Virtual SIM/USIM card security protection system

Abstract

The invention discloses a virtual SIM / USIM card security protection system, at least comprising an identity recognition module, a terminal unique recognition code obtaining module, a locking module, an unlocking module, an encryption analysis module, a communication module, an optimal card number distribution module and an access network information storage module. The identity recognition module is respectively connected with the terminal unique recognition code obtaining module, the locking module, the unlocking module, the encryption analysis module and the access network information storage module; the optimal card number distribution module is respectively connected with the encryption analysis module, the communication module and the access network information storage module. According to the invention, whether a terminal matches with a virtual SIM / USIM card connected to the terminal is verified by an identity verification module; if the terminal does not match with the virtual card, communication between the terminal and the virtual card is forbidden through the locking module; if the terminal matches with the virtual card, the terminal is allowed to use the virtual card through the unlocking module; therefore the virtual card is prevented from being embezzled; and the security of the virtual card is improved.

Description

technical field [0001] The invention relates to the field of virtual SIM cards, in particular to a virtual SIM / USIM card security protection system. Background technique [0002] At present, the Internet of Things and other application fields have gradually begun to use virtual SIM cards to replace physical SIM cards. However, the security of virtual SIM cards has become an important issue today. At present, security verification through fixed passwords is generally used, but this This method is prone to problems such as password disclosure, and its security is not high. [0003] In addition, because traditional devices generally use one SIM card for one machine, for data transmission terminals with dual cards and single standby, in fact, only one number or at most two numbers can be used for services, and it is necessary to change operators and different tariff cards. At the same time, the user also needs to manually switch the SIM card. Even if it is a dual-card dual-stan...

[0002] At present, the Internet of Things and other application fields have gradually begun to use virtual SIM cards to replace physical SIM cards. However, the security of virtual SIM cards has become an important issue today. At present, security verification through fixed passwords is generally used, but this This method is prone to problems such as password disclosure, and its security is not high

[0003] In addition, because traditional devices generally use one SIM card for one machine, for data transmission terminals with dual cards and single standby, in fact, only one number or at most two numbers can be used for services, and it is necessary to change operators and different tariff cards. At the same time, the user needs to manually switch the SIM card. Even if it is a dual-card dual-standby device, it can only artificially select the optimal communication card number for communication every time it communicates.
