Problems solved by technology

[0005] Using the current scheme of using the card writing component to write the card, on the one hand, the maintenance cost of the card writing component is relatively high. Since the card writing component is highly dependent on the system software and hardware environment, when the environment used by the card writing component changes, Mobile operators need to convene SIM card suppliers to update the card writing components and compile different versions of the card writing components to adapt to the new application environment; on the other hand, there is no security protection for the card writing data during transmission. The APDU command generated by the card writing component is writing card data in clear text, which is very easy to be cracked and copied, which is not conducive to the security protection of the card manufacturers for their cards, but also causes potential harm to the operation of the operator. If the card is Duplication will also cause losses to the rights and interests of users

Embodiment 1

[0048] The embodiment of the present invention provides a smart card writing method, such as figure 1 As shown, the method includes:

[0049] Step S11, analyzing the card information of the smart card according to the acquired identification of the smart card;

[0050] When a smart card needs to be written, the card writing data organization device on the server needs to obtain the identification of the smart card to be written. The identification can be the serial number of the smart card, and the serial number is an identification that can uniquely identify a smart card. Information such as the manufacturer, version, and batch of the smart card can be obtained, that is, the card information includes information such as smart card supplier information, smart card batch information, and smart card version information. Card writing data is personalized data configured according to specific services. Taking the mobile operator’s card writing operation as an example, the persona...

Embodiment 2

[0073] The embodiment of the present invention provides a smart card writing method, such as Figure 7 As shown, the method includes:

[0074] Step S101, sending an identification request to the smart card;

[0075] The card writing data organization device sends an identification request to the smart card to obtain the identification of the smart card. The identification can be the serial number of the smart card. The serial number is an identification that can uniquely identify a smart card. According to the identification, the manufacturer and version of the smart card can be obtained , batch and other information.

[0076] Step S102, receiving the identification of the smart card returned by the card writing data organizing device;

[0077] The card writing data organizing device sends the smart card identification to the card writing data organizing device according to the identification request.

[0078] Steps S101 and S102 are the process of obtaining the identificat...

Abstract

The invention discloses an intelligent card and a card writing method, equipment and a system thereof, relating to the field of intelligent cards, and aiming to enhance the information safety in the card writing process of the intelligent card. The card writing method of the intelligent card comprises the following steps: analyzing the card information of the intelligent card according to an acquired mark of the intelligent card; acquiring an encryption key matching with the intelligent card according to the card information; encrypting the acquired card writing data of the intelligent card to a cipher text through the encryption key; and transmitting the cipher text so that the intelligent card deciphers the cipher text to a plain text through the encryption key for card writing operation. The invention is applied to the card writing operation of the intelligent card.

Description

technical field [0001] The invention relates to the field of smart cards, in particular to a smart card and a card writing method, device and system thereof. Background technique [0002] At present, there are many manufacturers providing SIM (Subscriber Identity Module, customer identification module) cards for mobile operators. In the process of writing data into SIM cards, mobile operators must use the card writing components provided by each SIM card manufacturer. Generate a corresponding application protocol data unit (Application Protocol Data Unit, APDU for short) instruction, and perform a card writing operation. Since the card writing component is closely related to the system hardware, operating system, etc., when the environment for writing the card changes, the mobile operator needs each SIM card manufacturer to provide the card writing component under the new environment. [0003] The APDU command generated by the card writing component contains part of the imp...
