[0030] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0032] The term "including" and its variations used herein are open inclusions, i.e., "including but not limited to". The term "based on" means "based at least in part on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". The relevant definitions of other terms will be given in the following description.

[0033] It should be noted that the concepts such as "first" and "second" mentioned in this application are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0034] It should be noted that the modifications of "one" and "plurality" mentioned in the present application are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0035] The following is a detailed description of the method for transmitting prop data provided by the present application in conjunction with the accompanying drawings and specific implementation methods.

[0036] Figure 1 This is a flow chart of a method for transmitting prop data in an embodiment of the present application. This embodiment is applicable to data transmission in a network-free device. The method can be executed by a prop data transmission device. The prop data transmission device can be implemented in software and / or hardware. The prop data transmission device can be configured in a first device.

[0037] The first device has networking functions and near field communication (NFC) functions.

[0038] The networking function refers to the ability of the first device to connect to the Internet and perform data transmission and communication through a wired or wireless network. The wireless network may include: cellular network, wireless fidelity (WIreless-FIdelity, WI-FI), Bluetooth (Bluetooth, BT), etc. The network may include: mobile fourth generation mobile communication technology (4G), fifth generation mobile communication technology (5G), sixth generation mobile communication technology (6G), etc.

[0039] NFC is a short-range high-frequency wireless communication technology that allows two devices to exchange data within a few centimeters. NFC has a variety of application scenarios, including but not limited to: mobile payment, data exchange, smart tag reading, access control, smart home control. The embodiment of this application mainly uses the data transmission function of NFC.

[0040] The first device can not only connect to the Internet to carry out various online activities and data transmission, but also quickly and conveniently exchange data with other NFC-enabled devices or tags within a short distance. Exemplarily, the first device includes but is not limited to: a smartphone, a smart watch, a wearable device, a tablet computer, a laptop computer, etc. In the embodiment of the present application, the first device is taken as an example to illustrate.

[0041] The method for transmitting prop data provided in the embodiment of the present application mainly utilizes the first device to transmit the prop data to the second device. The second device cannot be connected to the Internet. In other words, the second device cannot be connected to the Internet or the local area network, and cannot perform online activities and data transmission. There are mainly two situations in which the second device cannot be connected to the Internet: one is that the second device is in a networkless environment, such as an underground garage; the other is that the second device itself does not have the networking function, for example, the communication module is not installed, or the communication module fails and cannot be used normally. The above-mentioned second device includes but is not limited to: handheld game consoles, baseband-free mobile phones, etc.

[0042] like Figure 1 As shown, the method for transmitting prop data provided in the embodiment of the present application mainly includes steps S101-S103.

[0043] A game client matching the game in the second device is installed in the first device, and the embodiment of the present application is mainly executed by the game client installed in the first device.

[0044] S101. Display a prop selection page, which includes a plurality of prop identifiers, each of which corresponds to an inactive prop instance object. The prop instance object stores prop data, which is sent from the server to the first device.

[0045] The item selection page is a page displayed in the game client, which includes multiple item identifiers, where the item identifier may include an item ID, an item name, an item attribute, and the like.

[0046] Furthermore, the prop identification included in the prop selection page can be displayed in the form of an NFC card, which can also be called a prop card. The prop identification included in the prop selection page has the corresponding prop data stored in the first device. In other words, the prop data is stored in the first device, and the prop card corresponding to the prop data will be displayed in the prop selection page.

[0047] In one possible implementation, a game client sends a prop data request to a server through a network connection. The server sends the prop data to the game client based on the prop data request and writes the prop data into an applet instance object to obtain a prop instance object. After the prop instance object is generated, the prop identifier of the prop data is displayed in the prop selection page. The prop identifier can be displayed in the form of a prop card.

[0048] Inactive prop instance objects do not expose their functions, thus increasing data security. Unselected Applets cannot be accessed externally, reducing potential security risks.

[0049] Furthermore, inactive item instance objects are stored on the SE chip, which can further enhance data security.

