. possible. The CCID standard stipulates that the CCID device is a chip / smart card interface device. The device is connected to the host or other embedded hosts through the USB interface to perform data communication in compliance with the CCID standard. At the same time, the device communicates with the smart card through an interface that conforms to the ISO7816 standard protocol. Microsoft provides and supports CCID drivers on its WINDOWS2000 and above operating systems, so that equipment manuf...
