[0034] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0035] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application.

[0036] In order to more clearly demonstrate the data processing method for electronic tags provided in the embodiments of the present application, an application scenario that can be used to implement the method is first introduced.

[0037] Figure 1 Schematic diagram of the system architecture of the data processing method for electronic tags provided in one embodiment of the present application. Figure 1As shown, the cloud server includes multiple distributed microservices, each of which is deployed on a physical server, and the multiple distributed microservices together constitute an encrypted RFID security cloud service. The cloud server can be a public cloud, which provides a unified RFID security service. The terminal devices of various electronic tag manufacturers are registered in the public cloud to obtain their respective access user IDs. The cloud server generates an instruction set template for the electronic tag according to the universal tag attribute information of the electronic tag, such as the APDU (Application Protocol Data Unit) instruction template shown in the figure. The encryption machine in the cloud server performs encryption processing based on the project feature information of the project corresponding to the electronic tag to obtain the root key of the project, and stores it in the encryption card. The instruction set template, the encryption card and the project feature information are sent to the terminal devices of multiple electronic tag manufacturers, such as RFID manufacturer 1, RFID manufacturer, and RFID manufacturer as shown in the figure. The terminal device uses the parsing SDK (Software Development Kit) issued by the cloud server to parse the encryption card to obtain the root key of the project, parse the instruction set template, and obtain the universal instruction set in the instruction set of the electronic tag, wherein some instructions may vary depending on the electronic tag, and this part is handled as a placeholder by a universal wildcard. Based on the root key and the characteristic information of the electronic tag in the project characteristic information (the personalized RFID data shown in the figure), the personalized instruction set in the instruction set of the electronic tag is obtained, including the user account, subkey, personalized data, etc. of the electronic tag. The wildcards in the general instruction set are uniformly replaced by the personalized instruction set, that is, the instruction set to be burned into the chip is obtained, and the instruction set is burned into the chip of the electronic tag (the production line write data shown in the figure).

[0038] In another implementation, the cloud server and the terminal device of the electronic tag manufacturer are connected through the network, and the cloud server generates the general instruction set and personalized instruction set of the electronic tag, which are sent to the terminal device for burning. Specifically, the cloud server generates the instruction set template of the electronic tag according to the general tag attribute information of the electronic tag. The project identifier in the project feature information is encrypted by an encryption algorithm to obtain the root key of the project. The project identifier and the tag identifier are encrypted by the root key to obtain the subkey of the electronic tag. The instruction set template is parsed to obtain the general instruction set in the instruction set; some instructions will be different for different electronic tags, and this part is handled by general wildcards as placeholders. Based on the subkey and the feature information of the electronic tag in the project feature information, the personalized instruction set in the instruction set is obtained, and the wildcards in the general instruction set are uniformly replaced by the personalized instruction set, that is, the instruction set to be burned into the chip is finally obtained, and sent to the terminal devices of multiple electronic tag manufacturers for instruction set burning.

[0039] The present application embodiment provides a data processing method for an electronic tag. Figure 2 1 is a flow chart of a data processing method for an electronic tag according to an embodiment of the present application. The method can be applied to a data processing device for an electronic tag, which can be deployed in a server or other processing device. In some possible implementations, the method can also be implemented by a processor calling a computer-readable instruction stored in a memory. Figure 2 As shown, the method includes:

[0040] Step S201: Generate an instruction set template for the electronic tag according to the general tag attribute information of the electronic tag.

[0041] The method in this embodiment can be deployed in a cloud server, and the common tag attribute information of the electronic tag can be the common electronic tag attribute information of multiple projects, or the common attribute information of multiple electronic tags applicable to one project. The common electronic tag attribute information for multiple projects can include at least one of the following: chip brand, chip model, RFID protocol, etc. The common tag attribute information for one project can include at least one of the following: chip brand, chip model, RFID protocol, the tag personalized data requirements of the project, project-specific burning requirements, etc.

[0042] Step S202, encrypting the project feature information of the project corresponding to the electronic tag to obtain a root key of the project.

[0043] The project characteristic information may include project identification, project customization requirements, etc., and may also include personalized data corresponding to each electronic tag, such as product serial number, place of origin, material information, etc.