[0050] When the game player wants to transfer props to the second device, in response to the game player's selection page display instruction for the game client, the prop selection page is displayed in the interface of the game client, and the prop selection page includes multiple prop identifiers.

[0051] S102: In response to a selection operation on a prop identifier, setting the prop instance object corresponding to the selected prop identifier to an activated state.

[0052] The above selection operation may include a trigger operation for the prop identifier, and the trigger operation includes single-click, double-click, slide and other operations.

[0053] In response to the selection operation for the prop identifier, it can be understood that the game player wants to transfer the prop data corresponding to the selected prop identifier to the second device. At this time, the prop instance object corresponding to the selected prop identifier is set to an activated state to open the access rights of the prop instance object.

[0054] S103. After establishing an NFC communication connection with the second device, the prop data in the prop instance object in the activated state is transmitted to the second device through the NFC communication connection.

[0055] In the embodiment of the present application, in response to the NFC activation instruction, the first device activates the NFC function and sets the NFC function of the first device to the listening mode. The order of activation of the NFC function and activation of the prop instance object is not limited. The NFC function can be activated first and then the prop instance object can be activated, or the prop instance object can be activated first and then the NFC function can be activated.

[0056] The APDU instructions are used to perform interactive communication between the first device and the second device.

[0057] Further, the game player turns on the NFC function of the second device and enters the process of obtaining props. The second device attempts to find the prop card and sends a select applet instruction to the SE chip in the first device. The first device sends a select applet response to the second device.

[0058] Among them, select the Applet instruction: 00A4040008A000544D43415050; select the Applet response: 6F108408A000544D43415050A5069F6501FF9000.

[0059] In the selection command, 00A4 represents selection, 04 is selected by Applet ID, 08 is length, and A000544D43415050 is the ID of the prop card Applet. Select the response to install the FCI template for combination. 6F represents the FCI template structure, 10 is the template structure data length, 84 is the Applet ID, 08 is the ID length, A000544D43415050 is the prop card ID, A5 is the unique data, 9F65 is used to indicate the maximum length of communication data, and its length is FF. 9000 represents that the process is normal and the instruction is correct.

[0060] The first device and the second device turn on the NFC function, send a selection instruction, and perform two-way authentication through NFC. The process of performing two-way authentication through NFC includes: 1) Initiate a connection request: one device, as the initiator, sends a connection request to the other device. The connection request may contain some preliminary identity information or an authentication request. 2) Respond to the request: After receiving the request, the receiving device will verify whether the identity information of the initiator meets the preset security standards. If the verification is successful, a confirmation message will be responded; if it fails, the connection will be rejected. 3) Initiator verification: After receiving the response, the initiator device will also verify the information in the response to confirm the identity of the receiver. 4) Establish a secure connection: After the two devices have gone through the above mutual authentication process, they can determine that the other party is trustworthy, thereby establishing a secure NFC connection. On this connection, the two parties can perform further prop data transmission. Among them, the first device can be the initiating device, and correspondingly, the second device is the receiving device. The second device can be the initiating device, and correspondingly, the first device is the receiving device.

[0061] After the two-way authentication is passed, after the first device receives the prop acquisition instruction sent by the second device, it sends the prop data to the second device as a response. After the second device receives the prop data, it sends a successful reception message to the first device. After successful reception, the SE chip records the successful transmission of the prop data.

[0062] Among them, the request prop acquisition instruction: 80CAF9F700; the response prop data: F9F7XXYY...ZZ9000.

[0063] In the request prop acquisition instruction, 80 is the GP platform type instruction, CA is to obtain data, F9F7 is the prop data, and 00 means no subsequent data. In the response prop data, F9F7 corresponds to the prop data in the request, XX is the data length, YY...ZZ is the prop data content, and the length is XX. 9000 means the process is normal and the instruction is correct.

[0064] Item data content YY...ZZ: It consists of an 8-byte item ID and several bytes of item attributes. The item ID is the name and image of the specific item issued, and the item attributes determine the purpose and effect of the item. At the same time, if the item ID cannot be found in the game database, it is an invalid ID.

