Problems solved by technology

However, there is no security authentication mechanism for the data channel established between the smart card and the entity outside the card, so the entity outside the card can access the smart card at will, which will constitute an attack on the smart card, thereby arbitrarily obtaining sensitive information on the smart card (user identity information, bank card information, bank account balance, etc.), modify the data on the smart card, etc.

Embodiment 1

[0071] This embodiment provides a method for establishing a data channel, which is applied to an entity outside the card, and includes the following steps:

[0072] Obtain the security authentication information of the application data channel from the smart card management platform;

[0073] sending an authentication registration message carrying the security authentication information to the smart card device;

[0074] And after the smart card device successfully verifies the security authentication information, establishes a data channel with the smart card.

[0075] Wherein, the security authentication information obtained from the smart card management platform for the application data channel is specifically:

[0076] Sending a data channel registration application carrying corresponding application-related information to the smart card management platform;

[0077] Receive the security authentication information of the corresponding application sent by the smart card ...

Embodiment 2

[0126] In order to implement the method of Embodiment 1, this embodiment provides an off-card entity, such as image 3 As shown, the off-card entity includes: an obtaining unit 31, a first sending unit 32 and a data channel establishing unit 33; wherein,

[0127] The obtaining unit 31 is configured to obtain the security authentication information of the application data channel from the smart card management platform;

[0128] The first sending unit 32 is configured to send an authentication registration message carrying the security authentication information to the smart card device;

[0129] The data channel establishing unit 33 is configured to establish a data channel with the smart card after the smart card device successfully verifies the security authentication information.

[0130] Wherein, the obtaining unit 31 may further include: a first sending module and a first receiving module; wherein,

[0131] The first sending module is configured to send a data channel r...

Embodiment 3

[0182] The system for establishing a data channel in this embodiment, such as Figure 7 As shown, it includes a smart card management platform 71, an off-card entity 72 and a smart card 73; wherein,

[0183] The smart card management platform 71 is mainly responsible for generating a signature or token (Token) of the application software according to the application software information, and may include a data channel key or certificate storage module 711 (the function of which is equivalent to the function of the storage module in the second embodiment) and a data channel. The security module 712 (its function is equivalent to the sum of the functions of the second receiving unit, the second transmitting unit and the data channel security module in the second embodiment). Here, the data channel key or certificate storage module 711 is used to store the key or certificate of the data channel; the data channel security module 712 is used to generate the signature or Token of th...

Abstract

The invention discloses a method for building a data channel. The method comprises an off-card entity obtains security authentication information for applying the data channel from an intelligent card management platform; the off-card entity sends an authentication registering message carrying the security authentication information to the intelligent card management platform; and after the intelligent card management platform verifies the security authentication information successfully, the intelligent card management platform builds the data channel with the off-card entity. The invention also discloses the off-card entity, the intelligent card management platform, an intelligent card device and a system for building the data channel.

Description

technical field [0001] The invention relates to the field of data services, in particular to a method, a system and related equipment for establishing a data channel. Background technique [0002] With the popularization of mobile e-commerce, the data stored in smart cards is becoming more and more important. Smart cards can currently store sensitive information such as user identity information, bank card account information, and bank card account balances, so the security of smart cards is more important. [0003] At present, smart card products support entities outside the card to access through various physical connection forms such as contactless card readers, data lines (contact type), and Bluetooth, and to exchange data with smart cards. [0004] The security of the smart card depends on the smart card hardware device on the one hand, and on the data channel security mechanism between the smart card and the entity outside the card on the other hand. [0005] like f...
