Description
Technical Field
The invention relates to the field of intelligent card processing, in particular to a method and a system for realizing remote card writing by using equipment long connection.
Background
With the wide development of the application of the internet of things, a large amount of card making and issuing data requests are required to be determined in advance in the production link of the smart card, so that the operation and management cost is greatly increased, and as an efficient alternative solution, the remote card writing of the card making data to the security chip of the terminal equipment in an over-the-air mode through the HTTPS or a short message channel resource is realized by providing a background server, so that the service flexibility of card making and issuing can be realized, and then card opening and activating can be realized as required, thereby bringing great convenience to operators and service providers.
The remote card writing at the present stage is mainly realized by two modes and two air channels:
[ Consumer Consumer model ]: one is a remote card writing request that triggers a Pull (Pull) card opening data to a server by a user manually clicking on an Application (Application) of a terminal device. After establishing an HTTPS connection with the remote server and obtaining the card making data, the card making data is written to the smart card via an interactive interface program LPA (Local Profile Agent ) between the application and the card. (applicable scenes include scenes such as a mobile phone, a tablet, a wearable device, and the like);
[ M2M machine-to-machine (without human intervention) mode ]: a method for using network operator's SMS network resource to Push (Push) data command from platform side in data SMS mode to trigger card to build HTTP connection to server and obtain remote card making data is suitable for some processing scene without artificial site (such as ammeter, gas meter or intelligent household remote card writing), if HTTPS connection from terminal equipment to server can not be built by command, card making data can be directly issued to card end through SMS channel and executed to achieve remote card writing purpose.
In addition to the two main modes mentioned above (LPA procedure pulls card data through HTTPS or platform pushes card data through sms), there are some intermediate promiscuous modes in practical applications, such as: and the user sends a specified short message request from the terminal, and pulls the scene of card making data to the server through a short message channel.
In the two approaches at the present stage, the technical application scenes have advantages and disadvantages and also have respective limitations.
1. [ Consumer Consumer model ]: the remote card writing scene is triggered by clicking a corresponding button on the terminal equipment by a consumer, and the application range of the remote card writing scene is limited. Because this approach limits the triggering conditions for remote writing, manual interaction is necessary to complete the request, i.e. it limits that someone as a consumer is on site, and the terminal is a device with an operating screen control to enable the solution. ( Another: the same is true for the situation of pulling card making data by using a short message channel, the situation that the use situation is necessary to be manual operation intervention on site is limited )
2. [ M2M machine-to-machine (without human intervention) mode ]: the purpose of remotely pushing the short message from the platform side to the equipment terminal to realize remote card writing can be realized through pushing the short message, so that the problem of application scenes without manual work on site is solved, but the short message channel resource is necessarily required to be consumed through information pushing in a short message mode, and the short message charge is too high relative to the flow of GPRS. The data carrying capacity of the short message channel is smaller, and the short message channel is another disadvantage of the short message mode.
In summary, regardless of the approach adopted, there are limitations in triggering a remote card writing request in an application of the internet of things. Based on the method, the invention constructs a method for realizing remote card writing by using the long connection of the equipment.

It should be noted that the purpose of the EID information obtained again at this time is to ensure the latest EID of the current smart card, so as to avoid the failure of executing the later instruction due to the EID mismatch caused by the card changing operation.
After receiving current EID information returned by the smart card, the terminal module forwards the current EID information to the terminal APP, the terminal APP obtains APPID sent by the server and EID returned by the smart card at the moment, uses the APPID and the EID as parameter information for establishing connection with the service application server, directly sends an HTTPS request to the service application server, receives a card execution instruction issued by the service application server, forwards the card execution instruction to the terminal module, sends the card execution instruction to the smart card, and the smart card establishes a BIP channel according to the card execution instruction and the terminal module, and establishes remote HTTPS connection between the terminal module and the server.

In this embodiment of the present application, the connection request sent by the terminal APP to the service application server is a device long connection, and may be an HTTP request, an FTP request, or an SFTP request, in addition to an HTTPS request.
