Embodiment 1

[0055] Such as figure 1 As shown, the embodiment of the present invention provides a data transmission method, specifically as follows:

[0056] 101. The smart card server establishes a card application tool protocol (Card Application Tookit_Transfer Protocol, CAT_TP) data link with the Java smart card.

[0057] The smart card server sends a data short message, which contains two push PUSH commands encapsulated by the Secure Channel Protocol (SecureChannel Protocol, SCP) 80, namely PUSH[for Bearer Independent Protocol (BIP)] command and PUSH[ for CAT_TP] instruction. After the Java smart card receives the sent data message, the Java smart card first processes the PUSH [for BIP] command, specifically, the Java smart card sends an Open Channel command to the terminal where the Java smart card is located, and then the terminal where the Java smart card is located opens the Java smart card and The BIP channel between the terminals where the Java smart card is located. After the...

Embodiment 2

[0105] Such as image 3 As shown, the embodiment of the present invention provides a device 30 for data transmission, and the device 30 includes: a link establishment module 301 and a sending module 302 . Specifically, the device 30 may be a smart card server, specifically, a remote server managed and controlled by an operator.

[0106] Establish link module 301, for establishing CAT_TP data link with Java smart card;

[0107] The sending module 302 is used to send the stored data STORE DATA instruction adopting double-layer encapsulation to the Java smart card on the CAT_TP data link, wherein the double-layer encapsulation includes the safe channel protocol SCP02 and SCP80, and the STORE DATA instruction adopting the double-layer encapsulation carries personalization data.

[0108] Further, such as Figure 4 As shown, the embodiment of the present invention can also provide another data transmission device 40 . Wherein, the data transmission device 40 further includes: a ...

Embodiment 3

[0117] Such as Figure 5 As shown, the embodiment of the present invention provides a system 50 for data transmission, and the system 50 includes: a smart card server 501 , a Java smart card 502 , and a third-party server 503 .

[0118] The smart card server 501 is used to establish a CAT_TP data link with the Java smart card 502; on the CAT_TP data link, the stored data STORE DATA instruction adopting double-layer encapsulation is sent to the Java smart card, wherein the double-layer encapsulation includes safe channel protocols SCP02 and SCP80, and adopts double-layer encapsulation. The encapsulated STORE DATA command carries personalized data; receive the STORE DATA command encapsulated in SCP02 sent by the third-party server 503, and use SCP80 to continue encapsulating the STORE DATA command encapsulated in SCP02 to obtain a double-packaged STORE DATA command.

[0119] The Java smart card 502 is configured to receive the establishment of a CAT_TP data link with the smart c...

Abstract

The invention discloses a data transmission method and device, relates to the technical field of communication networks, and is used to solve the problem of low transmission efficiency when a smart card server and a Java smart card perform OTA data interaction. In the embodiment of the present invention, the card application tool protocol CAT_TP data link is established through the smart card server and the Java smart card; the smart card server sends the stored data STORE DATA instruction using double-layer encapsulation to the Java smart card on the CAT_TP data link, wherein the double-layer encapsulation includes the secure channel protocol SCP02 And SCP80, the personalized data is carried in the STORE DATA instruction with double-layer encapsulation. The solutions provided by the embodiments of the present invention are suitable for use when transmitting OTA data.

Description

technical field [0001] The present invention relates to the technical field of communication networks, in particular to a data transmission method and device. Background technique [0002] At present, there are mainly three ways for the data source of Java smart card. The first way is to preset the Java smart card. Generally, the data of the Java smart card is preset when the Java smart card leaves the factory; , POS) terminal to download the data of the Java smart card; the third way is to download the data of the Java smart card by using Over The Air (OTA) technology. [0003] When sending OTA data information to the Java smart card, the second and third methods are generally adopted. Among them, when the Java smart card needs to receive large-capacity OTA data (such as installation data package, update data package, etc.), the second method can be used to download the OTA data from the POS terminal. When the third-party server needs to send small-capacity OTA data (such...