[0044] The cloud server can use a hardware encryption machine to encrypt the information representing the uniqueness of each project in the feature information of the project and generate the root key of the project.

[0045] Step S203: Process the instruction set template, the root key and the project characteristic information to generate an instruction set of the electronic tag. The instruction set is used for the electronic tag to realize the requirements corresponding to the project.

[0046] The server can generate the instruction set of the electronic label through the instruction set template, root key and project characteristic information, and send it to the terminal device of the electronic label manufacturer for instruction set burning. Alternatively, the instruction set template, root key and project characteristic information can be sent to the terminal device, and the terminal device can generate the instruction set of the electronic label.

[0047] Different projects have different requirements, so the instruction sets burned into the chip of the electronic tag are different. The instruction set is a collection of instructions for controlling the chip in the electronic tag. After the instruction set is burned into the chip of the electronic tag, the electronic tag production is completed. When using the electronic tag, the electronic tag is scanned by the device, the instructions in the instruction set are executed, the data stored in the electronic tag is decrypted, and information such as the chip brand and chip model are obtained, as well as information on the product corresponding to the project, such as origin and material information.

[0048] The data processing method for electronic tags provided in the embodiment of the present application is that the cloud server generates an instruction set template based on the general tag attribute information, which can meet the general requirements of multiple projects for the electronic tag instruction set. The project feature information is used as a consideration for generating the electronic tag instruction set, which can meet the differentiated requirements of the projects, thereby being compatible with multi-dimensional differentiated production line burning. The cloud server uniformly manages the instruction set burning of electronic tags of multiple projects, which can improve the efficiency of chip burning.

[0049] The specific implementation of the instruction set for generating electronic tags is shown in the following embodiment:

[0050] In one possible implementation, step S203 processes the instruction set template, the root key, and the project characteristic information to generate the instruction set of the electronic tag, including: step S2031, generating the subkey of the electronic tag based on the root key, the project characteristic information, and the tag identifier of the electronic tag; step S2032, generating the instruction set of the electronic tag according to the instruction set template, the subkey, and the project characteristic information.

[0051] In actual applications, the root key of the project is used to derive the unique identification of the electronic tag and the project characteristic information to obtain the subkey of the electronic tag. The subkey of the electronic tag corresponds to the electronic tag one by one. Among them, the cloud server can obtain the unique identification of the electronic tag from the user terminal. Password derivation refers to a string of ciphertext data obtained by encrypting a string of data factors with a root key as a new key. As long as the data factor does not repeat the last calculated new key value, it will not be repeated. The encryption algorithm can be AES (Advanced Encryption Standard) algorithm, 3DES (Triple Data Encryption Standard) algorithm, etc. The cloud server generates the instruction set of the electronic tag based on the instruction set template, the subkey of the electronic tag and the project characteristic information, and sends it to the user terminal for chip burning.

[0052] In this embodiment, the cloud server directly generates an instruction set for the electronic tag and sends it to the user terminal. The cloud server can achieve compatibility with multi-dimensional differentiated production line burning and improve the efficiency of chip burning.

[0053] The specific implementation of step S2032 is shown in the following embodiment:

[0054] In one possible implementation, an instruction set for an electronic tag is generated based on an instruction set template, a subkey, and project characteristic information, including: parsing the instruction set template to obtain a general instruction set in the instruction set; and obtaining a personalized instruction set in the instruction set based on the characteristic information of the electronic tag in the subkey and project characteristic information.

[0055] In actual applications, the cloud server parses the instruction set template to obtain the general instruction set in the instruction set. The general instruction set is a general instruction set for electronic tags of one or more projects. Some instructions may vary depending on the electronic tag, such as the user account, subkey, personalized data, etc. of the electronic tag. This part is handled by a general wildcard as a placeholder. The subkey and the feature information of the electronic tag in the project feature information (for example, the personalized data of the electronic tag) are used as variables to generate a personalized instruction set, and the wildcard in the general instruction set is replaced to obtain the instruction set to be burned into the chip of the electronic tag.