Example two
As shown in fig. 2, the present invention provides a method for implementing remote card writing by using long connection of a device, which is applied to the system described in the first embodiment, and the method specifically includes:
step 210, the service application server sends a message push request to the terminal OS through the OS-level message server;
when the terminal APP is installed, an application identifier APPID is randomly generated according to the current hardware environment, the application identifier APPID and initial intelligent card EID information stored in the terminal are uploaded to a service application server to perform initial unique binding of the terminal APP and the intelligent card, and then if the intelligent card EID is changed, the binding relation stored in the service application server is updated in the operation process. When a service application server needs to initiate remote card writing to a terminal, the method specifically comprises the following steps: step 210-1, a service application server generates a message pushing request according to APPID, and forwards the message pushing request to an OS-level message server; step 210-2, the OS-level message server sends a message push request to the terminal OS.
Step 220, the terminal OS forwards a message notice to the terminal APP, the terminal APP initiates an instruction request to the terminal module to establish the machine card connection, and the terminal module sends an EID acquisition instruction to the smart card;
after receiving the message push request, the terminal OS acquires the APPID from the message push request, searches the corresponding terminal APP in the terminal, and forwards the message notification to the corresponding terminal APP.
Step 230, the smart card returns the stored current EID information to the terminal module according to the EID acquisition instruction;
because the EID mismatch caused by the card changing operation may occur, the later instruction execution fails, and therefore, when the remote card writing operation is performed, EID information needs to be obtained from the smart card again, so that the latest EID is ensured, and the EID stored in the terminal is updated.
Step 240, the terminal module forwards the obtained current EID information to the terminal APP, and the terminal APP sends an HTTPS request to the service application server;
and the terminal module generates an HTTPS request for acquiring the connection parameter information according to the latest acquired current EID information and the application identifier APPID, and sends the request to the service application server.
Step 250, the service application server generates a connection instruction according to the HTTPS request, and returns the connection instruction containing the connection parameter information to the terminal APP;
after receiving an HTTPS request sent by a terminal module, a service application server acquires an APPID and an EID from the HTTPS request, uses the APPID to search for the corresponding EID stored in the server, if the EID stored in the server is the same as the EID in the HTTPS request, the service application server indicates that no card exchange operation exists, directly uses the EID to generate unique connection parameter information, packages the unique connection parameter information into a smart card execution instruction data packet, returns an HTTPS response to a terminal APP, if the EID stored in the server is different from the EID in the HTTPS request, indicates that the card exchange operation occurs, updates the stored EID into the EID in the HTTPS request, uses the latest EID to generate the unique connection parameter information, packages the unique connection parameter information into the smart card execution instruction data packet, and returns the HTTPS response to the terminal APP;
the method specifically comprises the following steps of: and acquiring a corresponding algorithm and a key from a server memory according to the received EID, encrypting preset connection data (such as a service application server IP address), generating connection parameter information, assembling the connection parameter information into a 7816 card execution instruction, and returning an HTTPS response to the terminal APP.
Step 260, the terminal APP forwards the connection instruction to the terminal module, and the terminal module sends the connection instruction to the smart card;
step 270, the smart card establishes a BIP channel with the terminal module according to the connection parameter information in the connection instruction, informs the terminal module to open the BIP channel, and establishes a remote HTTPS connection with the service application server;
after the intelligent card informs the terminal module to open the BIP channel according to the connection parameter information, the terminal module opens the BIP channel and establishes remote HTTPS connection with the service application server, and communication data of the follow-up intelligent card and the server are transmitted through the terminal module directly without internal operation of the terminal.