[0065] The embodiment of the present application provides a method, device, equipment and storage medium for transmitting prop data, the method comprising: the server sends the prop data to the first device, the first device includes a plurality of prop instance objects, and the prop data is stored in the prop instance object; the first device displays a prop selection page, and the prop selection page includes a plurality of prop identifiers, the user can perform a selection operation for the prop identifier in the prop selection page, and the first device sets the prop instance object corresponding to the selected prop identifier to an activated state. Finally, after the first device establishes an NFC connection with the second device, the prop data stored in the prop instance object in the activated state is transmitted to the second device. Since the props are provided to the second device through NFC technology, the online purchase of virtual props is realized, the game content is increased, and the playability of the game is improved.

[0066] On the basis of the above-mentioned embodiments, the present application further optimizes the method for transmitting prop data. Figure 2 As shown, the optimized prop data transmission method includes S201-S211.

[0067] S201, generating a prop data request.

[0068] The prop data request may be understood as an instruction generated by the first device for requesting the server to send the prop data.

[0069] The game client of the first device includes a prop store. When a game player opens the prop store of the game client, the game player selects a prop that he wants to buy in the prop store. The first device generates a prop data request in response to the selection operation of the game player in the prop store. The prop data request includes a prop name, icon, attributes, etc.

[0070] In a possible implementation, a game client of the first device establishes a network connection with a server, and then the game client performs a two-way authentication with the server through a built-in SE chip of the first device.

[0071] Mutual Authentication refers to the process of mutual authentication between the communicating parties (game client and server). Mutual authentication ensures that both the client and server can confirm the true identity of each other, thereby preventing security threats such as third-party attacks. When using SE chips for mutual authentication, public key infrastructure (PKI), digital certificates, encryption algorithms and other technologies are mainly used.

[0072] The main process of the game client performing two-way authentication with the server through the SE chip built into the first device includes:

[0073] 1) The game client initiates a connection request to the server.

[0074] 2) The game client and server exchange their respective digital certificates to verify each other's identity.

[0075] The game client checks whether the certificate provided by the server is valid (such as whether the certificate has expired, whether it is issued by a trusted CA, etc.), and the server also verifies the validity of the client certificate.

[0076] The digital certificate of the game client is applied for by the game client to the certificate authority (CA). The digital certificate contains the public key and identity information of the game client and is signed by the CA to ensure its authenticity. The digital certificate of the server is applied for by the server to the CA. The digital certificate contains the public key and identity information of the server.

[0077] 3) The game client verifies the server.

[0078] The game client uses the server's public key to decrypt a signed message sent by the server (the message may contain some random numbers or timestamps to prevent replay attacks). If the decryption is successful and the message content is correct, it means that the server has the corresponding private key and the identity verification is successful.

[0079] 4) The server verifies the client.

[0080] The server will also use the client's public key to verify the signed message sent by the client to confirm the client's identity.

[0081] 5) Establish a safe channel.

[0082] Once both parties (game client and server) have completed authentication, they will negotiate a session key to encrypt subsequent data transmission. This is done through a key exchange protocol such as Diffie-Hellman to ensure that even in the case of network monitoring, a third party cannot learn the session key.

[0083] Establishing a secure pass means two-way authentication between the game client and the server. The main function of the SE chip is to safely store the private key and perform related encryption operations, such as generating digital signatures, to ensure the security of the key and the non-repudiation of the operation.

[0084] S202: Send a prop data request to the server, where the prop data request is used to instruct the server to send the prop data.

[0085] After the two-way authentication is passed, the first device generates a prop data request in response to the selection operation of the game player in the prop store, and sends the prop data request to the server.

[0086] Furthermore, the game client can send a prop data request to the server through the secure channel established between the game client and the server. After receiving the prop data request, the server performs a legality and integrity check on the prop data request, and after the check passes, sends the prop data to the first device.

