When the subscriber identity module card management apparatus 100 provides 1.8V power to the SIM card, after the activation process is performed, an ATR is returned, which indicates that the SIM card supports 1.8V voltage operation, i.e., belongs to the class C card. When the subscriber identity module card management device 100 provides 3.3V power to the SIM card, after the activation process is performed, an ATR returns, which indicates that the SIM card supports 3.3V voltage operation, i.e., belongs to the class B card; after the card category is obtained, the information is stored in the image file.

Further, referring to fig. 4, the present invention also discloses a SIM card mirror apparatus, which is characterized by comprising:

a subscriber identity card management apparatus 100, wherein the subscriber identity card management apparatus 100 is provided with a plurality of card slots 110, and the card slots 110 are used for placing SIM cards;

the processor 200 is electrically connected with the user identity identification card management device 100;

a memory 300, wherein the memory 300 is electrically connected with the processor 200;

and a SIM card simulator 400, wherein the SIM card simulator 400 is electrically connected with the memory 300.

Further, the present invention also discloses a computer readable storage medium having stored thereon program instructions which when executed by the processor 200 implement a SIM card mirroring method.

On the other hand, referring to fig. 6, after the mirror image SIM is generated, the mirror image SIM card and the physical SIM card need to be authenticated for use, so that the embodiment of the invention also provides a SIM card remote authentication method and a device thereof, the SIM card remote authentication method operates on a SIM card remote authentication device, the SIM card remote authentication device comprises an identity card management device, a server and a cloud terminal, which are sequentially connected, the identity card management device is at least one, the identity card management device is provided with a plurality of SIM cards, and the cloud terminal is electrically connected with a base station, and the SIM card remote authentication method is characterized by comprising the following steps:

s10, the cloud terminal receives a first authentication request signal sent from a base station operator access network, wherein the first authentication request signal comprises a random number generated by a base station;

s20, the cloud terminal judges whether the SIM card requesting authentication in the first authentication request signal is a physical SIM card or a mirror image SIM card, if the SIM card requesting authentication is the mirror image SIM card currently used by the cloud terminal, the cloud terminal combines mirror image SIM card information and the first authentication request signal into a second authentication request signal, and forwards the second authentication request signal to the server;

s30, after receiving the second authentication request signal, the server extracts mirror image SIM card information, and positions the corresponding identity card management equipment and a physical SIM card based on the SIM card information reported when the identity card management equipment logs in;

s40, the server combines the Token code generated randomly with the second authentication request signal into a third authentication request signal, and forwards the third authentication request signal to the corresponding identification card management equipment;

s50, after receiving the third authentication request signal, the identification card management device extracts an authentication data packet and sends the authentication data packet to a corresponding physical SIM card.

Firstly, an operator access network generates a random number and sends the random number to cloud terminal equipment through a wireless signal; and after receiving the authentication request of the access network, the cloud terminal directly sends the authentication request to the physical SIM card for processing if the physical SIM card is currently used. If a SIM mirror card is currently in use, the authentication package is forwarded to the server. When the cloud terminal equipment sends an authentication packet to the server, the IMSI number of the currently used SIM mirror image card and the authentication packet are combined together according to defined protocol rules and sent to the server. After receiving the data packet containing the authentication packet, the server takes out the IMSI from the data, finds the identity card management device corresponding to the current IMSI according to the SIM card information reported by the identity card management device when logging in, and forwards the authentication packet to the identity card management device. In particular, when the server issues an authentication packet to the identification card management device, a random Token is generated at the same time, the Token is packaged into a data packet by the authentication packet sent by the cloud terminal and the IMSI of the SIM card. The data packet head comprises the information such as the whole packet length, the serial number and the like; the data packet tail comprises the verification of the whole data packet and is used for verifying the integrity of the packet by the receiving party. The identity identification card management device stores the position information of all the SIM cards managed by the identity identification card management device, and establishes the corresponding relation between the IMSI information of the SIM cards and the SIM card information. When the identification card management equipment receives the authentication packet forwarded by the server, the IMSI number is taken out from the data packet, the SIM card position is found according to the number, and the SIM card position is forwarded to the physical SIM card. Meanwhile, the identification card management equipment also stores Token information in the received data packet temporarily, and establishes a corresponding relation between the Token and the position of the SIM card.

Further, the SIM card remote authentication method further comprises the following steps:

s60, after receiving the authentication data packet, the physical SIM card generates a first authentication feedback signal based on a preset IMSI code, a secret key, a random number generated by an operator access network and a preset encryption algorithm, and sends the first authentication feedback signal to the identity card management equipment;

s70, after receiving the first authentication feedback signal, the identity identification card management equipment generates a second authentication feedback signal based on the current Token code and sends the second authentication feedback signal to the server;

s80, after receiving the second authentication feedback signal, the server forwards the second authentication signal to a cloud terminal requesting authentication;

and S90, after receiving the second authentication feedback signal, the cloud terminal checks the second authentication feedback signal and generates a third authentication feedback signal of an operator access network format, and sends the third authentication feedback signal to an applied base station.

The SIM card remote authentication method provided by the invention realizes the communication between the physical SIM card and the mirror image SIM card and the base station, and the communication between the mirror image SIM card and the physical SIM card.

Specifically, when the terminal device is accessing the operator network, or when the operator access network deems necessary, the access network issues authentication request information to the terminal. The terminal equipment needs to respond to the authentication request, otherwise, the access network considers that the terminal equipment has no legal authority, thereby rejecting the service. For the cloud terminal device, since the mirror SIM card is used, the authentication process is different from that of a general physical SIM card.

