Electronic devices with smart cards are currently mainly used for data transmission by calling an operating system of the electronic device with the smart card, and along with the improvement of the requirements of the electronic device on security, the electronic device has more and more restrictions on the operating system, for example, only supporting the application of the electronic device to call the operating system and perform data transmission with the smart card.

With the increase of functions of the electronic device, more and more applications are additionally installed in the electronic device, so that according to the current data transmission method of the electronic device and the smart card, certain applications in the electronic device are easy to cause that the applications do not have permission to call an operating system, and further cannot perform data transmission with the smart card.

Therefore, the embodiment of the application provides a data transmission method and device based on a smart card, the smart card, equipment and medium, which can solve the problem that some applications of electronic equipment in the related technology cannot perform data transmission with the smart card.

The data transmission method, device, smart card, device and medium based on the smart card provided by the embodiment of the application are described in detail below with reference to specific scenes and embodiments.

Fig. 1 is a flowchart of a data transmission method based on a smart card according to an embodiment of the present application, where, as shown in fig. 1, the data transmission method based on a smart card may include the following steps:

S110, receiving a command data packet through a fixed dialing channel of the electronic equipment.

Wherein the command data packet includes identification information and command content.

S120, corresponding operation is carried out on the command content according to the identification information, and an operation result is obtained.

S130, sending an operation result to the electronic equipment through the fixed dialing channel.

The following describes the above steps in detail, as follows:

In S110, the electronic device may be a mobile phone, a smart band, a smart watch, a vehicle-mounted communication device, etc. mounted with a smart card, and a fixed dial channel is provided in the electronic device. Through the fixed dialing channel, the self-contained application or the non-self-contained application in the electronic equipment can carry out data transmission with the intelligent card, and the problem that certain applications of the electronic equipment in the related technology cannot carry out data transmission with the intelligent card is effectively solved. And the data transmitted by the fixed dialing channel can be monitored at fixed time through the fixed dialing channel.

The command data packet is a data packet generated by the electronic device and sent to the smart card. For example, the command packet may include identification information and command content, the identification information being used to characterize a command type of the command content, different identification information may correspond to different command types. The identification information may be represented by a tag, for example. The manner of representation and meaning of the identification information may be agreed with the operating system of the electronic device.

The command type can comprise a read type or a write type, for example, that is, the embodiment of the application can not only write data into the smart card, but also read data from the smart card, thereby realizing two-way communication of the data.

The command content may include, for example, fixed dialing content or non-fixed dialing content, which may be set according to actual needs.

In S120, the smart card may perform a corresponding operation on the command content based on the identification information carried by the command packet, to obtain an operation result.

Illustratively, the smart card may determine a command type of the command content according to the identification information; and executing corresponding operation on the command content according to the command type to obtain an operation result.

For example, when the command type is a read type, i.e., the electronic device needs to read data from the smart card, the smart card may take the data content of the read data as the operation result. For another example, when the command type is a writing type, that is, the electronic device needs to write data into the smart card, for example, needs to switch the code number 1 to the code number 2 to log on the network, and after the smart card is switched, an operation result of successful or failed switching can be generated.

For example, in the case that the identification information is empty, determining that the command type of the command content is a read type or a write type;

under the condition that the identification information is the first identification information, determining that the command type of the command content is a reading type;

and in the case that the identification information is the second identification information, determining that the command type of the command content is a writing type.

For example, when the identification information is empty, that is, no tag, the command content may be determined to be the fixed dialing content, and at this time, the electronic device may write the fixed dialing content into the smart card, or may read the fixed dialing content from the smart card, that is, the corresponding command type is a read type or a write type.

For example, the electronic device may write the fixed dialing content to the smart card when the fixed dialing content is not present in the smart card, and may read the fixed dialing content from the smart card when the fixed dialing content is present in the smart card.

The first identification information is used to characterize the read type, e.g. the first identification information may be denoted 0070, but may of course be denoted in other forms, in particular in relation to the commitment of the operating system.

The second identification information is used to characterize the writing type, for example, the second identification information may be represented as 0371, or 0599, etc., where 0371 is used to represent the update operation and 0599 is used to represent the code number switching operation.

For example, when the tag is #0070# 364637445 (6F 7E ASCII), it indicates that the electronic device needs to read the 6F7E file from the smart card, and the smart card finds the 6F7E file according to the tag, and returns the content in the 6F7E file to the electronic device through the fixed dial channel.

Illustratively, when tag is #0371# 36463142, it indicates that the electronic device needs the smart card to update the 6F7B file, and instructs the smart card to encrypt the updated 6F7B file using the 03 group key. Wherein, the operating system presets 10 groups of keys, and the key index serial numbers are 01, 02, … and 10 respectively.

For example, when tag is #0599#03, it indicates that the electronic device needs the smart card to perform the code number switching operation, and the electronic device switches from the code number 1 to the code number 2 to log on.

In the embodiment of the application, after the intelligent card receives the command data packet sent by the electronic equipment, the identification information in the command data packet can be analyzed, the command type of the command content is judged, and the reading or writing operation is executed on the command content based on the command type, so that the data can be written into the intelligent card, the data can be read from the intelligent card, and the processing type of the data is increased.

In S130, after the smart card obtains the operation result, the operation result may be returned to the electronic device, so as to implement bidirectional communication between the electronic device and the smart card.

In some embodiments, when the identification information is non-null, that is, the command content is non-fixed dial content, in order to ensure the security of data transmission, the electronic device may encrypt the command content, where the encryption key may use any one of 01-10 sets of keys, and at this time, the command data packet may include a key index sequence number corresponding to the encryption key.

