Method and system for realizing security data transmission in non-structured compensating data business

Abstract

The current invention discloses a method and system that can implement data safety transferring in USSD operation. The operation order is managed by USSD node, make interaction between the orders of USSD node and mobile phones, for the order of which data need to encrypt, then combining STK technology adopt cipher text short message to complete the order interaction between the USSD node and mobile phone SIM card, the make the obtaining cipher text deciphering and storing, after all the data of this operation has obtained ,USSD node form the full cipher text message according to corresponding application protocol, send it to corresponding server to decipher and handle. The current invention fully utilizes USSD technology to release the time-delaying problem of short message, meanwhile implement the data ciphering and safety checking, can be applied in mobile electronic business, mobile electronic government affair and so on USSD service.

Description

technical field [0001] The invention relates to a USSD service in the field of digital mobile communication, in particular to a method and a system for implementing service menu management and data transmission by applying the USSD technology. Background technique [0002] In order to attract new users, the focus of competition in the mobile field has gradually shifted from network coverage to service competition. At present, mobile communication companies have introduced a mobile intelligent network that provides prepaid services, a short message platform (SMS) that provides mobile banking, Yitong, and information on demand (including SIM cards) services, a WAP platform that provides mobile Internet services, and USSD services. . [0003] USSD (Unstructured Supplementary Service Data) is a new type of interactive data service based on the GSM network. It is a new service launched on the basis of the GSM SMS system technology. It can provide securities transactions and info...

AI Technical Summary

Problems solved by technology

[0011] However, during the USSD call in the above process, the mobile phone can only interact with the USSD node machine, but cannot perform data interaction with the SIM card (Subscriber Identify Module, Subscriber Identity Module)

The interaction between the mobile phone and the USSD node machine can only be transmitted in plaintext. When the SIM card is required to encrypt and decrypt key data and realize the transmission of ciphertext data (such as the transfer amount, withdrawal password, transfer account, etc.), simple The use of USSD technology can no longer meet the requirements, that is, data security cannot be guaranteed, but only menu management can be realized

Therefore, the data interaction mode that completely adopts USSD technology cannot meet the data services that require ciphertext transmission, such as mobile e-commerce, mobile e-government services, etc.