In addition, in the process of establishing connection between the intelligent card and the service application server, the service application server needs to verify the identity of the intelligent card, so that the service application server and the intelligent card use a preset authentication mode to verify the identity, and after the verification is successful, the service application server sends service data to the intelligent card; the method specifically comprises the following substeps:
s1, a service application server and an intelligent card carry out identity verification in a preset authentication mode, service data are assembled into card execution instructions after verification is successful, and the service data are sent to the intelligent card through remote HTTPS connection and a BIP channel;
the preset authentication mode comprises, but is not limited to, authentication by using one or more modes such as a PSK pre-shared key mode, a certificate chain authentication mode, a public-private key asymmetric key mode and the like;
the PSK pre-sharing key mode specifically comprises the following steps: the method comprises the steps that a shared symmetric key is prefabricated in advance on a smart card and a service application server, then the smart card terminal is associated through a PSKID, a PSKID value is sent to the service application server in the process of needing handshake authentication, the service application server finds the associated key corresponding to the smart card according to the PSKID, and verification is completed through the associated key and random numbers generated in the handshake process. The certificate chain mode is specifically as follows: the intelligent card is pre-provided with a card certificate, the certificate is issued by a factory EUM, the EUM factory certificate is issued by a third party CI, and meanwhile, the service application server certificate is also issued by the third party CI, so that the identity validity check is achieved by mutually exchanging certificates in the process of handshaking and authenticating identities, and the certificates are under the same CI certificate chain. The public and private key mode is specifically as follows: the public key and the private key special for the intelligent card exist on the intelligent card, the public key and the private key special for the service application server also exist on the service application server, and in the process of handshaking authentication identity, the protection key required for encrypting transmission of the service sensitive data is calculated through negotiation by using the public key of the opposite party and the private key of the opposite party and using an ECC elliptic curve algorithm, so that the encryption transmission of the follow-up sensitive data is realized.
Taking a PSK pre-sharing key mode as an example, the service application server and the smart card use a preset authentication mode to carry out identity verification, and the method specifically comprises the following steps: (1) the intelligent card sends ClientHello information to a service application server for key exchange, wherein the ClientHello information comprises a TLS version number, a client random number, a session ID, an encryption algorithm and PSKID extension information; (2) the service application server finds corresponding associated key information according to the PSKID, encrypts the ServerHello information and then sends the ServerHello information to the intelligent card, wherein the ServerHello information comprises a server random number, a selected encryption algorithm and PSKID expansion information encrypted by the corresponding key, and the service application server generates a session key according to the client random number, the server random number and a agreed key algorithm for later service data transmission; (3) the smart card also finds the preset associated key to verify the encryption information returned by the service application server according to the PSKID, and generates a session key according to the client random number, the server random number and the agreed key algorithm for later service data transmission. The smart card is thereby successfully authenticated with the service application server.
S2, the intelligent card executes service data, and the execution result is sent to a service application server through a remote HTTPS connection and a BIP channel;
and S3, the service application server judges whether to continue to send other more service data according to the service logic, if no more service data need to be sent, an HTTPS response is returned (for example, 204 is a status code) to indicate that the service operation interaction request is ended and no subsequent data need to be sent. If there are other traffic data transmissions, execution returns to S1.
By adopting the technical scheme, the following technical effects can be achieved:
(1) By utilizing long connection of an operating system level, the message can be pushed to the APP application program of the terminal equipment from a remote Profile server, so that manual intervention operation required in the prior art can be avoided.
(2) The terminal APP establishes an HTTPS channel to acquire configuration address information of the Profile, and the configuration address information is determined by pushing the content in the message, so that the method has greater flexibility compared with the prior art in which the terminal APP directly accesses the Profile by a mode of prefabricating a default address.
(3) Through the card writing data obtained from the Profile server, the smart card establishes a BIP channel in the process of executing the card instruction, establishes HTTPS connection with the server, obtains card making data through the channel, and does not need to pass through the terminal APP. The mode has greater security and simplicity due to encryption and decryption operations related to card instructions.
The foregoing embodiments have been provided for the purpose of illustrating the general principles of the present invention in further detail, and are not to be construed as limiting the scope of the invention, but are merely intended to cover any modifications, equivalents, improvements, etc. based on the teachings of the invention.
