Embodiment Construction

[0052] figure 1 It is a flow chart of Embodiment 1 of the access method of the smart card of the present invention, as figure 1 As shown, the method of this embodiment may include:

[0053] Step 101, the terminal detects the secure storage area of ​​the smart card, and if the detection finds that the secure storage area is in the unmounted state, then sends a mount request to the smart card; the secure storage area is invisible to the terminal in the unmounted state.

[0054] Specifically, the smart card in this embodiment is, for example, a large-capacity telecom smart card, including a traditional CPU card part and a large-capacity storage part (that is, a secure storage area). In the loading state, the smart card will not be automatically mounted after it is inserted into the terminal, and the safe storage area or visible drive letter of the smart card cannot be seen and accessed from the terminal side, but the available space is displayed as zero. When the terminal needs...

Abstract

The invention provides an access method, device and system for an intelligent card. The access method for the intelligent card comprises the steps that a terminal detects a secure storage region of the intelligent card, and if the terminal detects and is informed that the secure storage region is in the dismounting status, the terminal sends a mounting request to the intelligent card; the secure storage region is invisible in the dismounting status for the terminal; after the terminal successfully passes through the authentication process of the intelligent card, the terminal has access to the secure storage region; after the intelligent card conducts authentication on the mounting request, and the mounting request passes through the authentication of the intelligent card, the secure storage region is set to be in the mounting status, and the secure storage region is visible in the mounting status for the terminal. According to the access method, device and system for the intelligent card, the real-time mounting control over the secure storage region of the intelligent card is achieved, and safety of access of the intelligent card is improved.

Description

technical field [0001] The invention relates to communication technology, in particular to an access method, device and system of a smart card. Background technique [0002] The large-capacity telecom smart card expands the storage space on the basis of the traditional telecom smart card (such as the Subscriber Identity Module (SIM) card), that is, adds a large-capacity flash memory module (such as 2G ~ 16G), so that Allow users to store more data in it. [0003] The data saved by the user includes some private data that needs to be prohibited from being accessed by other applications. In the prior art, a data security processing unit is added inside the smart card to realize safe storage of data through identity authentication. Before reading and writing data operations on the card , the unit first performs the user identity authentication operation. When the authentication fails, the unit prohibits the terminal from performing any read and write data operations on the car...