[0056] The specific implementation method of the cloud server generating the root key of the project is shown in the following embodiment:

[0057] In a possible implementation, step S202 encrypts the project characteristic information of the project corresponding to the electronic tag to obtain the root key of the project, including: encrypting the project identifier in the project characteristic information using an encryption algorithm to obtain the root key of the project.

[0058] In actual applications, the cloud server can use the unified root key and encryption algorithm of the cloud service to encrypt the project identifier, and use the project identifier as a derivation factor to obtain the root key of the project. The project identifier corresponds to the project one-to-one. The encryption algorithm can be the AES (Advanced Encryption Standard) algorithm, the 3DES (Triple Data Encryption Standard) algorithm, etc. The unified root key of the cloud service is pre-configured by the cloud server.

[0059] The specific implementation method of the cloud server generating the subkey of the electronic tag is shown in the following embodiment:

[0060] In a possible implementation, a subkey of the electronic tag is generated based on a root key, project feature information and a tag identifier of the electronic tag, including: using the root key to encrypt the project identifier and the tag identifier in the project feature information to obtain the subkey of the electronic tag.

[0061] Specifically, the combined string of the project identifier and the tag identifier is used as a derivation factor, and the root key of the project and the derivation factor are used to derive the key to obtain the subkey of the electronic tag, and the subkey and the electronic tag have a one-to-one correspondence. In this embodiment, the subkey of the electronic tag is dynamically derived from the project root key to ensure the high security of one chip and one key.

[0062] In one possible implementation, the instruction set template, the root key and the project characteristic information are processed to generate the instruction set of the electronic tag, including: sending the instruction set template, the root key and the project characteristic information to the terminal device of the electronic tag manufacturer, so that the terminal device parses the instruction set template to obtain the general instruction set in the instruction set of the electronic tag, and obtains the personalized instruction set in the instruction set of the electronic tag based on the characteristic information of the electronic tag in the root key and the project characteristic information.

[0063] In actual applications, in addition to generating the instruction set of the electronic tag through the cloud server, the instruction set template, root key and project feature information can also be sent to the terminal device of the electronic tag manufacturer. The terminal device uses the parsing SDK to parse the instruction set template to obtain the general instruction set in the instruction set of the electronic tag, and uses the root key to encrypt the project identifier and the tag identifier to obtain the subkey of the electronic tag. The subkey and the feature information of the electronic tag in the project feature information (for example, the personalized data of the electronic tag, etc.) are used as variables to generate a personalized instruction set, replace the wildcard in the general instruction set, and thus obtain the instruction set to be burned into the chip of the electronic tag.

[0064] In a possible implementation, the method further includes: performing an XOR operation on the root key of the project to obtain multiple key components of the root key, and sending them to a terminal device of the electronic label manufacturer so that the terminal device synthesizes the multiple key components to obtain the root key.

[0065] In actual applications, in addition to directly sending the project's root key to the terminal device, the cloud server can also process the root key, perform an XOR operation on the key and a random data to obtain multiple key components, and send them to the electronic tag manufacturer's terminal device. The terminal device synthesizes the multiple key components to obtain the root key, and then uses the root key and encryption algorithm to obtain the sub-key of each electronic tag.

[0066] Figure 3 is a schematic diagram of a key derivation process according to an embodiment of the present application. Figure 3 As shown, in this embodiment, two key derivation operations are performed. The cloud server uses the unified root key of the cloud service and takes the project identifier of each project as the derivation factor to derive the subkey of each project, such as project subkey k1, project subkey k2, and project subkey k3 as shown in the figure. Then, using the project subkey, the project identifier (project ID) and the tag identifier (tag ID) of the electronic tag are used as derivation factors to obtain the key of the electronic tag. Figure 3 As shown, using key k1, taking project ID and tag ID as derivation factors, since the tag IDs of tags A, B, and C are different, the keys Ak1, Bk1, and Ck1 corresponding to tags A, B, and C are obtained respectively; using key k2, taking project ID and tag ID as derivation factors, the keys Xk2, Yk2, and Zk2 corresponding to tags X, Y, and Z are obtained respectively; using key k3, taking project ID and tag ID as derivation factors, the keys Uk3, Vk3, and Wk3 corresponding to tags U, V, and W are obtained respectively.

