Problems solved by technology

The temporary USIM card order data obtained by card manufacturers is not generated from one system, which leads to data consistency problems. In addition, in terms of authentication data, if K is non-enhanced K generated by each card manufacturer, it is very difficult to It is easy to be cracked, and it is difficult to guarantee the security of authentication data

Embodiment Construction

[0010] The present invention adopts a new type of temporary USIM card preset data generation method to replace the traditional USIM card data generation method, and generates all data such as input element number segment information, personalized data, authentication data, and encryption and decryption keys at one time , and encrypt the corresponding authentication data and encryption and decryption keys in the above data during the above data generation process to ensure the data security of the above data during the generation, storage and transmission process.

[0011] The operator sends the data generated by the present invention to each card manufacturer for card production. Since the data in the temporary USIM card in the present invention is generated at one time, various different production processes that occur in the prior art are avoided. Card manufacturers need to carry out secondary development of data processing software after receiving the order. This not onl...

Abstract

The invention relates to a preset data generation method for a temporary USIM (Universal Subscriber Identity Module) card. The method comprises the following steps that personalized data is generated, authentication data is generated, a temporary number list is selected, the validity period of preset data of the temporary USIM card is selected, and background software generates the preset data of the temporary USIM card according to the generated personalized data and authentication data and the selected temporary number list and validity period. A user can store the generated temporary USIM card in a text format.

Description

technical field [0001] The invention relates to a method for generating chip card data, in particular to a method for generating temporary USIM card preset data. Background technique [0002] The rapid development of mobile communication technology has greatly facilitated people's lives. With the development of mobile communication technology, the chip card that stores user information must also be updated, that is, the matching chip card needs to be replaced under the new network standard. , For example, the chip card matched with 4G mobile communication is a temporary USIM card (Universal Subscriber Identity Module Universal Subscriber Identity Module), and data needs to be written in the temporary USIM card before use. Temporary USIM card data includes two parts, one part is the content generated by the data management center of each province, these generated contents include empty card serial number 2F02, ICCID, IMSI, PIN1, PIN2, PUK1, PUK2, SMSP, etc. The manu...
