Abstract

The invention discloses an authentication method of a telecommunication intelligent card and a terminal thereof which relate to the data security field. The method and the terminal can prevent a wireless business phone and the telecommunication card of a wireless public phone from embezzling by the unwarranted terminal, and avoid telephone expenses running off. The method includes steps as follows: preplacing a same encryption arithmetic and an authentication key ensuring same on the telecommunication intelligent card and an embedded type safe module ESAM, the embedded type safe module locates in the terminal; placing the network authentication user authentication information as a false information before executing the network authentication; processing authentication through the terminal as a transmitting channel between the telecommunication intelligent card and ESAM by using the encrypting arithmetic and the authentication key; if passing through authentication, placing the network authentication user authentication information as a true information of the telecommunication intelligent card; executing network authentication according with the network authentication user authentication information.

Description

technical field [0001] The invention relates to the field of data security, in particular to an authentication method and a terminal for a telecommunication smart card. Background technique [0002] In order to cooperate with the village-to-village project and develop customers in rural areas, China Mobile and China Unicom have promoted wireless business phones and wireless public phones across the country. They are charged according to the fixed-line tariff standard, because this charging standard is cheaper than ordinary mobile phones, and The wireless network can only authenticate and authenticate telecom smart cards, leading some people to use the smart cards of wireless business phones and wireless public phones in mobile terminals such as mobile phones by stealing cards or combining cards, resulting in A large number of phone bills were lost, which interfered with the normal tariff policy. [0003] In view of the above-mentioned card theft and card combination phenome...