Based on this, in some embodiments, the smart card-based data transmission method may further include the steps of, prior to S120:

Acquiring a key corresponding to the key index serial number;

Decrypting the command content according to the secret key to obtain decrypted command content;

executing corresponding operation on the command content according to the identification information to obtain an operation result, wherein the operation result comprises the following steps:

And executing corresponding operation on the decrypted command content according to the identification information to obtain an operation result.

And obtaining a corresponding key from the preset 10 groups of keys according to the key index sequence number, and decrypting the command content by using the key to obtain the decrypted command content.

Accordingly, the step S120 may include the steps of:

Illustratively, the smart card can execute corresponding operation on the decrypted command content according to the identification information to obtain an operation result.

In the embodiment of the application, when the command content is the non-fixed dialing content, the electronic equipment can encrypt the command content, so that the safety of data transmission is ensured.

In some embodiments, after S110, the smart card-based data transmission method may further include the steps of:

The command packet is stored.

In the embodiment of the application, after the intelligent card receives the command data packet sent by the electronic equipment, the command data packet can be cached, so that the condition that the intelligent card loses data due to power failure, card pulling and other reasons in the data processing process can be prevented.

Taking application to electronic devices as an example, as shown in fig. 2, the data transmission method based on the smart card may include the following steps:

s210, acquiring a command data packet.

S220, the command data packet is sent to the intelligent card of the electronic equipment through the fixed dialing channel.

S230, receiving an operation result sent by the intelligent card and aiming at the command data packet.

The intelligent card executes corresponding operation on the command content in the command data packet according to the identification information in the command data packet to obtain the operation result.

The following describes the above steps in detail, as follows:

In S210, the command packet may be obtained by the electronic device grouping the acquired data content, and the command packet may be identified by the smart card. The data content can be sent to the electronic device by a server or any other form, and when the data content is the non-fixed dialing content, the electronic device can encrypt the data content to ensure the security of data transmission.

In S220, after the electronic device generates the command data packet, the command data packet may be sent to the smart card through the fixed dial channel, so that the problem that the data cannot be transmitted due to the unauthorised call of the operating system of the electronic device by the application additionally installed in the electronic device can be effectively avoided.

In some embodiments, the fixed dial channel may be displayed through the interface shown in fig. 3, and when the user clicks on "fixed dial channel" in the interface, as shown in fig. 4, the user may enter a command packet at the fixed dial channel interface.

In some embodiments, the interface shown in fig. 3 may not be displayed, i.e. the electronic device may directly invoke the fixed dial channel and transmit the command packet via the application protocol data unit (Application Protocol data unit, APDU).

In S230, the electronic device may also receive the operation result sent by the smart card and directed against the command data packet, that is, the electronic device may not only send data to the smart card, but also receive data sent by the smart card, thereby implementing bidirectional data transmission and improving diversity of data transmission.

In some embodiments, the smart card-based data transmission method may further include the steps of, prior to S220:

the method comprises the steps of carrying out identity verification on a user of electronic equipment to determine whether the user has operation authority of a fixed dialing channel;

Accordingly, sending a command data packet to the smart card of the electronic device through the fixed dial-up channel includes:

and under the condition that the user is determined to have the operation authority of the fixed dialing channel, sending a command data packet to the intelligent card through the fixed dialing channel.

The identity of the user may be checked, for example, by means of a PIN2 (Personal identification number, PIN 2) before the data is transmitted using the fixed dial channel. The PIN2 code is a personal identification code to be input when entering a special function such as a fixed dialing function, a call charging function, etc. For example, in the embodiment of the present application, when data needs to be transmitted by using a fixed dial channel, a user is required to input a PIN2 code to verify the identity of the user.

Only if the identity of the user passes the verification, that is, if the user has the authority to operate the fixed dialing channel, the fixed dialing channel of the electronic device and the smart card can be used for data transmission, so that misoperation can be avoided.

In some embodiments, in case the command type of the command content is a read type, the smart card-based data transmission method may further include the steps of, after S230:

And displaying the operation result on the interface where the fixed dialing channel is located.

For example, taking the example of reading the 6F7E file, when the electronic device receives the operation result sent by the smart card, the content of the 6F7E file may be extracted, and the content may be displayed on the interface of the fixed dial channel in one or more forms. For example, it can be shown as: MCCMNC location information: xxxxx, location information update status: xxx.

In some embodiments, the operation result may further include a file for detecting a smart card network connection condition, and at this time, the electronic device may read a value of the corresponding file from the operation result, and determine whether the smart card network connection is successful based on the value.

In the embodiment of the application, after the intelligent card processes the command data packet, the processing result or the content needing to be returned is returned to the electronic equipment through the fixed dialing channel, so that the bidirectional transmission of data is realized, and meanwhile, the electronic equipment displays the processing result or the content returned by the intelligent card on the interface where the fixed dialing channel is located, so that the user can conveniently know the processing result of the data.

In some embodiments, in a case where the command type of the command content is a write type and the operation result is an operation failure, the smart card-based data transmission method may further include the steps of:

the command packet is retransmitted through the fixed dial channel.

By taking code number switching as an example, if the operation result returned to the electronic device by the smart card is switching failure, the electronic device can send relevant command data packets to the smart card again, so that the success rate of switching is ensured.

The embodiment of the application utilizes the inherent fixed dialing channel of the electronic equipment to carry out data transmission with the intelligent card, thereby not only avoiding the problem that the additionally installed application in the electronic equipment cannot transmit data due to unauthorized call of the operating system of the electronic equipment, but also realizing two-way communication, and carrying out data transmission through the fixed dialing channel, requiring certain authority, and avoiding misoperation.
