Embodiment 1

[0090] figure 1It shows a schematic structural diagram of a secure application download system provided in this embodiment. It can be seen from the figure that the system includes a security module provider SEI background server 120, an application provider SP background server 130, and a security The security module SE 111 provided by the module provider SEI; the SEI background server 120 is connected to the SP background server 130 through a network.

[0091] In this embodiment, the SP background server 130 includes an SP application installation file generating means 131 , an operation request sending means 132 , an APP generating means 133 and an APP issuing means 134 . The SEI background server 120 includes an SEI key generation device 122 , an SEI key management device 123 and an SEI encryption device 124 .

[0092] The SP application installation file generation device 131 is used to generate the application installation file of the application; the operation request s...

Embodiment 2

[0107] figure 2 It shows a schematic structural diagram of a secure application program downloading system provided in this embodiment. On the basis of Embodiment 1, the system further includes a mobile terminal device 110 with the security module SE111 securely. The SEI decryption key SK.SEI.SEC generated by the SEI background server 120 is loaded in the module SE 111 . in:

[0108] The mobile terminal device is configured to download from the application download platform a downloadable application program APP installation package corresponding to the supplier information of the security module SE installed in the mobile terminal device, and analyze the downloaded APP installation package , get the ciphertext of the application installation file;

[0109] The security module SE is used to decrypt the ciphertext of the application installation file by using the stored SEI decryption key SK.SEI.SEC to obtain the application installation file P, and execute the application i...

Embodiment 3

[0120] image 3 It shows a schematic structural diagram of a secure application download system provided in this embodiment. On the basis of Embodiment 1 or Embodiment 2 in this embodiment, the SP background server 130 sends the SEI background server 120 to the The application operation request also includes a personalization request for satisfying the personalized processing of the application provided by the application provider SP. Correspondingly, in the secure download system described in this embodiment, on the basis of Embodiment 1, the SEI background server 120 further includes a personalized request response script generator 121 .

[0121] The personalization request response script generator 121 is configured to generate a personalization request response script SE.SCRIPT.PERSON that satisfies the personalization request when the received application operation request includes the personalization request;

[0122] At this point, the SEI background server 120 sends t...

Abstract

The invention discloses a safety downloading system for an application program, and the system comprises a mobile terminal device, a safety module provider SEI background server, and an application provider SP background server, wherein the mobile terminal device is provided with a safety module SE provided by a safety module provider SEI. The SEI background server is in network connection with the SP background server. According to the invention, the system organizes scripts based on the offline interaction of the application provider SP and a safety module provider SEI, enables the scripts to be issued on an application downloading platform at the format of an APP, and enables the mobile terminal device to download all required scripts at a time and perform the installation operation, thereby improving the downloading success rate. Through the management and control of the offline scripts, the system removes the authority checking during the downloading of the scripts, improves the downloading efficiency, guarantees that only a corresponding SE can operate the application script successfully through employing the SEI for the encryption of the scripts, and meets the requirements of safety while giving consideration to the convenience.

Description

technical field [0001] The invention relates to the field of application program security management, in particular to an application program security download system. Background technique [0002] In the traditional OTA (Over The Air, download over the air) method, a TSM (Trusted Service Manager, trusted service management) system is usually used as a download carrier. The TSM system connects mobile phone manufacturers, service providers, and other institutions that control the security module SE on the mobile phone through the mobile phone network. The TSM system allows service providers to remotely control their own applications on the SE by operating the SE, such as the download of packages. , application installation and personalization. In these application scenarios, two TSM systems will be used, one is the security module provider SEI (Secure Element Issuers) TSM and the service provider SP (Service Providers) TSM. [0003] SEI TSM is responsible for managing the k...
