Problems solved by technology

But for the logical encryption card, it cannot process the APDU command itself and does not apply the CCID protocol, so the method of directly accessing the logical encryption card by issuing the APDU command through the CCID protocol channel cannot be realized
[0005] In the prior art, if you want to operate the logical encryption card, you need to purchase a specially developed card reader on the market that does not integrate the CCID protocol to access the logical encryption card, which brings inconvenience to the operation of the logical encryption card.

Embodiment 1

[0060] In order to enable the card reader to use standard APDU instructions to directly operate the logical encryption card inserted into the card reader, this embodiment provides a method for operating a smart card, wherein the card reader in this embodiment integrates the CCID protocol, and The mapping relationship between the standard APDU command and the logical encryption card operation command is pre-stored; and the mapping relationship between the logical encryption card operation request and the standard APDU command is also pre-stored in the computer connected to the card reader. see figure 1 , the method includes:

[0061] Step 101: Insert the smart card into the slot of the card reader, and then establish a connection between the card reader and the computer; while establishing the connection between the card reader and the computer, the card reader receives the smart card power-on command issued by the computer;

[0062] Step 102: the card reader judges the type o...

Embodiment 2

[0089] In order to enable the card reader to use standard APDU instructions to directly operate the logical encryption card inserted into the card reader, this embodiment provides a method for operating a smart card, wherein the card reader in this embodiment integrates the CCID protocol; The mapping relationship between the logic encryption card operation request and the logic encryption card operation instruction is stored in advance in the computer to which the card reader is connected. see figure 2 , the method includes:

[0090] Step 201: Insert the smart card into the slot of the card reader, and then establish a connection between the card reader and the computer; while establishing the connection between the card reader and the computer, the card reader receives the smart card power-on command issued by the computer;

[0091] Step 202: the card reader judges the type of the smart card inserted into its slot, and establishes a connection with the smart card;

Abstract

The invention discloses an operation method of a smart card and a system thereof and pertains to the applicable field of smart cards. The method comprises the steps as follows: the smart card is inserted in a slot of a card reader which is connected to a computer; the card reader detects the type of the smart card; when the smart card is a logistic encrypted card, the computer accepts an operation request sent by a user on the logistic encrypted card and maps the operation request on the logistic encrypted card as an APDU command which is sent to the card reader through CCID protocol; the card reader maps the received APDU command as a logistic encrypted card operation command which is sent to the smart card to carry out operation on the smart card; and when the smart card is a CPU card, the computer sends the APDU command through the CCID protocol to the card reader; and the card reader sends the received ADPU command to the smart card to carry out operation on the smart card. The method and the system solve the problem that the existing card reader operating the logistic encrypted card cannot be accessed through the APDU command.

Description

technical field [0001] The invention relates to the field of application of smart cards, in particular to an operation method and system of 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, which enables mutual communication between smart card reading and writing devices and hosts or other embedded hosts become possible. The CCID standard specifies that a CCID device is a chip / smart card interface device. The CCID device is connected to the host or other embedded hosts through the USB interface to perform data communication conforming to the CCID standard; at the same time, the CCID device communicates with the smart card through the interface conforming to the 7816 standard protocol. Many operating systems (such as versions above Windows 2000, Linux, etc.) provide and support CCID drivers, so that equipment...