[0087] Legitimacy verification is the process by which the server ensures that the source of the item data request is legitimate and that the requester has the right to perform a specific operation. In computer systems and network security, legitimacy verification usually includes two main parts: identity verification and authorization verification. Identity verification refers to verifying the true identity of the requester. Common authentication methods include: username and password, access token, digital certificate, signature verification, etc. Authorization verification refers to the server's determination of whether the game client has the right to perform a specific operation or access a specific resource. Common authorization verification methods include: role-based access control, rights list, access control list, etc.

[0088] The main process of checking the legitimacy and integrity of prop data requests includes: extracting identity information from prop data requests, such as user ID, access token, signature, etc. Identity verification: check whether the user ID exists in the system; check the validity, expiration time and permission range of the token; recalculate the signature using the same hash function and key, and compare it with the signature in the request to ensure that the data has not been tampered with. Authorization verification: verify whether the user has the right to perform the operation based on the user's role or permission list; if the request involves a specific resource, check whether the user has the right to access the resource. If both identity verification and authorization verification pass, the prop data is sent to the first device. If any step of verification fails, the corresponding error information is returned to the first device, such as "invalid user ID", "invalid token", "no access", etc.

[0089] The server verifies the legitimacy and integrity of item data requests to further ensure system security and data accuracy.

[0090] Furthermore, the game client encrypts the prop data request using the session key negotiated by both parties through the SE chip, and the game client can send the encrypted prop data request to the server through the secure channel established between the game client and the server. After receiving the encrypted prop data request, the server decrypts the encrypted prop data request, performs a legality and integrity check on the decrypted prop data request, and sends the prop data to the first device after the check passes.

[0091] The encryption algorithm of the game client and the decryption algorithm of the server are determined by negotiation between the two parties, and the encryption and decryption algorithms are not specifically limited in the embodiments of the present application.

[0092] Encrypting the transmission of prop data requests can improve the security of data transmission.

[0093] S203, receiving the prop data sent by the server, and verifying the prop data.

[0094] The game client receives the prop data downloaded by the server and verifies the legitimacy and integrity of the prop data. If the verification passes, a reception completion response is sent to the server. At this point, the process of the server sending the prop data to the first device ends.

[0095] The process of verifying the legitimacy and integrity of item data by the game client is the same as the process of verifying the legitimacy and integrity of item data requests by the server. For details, please refer to the description in the above embodiment and will not be repeated in the embodiments of this application.

[0096] In a possible implementation, after receiving the prop data request sent by the game client, the server obtains the prop data corresponding to the prop data request, encrypts the prop data using the session key, and sends the encrypted prop data to the game client of the first device. The game client verifies the legitimacy and integrity of the encrypted prop data, and if the verification passes, sends a reception completion response to the server.

[0097] S204: After verification, the item data is sent to the SE chip.

[0098] The game client receives the prop data sent by the server and verifies the legitimacy and integrity of the prop data. If the verification passes, it sends a reception completion response to the server and sends the prop data to the SE chip.

[0099] Further, such as Figure 3 As shown, the first device 10 includes a game client 11 and a SE chip 12. The game client 11 receives the encrypted prop data sent by the server, and verifies the legality and integrity of the encrypted prop data. If the verification passes, it sends a reception completion response to the server and sends the encrypted prop data to the SE chip 12. The SE chip parses the encrypted prop data and then decrypts the encrypted prop data according to the session key to obtain the decrypted prop data, that is, the plaintext data of the prop.

[0100] The session key and encryption / decryption algorithm are negotiated after the SE chip and the server establish a secure channel. The encryption / decryption algorithm used is not specifically limited in the embodiments of the present application.

[0101] S205: Create an instance object in the SE chip.

[0102] Among them, the instance object refers to the specific object created according to the class. A class is a template or blueprint that defines a set of attributes (variables) and methods (functions), and the instance object is a specific entity created according to this template. Each instance object has its own state (attribute value) and behavior (method). The above instance object is an applet instance object. In Java, Applet is a special component and a small application running in the SE chip. The Applet instance object is an instance of the java.applet.Applet class, which is usually automatically created and managed by the game client.

