Smart card and terminal capable of realizing machine card security authentication

Abstract

A smart card and a terminal capable of realizing machine card security authentication are disclosed; the card comprises a first interaction module which is used for being interacted with the terminal, a card-terminal interaction authentication module, a card locking module, an authentication key acquisition module, an algorithm package module and a data packet processing module; the authentication key acquisition module is used for instructing the card-terminal interaction authentication module to conduct machine card authorization when a received terminal mark after each startup is consistent with a formally stored terminal mark; when not consistent, the received terminal mark is temporarily stored, and the content of a key updating request message which is transmitted to a server is generated and then transmitted to the data packet processing module for package; when the decrypted key updating message content is received, an authentication key in the content is acquired and then used for updating the authentication key data which is stored in the card-terminal interaction authentication module, later the temporarily stored terminal mark is used for updating the terminal mark which is formally stored in the card, and finally the terminal is instructed to be restarted when the updating is successful. The invention can achieve security authentication.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a smart card and a terminal capable of realizing machine-card security authentication. Background technique [0002] With the development of diversified competition in mobile services, operators need to launch low-rate services in which dedicated terminals and dedicated cards are used in conjunction with each other. They need to sell terminals at extremely low prices or give terminals away for free or return them through mobile phone numbers through the use of dedicated cards. This requires technical means to achieve mutual authentication and binding between dedicated terminals and dedicated cards, to ensure that dedicated subscriber identification modules can only be used for dedicated terminals, not for ordinary mobile terminals, and / or dedicated terminals can only be used for dedicated users The identification module cannot use common user identification.

AI Technical Summary

Problems solved by technology

[0005] (2) If an irregular random number PIN is used, the user terminal will be damaged, and the card will not be able to use the new terminal

[0007] (4) It cannot meet the business needs of separate sales of terminals and cards, and cannot be used for agent channel sales

[0008] Use special-shaped card and mobile phone IMEI lock: special-shaped card and mobile phone IMEI lock method, because illegal card stickers can easily imitate the terminal interface to define the opposite sex interface or forge the IMEI, so the security of the scheme is also poor

[0009] The random number authentication method is used: the random number authentication method has more parties who know the key, and it is easy to leak the key, and after the key leak occurs, it is impossible to determine the party responsible for the leak, the operator cannot identify the illegal patch user, and cannot prohibit illegal continued use of the card
