Embodiment 1

[0075] This embodiment provides a working method of PC / SC driver library in IOS equipment, such as figure 1 shown, including:

[0076] Step 101: start, the PC / SC driver library obtains the external device information in the IOS system, and obtains the preset card reader device information in the application program;

[0077] In this embodiment, the PC / SC driver library obtains the external device information in the IOS system, specifically including:

[0078] The PC / SC driver library obtains the first singleton object in the ExternalAccessory.framework framework in the IOS system, and obtains all the external device information in the IOS system through the first instance method of the first singleton object, and the obtained external device information to enumerate;

[0079] Among them, the first singleton object is: EAAccessoryManager; the first instance method is: connectedAccessories. External device information includes: external device name, manufacturer information, ...

Embodiment 2

[0184] This embodiment provides a method for querying the state of the card slot, specifically in Embodiment 1, while the PC / SC driver library judges whether the first notification has been registered with the IOS system registration center, it also includes: PC / SC driver library startup Query the status thread of the card slot, and perform the operation of querying the status of the card slot;

[0185] Specific operations such as image 3 shown, including:

[0186] Step 201: PC / SC drive library initialization card slot status identification;

[0187] In this embodiment, the PC / SC driver library initializes the slot status identifier to 0x00;

[0188] Step 202: The PC / SC driver library judges whether there is an external device that matches the preset card reader accessory protocol in the application program and is connected to the IOS system according to the accessory protocol information of the external device and the accessory protocol information of the card reader, and if...

Embodiment 3

[0218] This embodiment provides a method for querying the state of the card slot, specifically in Embodiment 1, while the PC / SC driver library judges whether the first notification has been registered with the IOS system registration center, it also includes: PC / SC driver library startup Query the status thread of the card slot, and perform the operation of querying the status of the card slot in a loop until the PC / SC driver library releases the resource manager context handle and ends;

[0219] The operation of querying the status of the card slot includes:

[0220] Step 301-1: PC / SC driver library initializes the card slot status identification;

[0221] In this embodiment, the PC / SC driver library initializes the slot status identifier to 0x00;

[0222] Step 301-2: The PC / SC driver library judges whether there is an external device matching the card reader accessory protocol registered by the application program according to the accessory protocol information of...

Abstract

The invention provides a working method of a PC / SC driving base in an IOS device, and belongs to the field of information safety. The method comprises the following steps: the PC / SC driving base obtains an external device fitting protocol information from the IOS system, and obtains card reader fitting protocol information from an application procedure, and obtains an external device connected with the IOS system; a communication channel between the external device and the IOS system is initialized so as to obtain a communication channel object; the external device information of the external device is stored, and a first notice is registered at an IOS registration center to judge if there is the external device connected with the IOS system; if it is, an instruct interface used for visiting the external device and provided by dispatching the PC / SC driving base so as to communicate with the external device; otherwise, the plug-in or plug-out of the external device can be detected through the first notice. By adopting the working method of the PC / SC driving base in the IOS device, the communication between the IOS system and the external device can be realized by means of the PC / SC driving base.

Description

technical field [0001] The invention relates to the field of information security, in particular to a working method of a PC / SC driver library in an IOS device. Background technique [0002] PC / SC interface is a standard user interface based on WINDOWS platform, which provides an integrated environment from personal computer (Personal Computer) to smart card (SmartCard), allowing multiple applications to share the resource manager of the same smart card in the system; [0003] With the wide application of Apple devices, the combination of smart cards and Apple devices has also attracted the attention of users. Those skilled in the art find that, at present, IOS, as the operating system of the Apple device, does not support the PC / SC interface. Contents of the invention [0004] In order to solve the defects in the prior art, the present invention proposes a working method of a PC / SC driver library in an IOS device, so that the PC / SC interface can be applied in the IOS sys...