[0103] The process of creating an instance object in the SE chip includes: transferring the compiled Applet code and data to the SE chip and registering them in the file system of the SE chip, actually creating an instance object of an Applet on the SE chip, and registering the Applet instance object in the SE chip operating environment so that it can receive and process APDU commands.

[0104] S206. Write the prop data into the instance object through the SE chip to obtain the prop instance object.

[0105] After the applet application is installed in the SE chip, the prop data is written into the instance object in the applet application to obtain a prop instance object, which can be understood as a virtual prop card, that is, a prop card is created in the SE chip, and the prop data is stored in the prop card. A prop card stores the prop data of a prop.

[0106] S207. Set the prop instance object to an inactive state.

[0107] In the SE chip, the Applet instance object can be in different states, among which the "inactive state" means that the Applet has been installed on the SE chip but has not been selected or activated. In this state, the Applet instance object will not process any APDU commands or perform any operations.

[0108] In the present application embodiment, Figure 4As shown, the first device 10 includes a game client 11 and a SE chip 12, wherein the game client 11 sends a prop card creation instruction to the SE chip 12, and after the SE chip 12 receives the prop card creation instruction, it executes the prop card creation process. The prop card creation process mainly includes: creating an Applet instance object in the SE chip, and then writing the prop data to the Applet instance object to obtain the prop instance object. At this time, the prop instance object is in an inactive state by default, and this state can only be operated through the game client, and the external device does not have access to the Applet. When the game client selects the prop identifier, that is, the Applet instance object is activated, the second device can try to receive the prop data.

[0109] An applet instance object is created in the SE chip, and the plain text data of the props is written into the instance object. The instance object is in an inactive state by default. The inactive applet instance object does not expose its functions, thereby increasing the security of the system. Unselected applet cannot be accessed externally, reducing potential security risks.

[0110] S208: Displaying a prop selection page, which includes a plurality of prop identifiers.

[0111] S209: In response to the selection operation on the prop identifier, the prop instance object corresponding to the selected prop identifier is set to an activated state.

[0112] The first device includes a plurality of prop instance objects, in which prop instance objects are stored prop data, and the prop data is sent from the server to the first device.

[0113] S210. After establishing an NFC communication connection with the second device, the prop data in the prop instance object in the activated state is transmitted to the second device through the NFC communication connection.

[0114] S208-S210 provided in the embodiment of the present application is the same as the process of S101-S103 provided in the above embodiment. For details, please refer to the description in the above embodiment, which will not be repeated in the embodiment of the present application.

[0115] S211. After receiving the successful reception message, delete the prop instance object in the SE chip and the prop data stored in the prop instance object.

[0116] The reception success message is used to indicate that the second device has successfully received the prop data.

[0117] In one possible implementation, after receiving a successful reception message, the prop instance object in the SE chip and the prop data stored in the prop instance object are deleted, including: after receiving a successful reception message, querying the status of the prop instance object in the SE chip; when the status of the prop instance object is successful transmission, deleting the prop instance object in the SE chip and the prop data stored in the prop instance object.

[0118] like Figure 5 As shown, after the prop data transmission is completed, the SE chip 12 sends a successful reception message to the game client 11. After the game client receives the successful reception message, it queries the successful delivery record of the props in the SE chip. If the status of the prop instance object in the SE chip is that the transmission is successful, the prop instance object and the prop data will be deleted, and the game client interface will prompt the user, and the prop data transmission process is completed.

[0119] Figure 6 This is a flowchart of a method for transmitting prop data applied to a second device in an embodiment of the present application. This embodiment can be applicable to data transmission between devices without a network. The method can be executed by a transmission device for prop data. The transmission device for prop data can be implemented in software and / or hardware. The transmission device for prop data can be configured in the second device.

[0120] Among them, the second device cannot be connected to the Internet, in other words, the second device cannot be connected to the Internet or local area network, and cannot perform online activities and data transmission. There are mainly two situations in which the second device cannot be connected to the Internet: one is that the second device is in a networkless environment, such as an underground garage; the other is that the second device itself does not have the Internet function, for example, the communication module is not installed, or the communication module is faulty and cannot be used normally. The above-mentioned second device includes but is not limited to: handheld game consoles, baseband-free mobile phones, etc.