[0067] In addition, the present application also provides a data processing method for an electronic tag. Figure 4 1 is a flow chart of a data processing method for an electronic tag according to an embodiment of the present application. The method can be applied to a data processing device for an electronic tag, which can be deployed in a terminal device or other processing device. In some possible implementations, the method can also be implemented by a processor calling a computer-readable instruction stored in a memory. Figure 4 As shown, the method includes:

[0068] Step S401, obtain the instruction set template of the electronic tag, the root key of the project corresponding to the electronic tag, and the project feature information of the project; the instruction set template is generated by the cloud server according to the general attribute information of the electronic tag.

[0069] The method in this embodiment can be deployed on the terminal device of the electronic label manufacturer. The terminal device receives the instruction set template of the electronic label, the root key of the project corresponding to the electronic label, and the project feature information of the project sent by the server. The instruction set template is generated by the cloud server based on the general attribute information of the electronic label. The specific generation method is shown in the above embodiment and will not be repeated here.

[0070] The project characteristic information may include project identification, project customization requirements, etc., and may also include personalized data corresponding to each electronic tag, such as product serial number, place of origin, material information, etc.

[0071] Step S402: Parse the instruction set template to obtain a common instruction set in the instruction set of the electronic tag.

[0072] The terminal device uses the parsing SDK (Software Development Kit) sent by the cloud server to parse the instruction set template to obtain the general instruction set in the instruction set of the electronic tag. The general instruction set is a general instruction set for electronic tags of one or more projects. Some instructions will vary depending on the electronic tag, for example, the user account, subkey, personalized data, etc. of the electronic tag. This part is handled by a general wildcard as a placeholder.

[0073] Step S403: obtaining a personalized instruction set in the instruction set of the electronic tag based on the root key and the project characteristic information.

[0074] Based on the root key and the characteristic information of the electronic tag in the project characteristic information, a personalized instruction set is obtained in the instruction set. The wildcards in the general instruction set are uniformly replaced using the personalized instruction set, that is, the instruction set that is ultimately to be burned into the chip is obtained and sent to the terminal devices of multiple electronic tag manufacturers for instruction set burning.

[0075] The data processing method for electronic tags provided in the embodiment of the present application is that the terminal device receives the instruction set template of the electronic tag, the root key of the project corresponding to the electronic tag, and the project characteristic information of the project sent by the cloud server, parses the instruction set template, and obtains a common instruction set in the instruction set of the electronic tag, which can meet the common requirements of multiple projects for the electronic tag instruction set. Based on the root key and the project characteristic information, a personalized instruction set in the instruction set of the electronic tag is obtained, which can meet the differentiated requirements of the project, thereby being compatible with multi-dimensional differentiated production line burning and improving the efficiency of chip burning.

[0076] In one possible implementation, a personalized instruction set in the instruction set of the electronic tag is obtained based on the root key and project characteristic information, including: generating a subkey of the electronic tag based on the root key, project characteristic information and the tag identifier of the electronic tag; and obtaining a personalized instruction set in the instruction set of the electronic tag based on the subkey and the characteristic information of the electronic tag in the project characteristic information.

[0077] In actual applications, the project identifier and the tag identifier are encrypted using the root key to obtain the subkey of the electronic tag. The subkey and the feature information of the electronic tag in the project feature information (for example, the personalized data of the electronic tag, etc.) are used as variables to generate a personalized instruction set. The subkey of the electronic tag corresponds to the electronic tag one by one. In this embodiment, the subkey of the electronic tag is dynamically derived through the project root key to ensure the high security of one chip and one key.

[0078] In a possible implementation, the root key of the project corresponding to the electronic tag is obtained in the following manner: receiving multiple key components of the root key sent by the cloud server, and synthesizing the multiple key components to obtain the root key.

[0079] In actual applications, in addition to directly sending the project's root key to the terminal device, the cloud server can also process the root key, perform an XOR operation on the key and a random data to obtain multiple key components, and send them to the electronic tag manufacturer's terminal device. The terminal device synthesizes the multiple key components to obtain the root key, and then uses the root key and encryption algorithm to obtain the sub-key of each electronic tag.