The cloud terminal equipment is connected to the server through the Internet, and the server distributes a SIM mirror image card for the cloud terminal. Likewise, the identification card managing device is also connected to the server through the Internet network. The identification card management device is responsible for generating mirrored SIM cards and managing all SIM cards inserted onto the device. When the identification card management device is connected to the server, the managed SIM card information is reported, and the generated mirror image SIM card is reported.

Further, in the step S20, the method further includes:

and if the SIM card requesting authentication is a physical SIM card, the cloud terminal forwards the first authentication request signal to the physical SIM card requested to be authenticated through the server and the identification card management equipment.

Further, in the step S20, the mirrored SIM card information includes an IMSI number of the physical SIM card corresponding to the mirrored SIM card for which authentication is requested.

Further, in the step S40, the third authentication request signal includes:

the data head comprises the whole packet length and the serial number of a third authentication request signal, the data tail comprises a check code for data check of the identity card management equipment, and the Token code is a code randomly generated by the server.

Further, the step S50 includes:

s51, the identification card management equipment temporarily stores Token codes in the third authentication signals, and establishes a corresponding relation between the Token codes and the positions of the SIM cards.

Further, in the step S90, it further includes checking whether the Token code of the second authentication feedback signal is consistent with the Token code of the third authentication request signal.

Further, if the Token code of the second authentication feedback signal is consistent with the Token code of the third authentication request signal, transmitting the third authentication feedback signal to the base station;

if the Token code of the second authentication feedback signal is inconsistent with the Token code of the third authentication request signal, the step S10 is skipped.

The invention also discloses a SIM card remote authentication device, which is characterized in that the SIM card remote authentication device comprises:

the system comprises an identification card management device, at least one identification card management device and a plurality of physical SIM cards, wherein the identification card management device is provided with a plurality of physical SIM cards;

the identity identification card management equipment is electrically connected with the server;

the cloud terminal is used for communicating with the base station and is electrically connected with the server and the base station respectively.

1) In some specific embodiments, the identification card management device is connected to the physical SIM card through an ISO7816 interface. And after receiving the authentication request, the SIM card generates an encryption sequence by using information such as IMSI, key and the like which are written by an operator when issuing the card and stored in the SIM card, and a random number which is generated by an access network of the operator when authenticating and finally transmitted to the SIM card. After the sequence is generated, the sequence is returned to the identification card management device through the ISO7816 interface and finally transmitted to the access network. And the identification card management equipment receives the encryption sequence returned by the SIM card and returns the encryption sequence to the server through the network. In particular, before the identification card management device returns the encryption sequence to the server, the Token information corresponding to the current SIM card position is found out through the comparison table between the Token and the SIM card position stored before, and the Token information and the encryption sequence are packaged together and returned to the server. After receiving the data packet returned by the identification card management device, the server takes out Token information carried in the data packet, finds out the cloud terminal which previously requests the authentication packet according to the Token information, and returns the authentication result to the cloud terminal. And after receiving the authentication result, the cloud terminal returns the authentication result to the access network of the operator. The access network compares the result with an internally generated authentication result, if the result is consistent, the authentication is passed, otherwise, the service is refused.

In some specific embodiments, the cloud terminal device can use a mirrored SIM card in addition to the functionality of a generic terminal device. A SIM mirror card is a virtual card that is a collection of physical SIM card content data. The SIM mirror image card is responsible for generation by the subscriber identity module card management device and uploaded to the server background. The use of the mirror image SIM card in the cloud terminal 300 is realized by a SIM card simulator, which realizes the analysis and operation work of the mirror image SIM card. For cloud terminal devices, the mirror SIM card is not different from the general physical SIM card.

In contrast, the following simple authentication flow is schematically shown, and the process is as follows:

a) The terminal requests access to the operator access network and transmits a user identification code IMSI as a parameter to the operator access network;

b) After receiving the access request, the operator generates a random number RAND, and calculates a sequence value SRES by using the random number RAND, the subscriber identity IMSI and the stored key Ki and using an encryption algorithm. Then, the random number is sent to the terminal equipment;

c) After receiving the random number RAND, the terminal equipment calculates an encrypted sequence value by using the user identification code IMSI, the random number RAND and the secret key Ki stored in the terminal equipment and an encryption algorithm consistent with the access network;

d) The terminal returns the sequence value to the access network, after the access network receives the sequence value, the sequence value is compared with the sequence value generated in the prior art, if the sequence value is consistent with the sequence value, the access is legal equipment, the authentication is passed, and the equipment is allowed to be accessed; otherwise access will be denied.

In general, the terminal device does not have key information of the operator, and thus cannot independently complete the authentication task. The operator uses an IC card, i.e. a subscriber identity card, also called SIM card, for storing some of the necessary information. The subscriber identity IMSI, the key Ki, and access-related information such as the encryption algorithm are written into the SIM card by the operator when issuing the card. Then, the terminal equipment is used as a user identity recognition module and is inserted into the terminal equipment, and user identity verification is completed together with the terminal equipment. The SIM card integrates the CPU, the memory and the input/output module into one IC, so that the SIM card has certain data processing capacity. When the terminal needs to encrypt the random number sent by the operator access network, the random number is actually forwarded to the SIM card, the SIM card uses the information such as the internal CPU, the IMSI, the secret key and the like stored in the SIM card to encrypt the random number, and the result is returned to the terminal equipment to finally finish the authentication process.