[0121] The second device has an NFC function. The NFC function can be described in the above embodiment, and will not be repeated in the embodiment of the present application.

[0122] like Figure 6 As shown, the method for transmitting prop data provided in the embodiment of the present application mainly includes steps S601-S602.

[0123] S601: Establish an NFC communication connection with a first device.

[0124] In an embodiment of the present application, the second device responds to the NFC enable instruction, the second device enables the NFC function, and sets the NFC function of the second device to the active mode or the initiator mode. The second device in the active mode is in an active state and can initiate a communication request. The second device actively searches for nearby NFC devices and initiates a communication request. Once the first device is found, a select applet instruction is sent to the first device. After receiving the applet instruction, the first device sends a select applet response to the second device.

[0125] Among them, select the Applet instruction: 00A4040008A000544D43415050; select the Applet response: 6F108408A000544D43415050A5069F6501FF9000.

[0126] In the selection command, 00A4 represents selection, 04 is selected by Applet ID, 08 is length, and A000544D43415050 is the ID of the prop card Applet. Select the response to install the FCI template for combination. 6F represents the FCI template structure, 10 is the template structure data length, 84 is the Applet ID, 08 is the ID length, A000544D43415050 is the prop card ID, A5 is the unique data, 9F65 is used to indicate the maximum length of communication data, and its length is FF. 9000 represents that the process is normal and the instruction is correct.

[0127] The first device and the second device turn on the NFC function, send a selection instruction, and perform two-way authentication through NFC. The process of two-way authentication can refer to the description in the above embodiment.

[0128] After the mutual authentication process, both devices can determine that the other party is trustworthy, thus establishing a secure NFC connection. On this connection, both parties can further transmit prop data.

[0129] S602: Receive prop data transmitted by the first device through the NFC communication connection. The prop data is stored in the prop instance object. The prop data is sent from the server to the first device.

[0130] After the NFC connection is established, the second device sends a request to obtain the props instruction to the first device. After receiving the request to obtain the props instruction sent by the second device, the first device sends the props data to the second device as a response. After receiving the props data, the second device sends a successful reception message to the first device. After successful reception, the SE chip records the successful transmission of the props data.

[0131] Among them, the request prop acquisition instruction: 80CAF9F700; the response prop data: F9F7XXYY...ZZ9000.

[0132] In the request prop acquisition instruction, 80 is the GP platform type instruction, CA is to obtain data, F9F7 is the prop data, and 00 means no subsequent data. In the response prop data, F9F7 corresponds to the prop data in the request, XX is the data length, YY...ZZ is the prop data content, and the length is XX. 9000 means the process is normal and the instruction is correct.

[0133] Item data content YY...ZZ: It consists of an 8-byte item ID and several bytes of item attributes. The item ID is the name and image of the specific item issued, and the item attributes determine the purpose and effect of the item. At the same time, if the item ID cannot be found in the game database, it is an invalid ID.

[0134] The process of the server sending the prop data to the first device and the first device generating the prop instance object can refer to the description in the above embodiment and will not be described in detail in the embodiment of the present application.

[0135] In one possible implementation, after receiving the prop data, the second device verifies the prop data; after the verification passes, a reception success message is sent to the security component SE chip of the first device, and the reception success message is used to instruct the SE chip to record the prop instance object as successfully transmitted.

[0136] After receiving the prop data, the second device performs a legality and integrity check on the prop data to further ensure the correctness of the data. If the check succeeds, a reception success message is sent to the SE chip of the first device. If the check fails, an error message is sent to the first device, and a prop acquisition request instruction is sent to the first device again.

[0137] The process of the second device verifying the legitimacy and integrity of the prop data is the same as the verification process of the server end for the prop data request in the above embodiment. For details, please refer to the description in the above embodiment, and will not be repeated in the embodiments of this application.
